Opis:
Decision support systems (DSS) provide decision-makers with an interactive environment for analyses of information with various models to help solve unstructured and NP-hard problems. The important aspect of DSS is a technical and technological approach to the design and implementation of the above systems. A traditional approach to DSS engineering and implementation requires a great deal of effort for its maintenance. However, the enterprises would like to concentrate on its core competitiveness instead of non-core activities like IT maintenance. As a result of this, IT outsourcing has became a very popular event. Thus there is a growing need for intelligent decision support tools capable of assisting a decision maker in many problems in SMEs (Small and Medium Sized Enterprises). In this paper we present the use of declarative programming (constraint logic programming and relational SQL database) as an environment and framework for such decision support systems in an application service providing (ASP) model.

Opis:
The paper presents a concept of the new algorithm solving Last Moment Manoeuvre problem. Last Moment Manoeuvre means that action taken only by one vessel is not enough to avoid collision. This is why both vessels have to synchronize their manoeuvres to pass each other. The main focus of the proposed solution is concentrated on the procedure defining the best possible manoeuvre for each vessel when avoiding a collision is no longer possible. For simplification, the assumption that the parameters of the vessels involved in the Last Moment Manoeuvre meet Standards for Ships Manoeuvrability set out in the IMO resolution, will be adopted. The algorithm presented in the paper will be implemented and tested in the commercial system.
W artykule przedstawiono nowy algorytm rozwiązania, tzw. manewru ostatniej chwili. Pod tym pojęciem autorzy rozumieją manewr, gdy działania podjęte przez tylko jeden statek nie zapewnią uniknięcia kolizji. Dlatego oba statki muszą zsynchronizować swoje manewry, by minąć się bezpiecznie. Istota zaproponowanego rozwiązania sprowadza się do procedury definiującej optymalny manewr dla każdego statku, zapewniając jednocze-śnie zapobieżenie kolizji. Dla uproszczenia przyjęto założenie, że jednostki spełniają standardy dla sterowności statków ustanowione w rezolucji IMO. Zaproponowany algorytm będzie implementowany i przetestowany w systemie oferowanym komercyjnie.

Opis:
Scheduling problems appear frequently at different levels of decisions. They are usually characterized by many types of constraints, which make them unstructured and difficult to solve (NP-complete). Traditional mathematical programming approaches are deficient because their representation of constraints is artificial (using 0-1 variables). Unlike traditional approaches, constraint logic programming (CLP) provides for a natural representation of heterogeneous constraints. In CLP we state the problem requirements by constraints; we do not need to specify how to meet these requirements. In this paper we propose a declarative framework for decision support system (DSS) for constrained search problems implemented by CLP and relational SQL database. We illustrate this concept by the implementation of a DSS for scheduling problems with external resources in different production organization environments.

Opis:
We present how the conceptually and numerically simple concept of a fuzzy linguistic database summary can be a very powerful tool for gaining much insight into the essence of data that may be relevant for a business activity. The use of linguistic summaries provides tools for the verbalization of data analysis (mining) results which, in addition to the more commonly used visualization e.g. via a GUI, graphical user interface, can contribute to an increased human consistency and ease of use. The results (knowledge) derived are in a simple, easily comprehensible linguistic form which can be effectively and efficiently employed for supporting decision makers via the data driven decision support system paradigm. Two new relevant aspects of the analysis are also outlined which was first initiated by the authors. First, following Kacprzyk and Zadrożny [1] comments are given on an extremely relevant aspect of scalability of linguistic summarization of data, using their new concept of a conceptual scalability that is crucial for large applications. Second, following Kacprzyk and Zadrożny [2] it is further considered how linguistic data summarization is closely related to some types of solutions used in natural language generation (NLG), which can make it possible to use more and more effective and efficient tools and techniques developed in this another rapidly developing area. An application of a computer retailer is outlined.

Opis:
In this paper we present how scheduling problems can be solved in the concurrent constraint programming (CCP) language Oz. Oz is the first high- level constraint language, which offers programmable search, modularity, expressiveness and an interface to invent new constraints using C++. As an example of scheduling problem the job-shop scheduling problem with manpower resources representation was considered. The objective discussed here is the minimization of the makespan. Allocating manpower to the jobs is more complicated than allocating machines, as different jobs and operations require different manpower. This problem is strongly NP-hard. We proposed the constraint programming (CP) based approach to decision support in this environment. The most important features of CP are declarative problem modeling, allowing a clear separation between the problem statement (variables and constraints) and the resolution of the problem.

Opis:
The objective of the presented research is to construct a model of a patient's health that is based on the idea of cognitive map, a graphical knowledge-representation tool. The application of the proposed model for medical diagnosis is the practical goal of the research. Initially, we provide a brief review of the related works on medical decision support systems and cognitive maps. Afterwards, we sketch the general idea of the conceptual approach to the representation of medical knowledge and provide a new formulation of the medical diagnosis problem. Then, we define our model based on associational cognitive maps and show how it can be applied to diagnosis support. Due to the relative ease of understanding of cognitive map, the model can be easily interpreted and used, thereby making medical knowledge widely available through computer consultation systems. The application example presented is based on a relatively simple, real medical case.

Opis:
Constraint Programming (CP) is an emergent software technology for declarative description and effective solving of large combinatorial problems especially in the area of projects portfolio prototyping. The paper deals with multi-resource and multi-criteria problem in which more than one shared renewable resource type may be required by manufacturing operation and the availability of each type is time-windows limited. The problem belongs to a class of NP-complete ones. The aim of the paper is to present a knowledge based and CP-driven approach to resource allocation conflicts resolution framework. Proposed framework stands behind a methodology aimed at task oriented DSS tolls designing. The Portfolio Project Prototyping System designed due to this methodology provides a prompt and interactive service to a set of routine queries stated both in straight and reverse way. Multiple illustrative examples are discussed.

The report presents the simulation results of collision between m/v "Baltic Ace" and m/v "Corvus J". The analysis was performed by means of navigation decision support system (NDSS) in collision situations. This system (NAVDEC) works out anti-collision manoeuvre using AIS (Automatic Identification System) and ARPA (Automatic Radar Plotting Aids) data. Then they are processed by specialized computing algorithms and presented to the operator on a display in the alphanumeric and graphic forms. The data on the specific navigational situation from the report of Bahamas Maritime Authority was used for the generation of signals transmitted to NDSS as a sequence of NMEA strings.

Opis:
The known navigational systems in use and methods of navigational decision support perform information functions and as such are helpful in the process of safe conduct of a vessel. However, none of these known systems provides a navigator with ready solutions of collision situations taking account of all the vessels in the proximity of own ship, where the Collision Regulations apply. This paper presents verification results of NAVDEC - new Navigational Decision Supporting System created by research team from Szczecin Maritime University both for ocean going ships and pleasure crafts. Verification was carried out in real condition on board Motor Ferry ‘Wawel’ (m/f ‘Wawel’), which belongs to shipowner Polferries (PŻB). During the journey to/from Nynashamn system was tested from customer perspective. Few suggestions for improvements were issued, which were discussed in this article.
Znane nawigacyjne systemy i metody nawigacyjnego wspomagania decyzji pełnią funkcje informacyjne i bez wątpienia są pomocne w procesie bezpiecznego prowadzenia statku. Żadne z tych rozwiązań nie dostarcza jednak nawigatorowi gotowych rozwiązań sytuacji kolizyjnej z uwzględnieniem prawideł unikania kolizji jednocześnie wobec wielu jednostek będących w pobliżu. W artykule przedstawiono wyniki weryfikacji poprawności działania systemu NAVDEC - nowego systemu wspomagania decyzji nawigacyjnych opracowanego w Akademii Morskiej w Szczecinie z myślą zarówno o statkach pełnomorskich, jak i rekreacyjnych. Weryfikację wykonano w warunkach rzeczywistych na pokładzie promu m/f „Wawel” należącego do Polferries na trasie do Nynashamn i z powrotem pod kątem oczekiwań użytkownika. W wyniku testów zaproponowano pewne ulepszenia, które przedstawiono w artykule.

Opis:
Virtual Prototyping (VP) is a data-driven design process that promotes both knowledge reuse and innovation. High-profile applications in the automotive and aerospace industries have demonstrated its potential to significantly reduce prototype cycles, time to market, and total product cost. This paper addresses VP as a specialized application of Decision-Support Systems, and discusses common requirements for engineering design tools, as well as requirements specific to the design of electronic products, such as mobile phones. Motorola Labs' test bed for VP is introduced in terms of its open, agent-based architecture utilizing Java CORBA. One of the key principles of the VP System is the reuse of expert knowledge across multiple engineering domains. This is highlighted via several use cases, showing that the system can function not only as an Intranet-accessible repository of model services but also as an integral part of decision-making within the native CAD environment.

Opis:
Very often we complain about the decisions that were previously made. Yet the fact is that the decisions made were based on the knowledge we had before. By now we have gained more knowledge. Therefore the common problem of making decisions is that decisions are not made reliable enough because parameters in risk assessment and supply chain management are underestimated or not robust enough. In this paper we propose a framework that will try to predict future situations collectively and increase the reliability of decision making. Project management is the art of making right decision. Project managers are faced by huge array of choices. Decision analysis is used in strategic planning, operational management, and other areas of business. Decision analysis helps companies to determine optimal exploration and production strategies with uncertainties in cost, prices, and exploration prospects. This paper describes project management steps and the way they can be supported by Intelligent Decision Support system (IDSS). The main parameters assessed are total cost of the projects, time of the project total fulfilment, number of subcontractors, location factors, and etc. IDSS will enable to collect data, propose possible alternative decisions, and provide risk assessment.

Opis:
A project portfolio is referred to as an optimal combination of specified projects to best achieve defined goals of an enterprise. The goals may imply either economic and business strategies, or technical strategies. This paper presents an idea of project portfolio management in intelligent decision support systems (IDSS), which emphasizes on the problem of resource allocation, in particular cash. A rational way of distributing cash among different projects is modeled. We propose a concept of cash-flow dynamics module, which can be plugged into IDSS. The IDSS allows project managers to make decisions regarding the order of priority for projects' launching times based on risk and profitability of projects. This paper describes how this module can support cash-flow management processes, from budgeting for future periods to tracking real-time cash flow. Based on an analogy between cash-flow processes and physical flow of fluid, a cash-flow dynamics model is introduced. The theory of Bernoulli principle for cash-flow planning and tracking is applied.

Opis:
A calculation model of teaching costs in a university is a system of guidelines, notions and relations to facilitate an assessment of the costs generated by individual university departments, majors, subjects etc. The existing calculation models based on the assessment of costs with the use of precision data prove to be ineffective in practice. The major drawback of these systems is the fact that it is not possible to take into account non-precision data in relation to cost generating factors (e.g. the number of didactic groups, hourly rates etc.). This article presents the author’s own proposal of a cost calculation model based on the formalism of fuzzy logics (with the use of the L-R representation). On the basis of the model proposed, it is possible to assess the costs of an academic subject with imprecise information concerning cost generating factors, or the values of those factors are assessed which imply the values set of the cost of a subject.

Opis:
The development of e-commerce site operators in Indonesia is now faced with intense competition for defending the market segment, especially regarding how e-commerce sites are attracting consumers through specic marketing strategies. This study implements a decision support system approach to help marketers to determine price discount alternatives using the Elimination et Choix Traduisant la Realite (ELECTRE) method. The ELECTRE method is widely recognized for having good performance in analyzing customer behavior criteria; however, there is little information about discount analysis using the ELECTRE method. This study implements a method for consumer behavior simulation that can be aected by the criteria to make a purchase on a simulated e-commerce website. Our model estimates three parts of the matrices' analysis: (a) average value of discounted price (DP); (b) average value of pro- duct brand (PB); and (c) average value of purchase decision (PD). We used these as the main alternatives; e.g., price discounts as rst alternative (A1), brand discount as second alternative (A2), and purchase discount as third alternative (A3). Based on the results of the dominant aggregation matrix, the study found that the results are dominated by brand discount (A2). In other words, it is recommended for the decision maker to focus their discount on certain brands more precisely as a marketing strategy than price discount or purchase discount.

Przedstawiono najbardziej reprezentatywne przykłady wykorzystania narzędzi komputerowych do wspomagania procesów decyzyjnych: hurtownie danych, analizę finansową i modelowanie matematyczne. Wskazano też perspektywy wspomagania decyzji w zarządzaniu strategicznym na przykładzie negocjacji umów, dotyczących połączeń międzyoperatorskich.
The paper outlines three types of using decision support in telecommunications. The first type relates to application of data warehousing based decision support systems. In the second part, application of various analytical modeling and analysis techniques for decision support is discussed. Conventional network planning techniques are based on single criteria optimization algorithms. However, single criteria optimization has its limitations. An overview of multicriteria analysis in designing telecommunication networks is therefore discussed as well as an application of the ISAAP module for this purpose. The paper outlines also, in the third part, some possibilities of using multicriteria analysis for supporting strategic decision related to negotiating interconnection agreements in telecommunications.

Opis:
In this paper, an approach to evaluate R&D projects in telecommunications is presented. These Project have particular features that cannot be properly incorporated by classical evaluation methods. This approach incorporates different criteria, both quantitative and qualitative, and also management flexibility and uncertainty. Thus, it is an approach that can be applied to real data of R&D projects in a telecommunications company.

Opis:
Trust and reputation management is gaining nowadays more attention then ever as online commodity exchange and other open virtual societies became a widespread reality. Most widely used computational models use reputation metrics as global property assigned to each party. More sophisticated models try to use reputation as subjective property. While introducing subjective reputation there arise a need to model preferences of agents. In this paper we propose to use weighted ordered weighted average (WOWA) operator to support the decision maker in assessing available evidence about other's party behavior. The WOWA aggregation is defined by two weighting vectors: the preferential weights assigned to the ordered quantities and the importance weights assigned to several attributes. It allows one to express both the preference regarding sources of information by the corresponding importance weights and the compensation between attribute values aggregated by the preferential weights.

Opis:
During the previous two decades liner carriers within maritime shipping have broken the barriers from being pure transportation providers towards being logistics service providers. Most of the top 20 liner carriers worldwide hale set up spin-offs providing services from local booking up to 3rd party logistics services, combining the business advantages of tight linkages with liners together with the negotiation freedom with demanding customers by providing an extension of service coverage. Economical evaluations of transocean routes and global networks are of interest for decision makers responsible for business strategies as well as for operations. It is crucial to achieve appropriate judgements about which liner routes are profitable and how to build better service networks so that the companies' brand could be attractive to, e.g., ship- pers, including exporters, importers and forwarding agents. In this paper we discuss the corresponding trade-offs as well as related decision support systems of relevant service providers and companies.

Opis:
In the paper an approach to decision making in situations with non-pointlike characterisation and subjective evaluation of the actions is considered. The decision situation is represented mathematically as fuzzy multiobjective linear programming (fMOLP) model, where we apply the reduced fuzzy matrices instead of fuzzy classical numbers. The fMOLP model with reduced parameters is decomposable into the set of point-like models and the point-like models enable effective construction of an optimisation procedure - fBIP, see Wojewnik (2006ab), extending the bireference procedure by Michalowski and Szapiro (1992). The approach is applied to a fuzzy optimization problem in the area of telecommunication services.

Opis:
The current state of knowledge and the latest trends and examples of decision support systems (DSSs) are presented in this paper. Special emphasis was placed on a DSS proposal based on post-processed numerical weather forecasts operating in a real time. There is an essential need for decision support systems that can react to any incidents – including those that pose a risk to the natural environment or human activity in general. For this purpose an exemplary system has been prepared, which was – from its conception to implementation – the original idea of the author. The system enables communication with the user via a graphical user interface that controls the operation of the program, the course of the algorithm and the data flow. The system is modular, allowing the connection of other applications to carry out the work of a DSS. A basic view of the operating window and working panels have been designed for proper demonstration of various types of information and visualizations – the substantial products and results of the system. Further research in the field of DSS of this kind should be the implementation within the RIOT system of mechanisms of notification and response to crisis events related to extreme weather phenomena (whirlwinds, intensive rains, strong frosts or heats).

The risk analysis of ships’ accidents leads to the conclusion that one of the most important and dangerous stages existing during a ship’s trip is harbour entering and leaving. The use of the modern methods of risk estimation should improve both ship/harbour safety and the economic profitability of the taken decisions. This concerns especially the harbour entering by maximum acceptable size ships for the given harbour. The analysis of the indispensable data sets and the decision model algorithm proposed for the system of Szczecin– Świnoujście ports were described in the article. The use of the decision model, taking into consideration the dynamic current data and hydro-meteorological conditions, including their changes tendency and the possible changes of ship movement parameters, should increase the decision efficiency and hold the same safety level.

A multi-criteria model for determining the order size for materials used in production has been presented. It was assumed that the consumption rate of each material is a random variable with a known probability distribution. Using such a model, in which the purchase cost of materials ordered is limited, three criteria were considered: order size, probability of a lack of materials in the production process, and deviations in the order size from the consumption rate in past periods. Based on an example, it has been shown how to use the model to determine the order sizes for polyurethane adhesive and wood in a hard-coal mine.

Opis:
The Negotiation Support Systems often implement multiple criteria decision aiding (MCDA) techniques for building a negotiation scoring system. Those formal models should meet the needs, motivations, expectations, and cognitive abilities of users. In this paper, we try to explore the effects of decision maker’s subjective perception of ease of use, time requirements, interface, preference representation, and efficiency of a particular MCDA method on the choice regarding the future use of this method. The multinomial logistic regression model is built and analysed. The analysis is based on data from online decision making experiments, where three MCDA methods were implemented, i.e. AHP, SMART, and TOPSIS. The study provides several interesting findings, concerning the behavioural aspects of multiple criteria decision aiding in software support systems. Most of the users recommended TOPSIS as the best one for supporting decisions in the future. This is a fast technique, for which we used an attractive graphical interface, suggesting that these factors play a crucial role in the users’ choices. However, the causative regression model showed that the user’s positive experience in using a particular method, i.e. its effectiveness in solving an exemplary numerical case, has the highest impact on the method’s choice for future use. The second most important factor is the adequacy in representing the user’s preferences by this method. We show, however, that the strengths of effects and their significance may vary across the methods. Understanding the decision maker’s evaluations of the MCDA techniques may help build a cognitive negotiation support system that satisfies the user’s expectations.

Opis:
There are advantages in considering the routing problem in integrated communication networks as a multiobjective shortest path problem, having in mind to grasp eventual conflicts and trade-offs among distinct objectives and quality of services (QoS) constraints. On the other hand the utilisation of dynamic routing methods in various types of networks is well known to have significant impact on network performance and cost, namely in overload and failure conditions. This paper presents the detailed formulation of a proposal of a multiple objective dynamic routing method (MODR) of periodic state dependent routing type, enabling to represent distinct QoS related metrics and requirements in a consistent manner. The MODR method present formulation is based on a multiple objective shortest path model with constraints and is prepared to use implied costs as one of the metrics. Alternative paths tor each traffic flow are changed as a function of periodic updates of certain QoS related parameters estimated from real time measurements on the routes and trunks of the network. Such paths are computed by a specialised and efficient variant of a bi-objective shortest path constrained algorithm, developed for the MODR, enabling to incorporate flexible requirements on the QoS metrics. The architecture of the routing system is discussed together with the features of its main modules. An illustrative example of application of the MODR path calculation module to a circuit-switched type network using blocking probability and implied cost as metrics, is also presented, considering different overload conditions.

Therefore, the thorough analyses are carried out to determine the best solution under specific circumstances before any decisions are made. This paper presents techno-economic model, which was implemented and used to carry out analyses for one of the biggest city in Poland. To take uncertainty into consideration the stochastic approach was applied providing more robust solution, therefore, improving the safety of investment. Analyses concern FTTH (fibre to the home) technology, type of generic FTTx network architecture. It uses optical fibre in local telecommunication loop, what is becoming more and more popular. Presented results show the usefulness of techno-economic surveys in planning access networks development. The appropriate choice of network parameters, such as the aggregation ratio, is essential and could significantly influence the investment profitability.

Opis:
Multi-criteria decision-making (MCDM) methods are associated with the ranking of alternatives based on expert judgments made using a number of criteria. In the MCDM field, the distance-based approach is one popular method for receiving a final ranking. One of the newest MCDM method, which uses the distance-based approach, is the Characteristic Objects Method (COMET). In this method, the preferences of each alternative are obtained on the basis of the distance from the nearest characteristic objects and their values. For this purpose, the domain and fuzzy numbers set for all the considered criteria are determined. The characteristic objects are obtained as the combination of the crisp values of all the fuzzy numbers. The preference values of all the characteristic object are determined based on the tournament method and the principle of indifference. Finally, the fuzzy model is constructed and is used to calculate preference values of the alternatives. In this way, a multi-criteria model is created and it is free of rank reversal phenomenon. In this approach, the matrix of expert judgment is necessary to create. For this purpose, an expert has to compare all the characteristic objects with each other. The number of necessary comparisons depends squarely to the number of objects. This study proposes the improvement of the COMET method by using the transitivity of pairwise comparisons. Three numerical examples are used to illustrate the efficiency of the proposed improvement with respect to results from the original approach. The proposed improvement reduces significantly the number of necessary comparisons to create the matrix of expert judgment.

Opis:
Evidence-based medicine can be effective only if constantly tested against errors in medical practice. Clinical record database summarization supported by a machine allows allow to detect anomalies and therefore help detect the errors in early phases of care. Summarization system is a part of Clinical Decision Support Systems however it cannot be used directly by the stakeholder as long as s/he is not able to query the clinical record database. Natural Query Languages allow opening access to data for clinical practitioners, that usually do not have knowledge about articial query languages. Results: We have developed general purpose reporting system called Ask Data Anything (ADA) that we applied to a particular CDSS implementation. As a result, we obtained summarization system that opens the access for these of clinical researchers that were excluded from the meaningful summary of clinical records stored in a given clinical database. The most significant part of the component - NQL parser - is a hybrid of Controlled Natural Language (CNL) and pattern matching with a prior error repair phase. Equipped with reasoning capabilities due to the intensive use of semantic technologies, our hybrid approach allows one to use very simple, keyword-based (even erroneous) queries as well as complex CNL ones with the support of a predictive editor. By using ADA sophisticated summarizations of clinical data are produced as a result of NQL query execution. In this paper, we will present the main ideas underlying ADA component in the context of CDSS.

Opis:
The problem of selecting 3PL (Third Party Logistics) suppliers is a major issue in the management of the supply chain and the improvement of the production management of a manufacturing company. A 3PL supplier can be defined as a company that provides contract logistics services to a manufacturer, supplier or main user of a product or service. It is called a third party because the logistics provider does not own the products but participates in the supply chain between the manufacturer and the user of a given product. In actual cases, several decision-makers intervene in the selection of 3PL suppliers and each one has his own points of view and wishes to take into account criteria which are not generally the same for all the decision-makers. Furthermore, the criteria have different weights. In this study, we propose a method to solve this problem. It consists of a combination of the fuzzy Stepwise Weight Assessment Ratio Analysis (SWARA) method with the Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS). The objective is to optimize the decision-making process and have another, more dynamic model and satisfy the needs of the decision-maker. Fuzzy SWARA is one of the new methods being used for ranking evaluation criteria based on decision makers’ expected degree of importance to determine the weights of evaluation criteria (Selçuk, 2019). This method can be used to facilitate estimation of decision makers’ preferences regarding the meaning of attributes in the weight determination process. TOPSIS is a multi-criteria method for identifying solutions from a finite set of alternatives (Behzadian et al., 2012). To the best of our knowledge, this combination has not been developed in the literature, especially in the third-party logistic problems. The proposed model will be implemented to solve a 3PL problem of a company selling steel products.

The paper describes results of introductory research focused on possibility to use location data available in a mobile network for the analysis of transport system status and efficiency. The details of a system capable of detecting abnormal traffic situation (accidents, heavy congestion) are described. This system (called VASTAR) uses a neural network to learn and store certain characteristic of the analyzed part of a road system. Based on a measured divergence from normal characteristic, a notification about non-typical situation is triggered. The results of a computational experiment using real-world location data and simulation of abnormal situation are provided. The proposed system can be a relatively low cost way to improve competitiveness of a mobile network operator by allowing him to offer new type of informational service. It could also aid municipal authorities by providing support for decisions regarding road traffic control and management and be used by emergency services as a monitoring an alarming tool for detecting abnormal road traffic situations when other means of observation are unavailable.

The support system enables us to improve the selection process of the ERP solution, as well as to evaluate the productivity of the implementation and calculate Total Cost of Ownership. The concept of the support system is based on both a proposed model of the project, driven enterprise and a determined structure of business processes. The model of the enterprise is closely related to the structure of the ERP system. In this paper the most important performance indices of the system are proposed which decide about the implementation success of ERP. Especially, the evaluations of ERP implementation are taken into consideration based on the proposed indices that enable us to determine the productivity of ERP in a company. The illustrative examples are given.

The aim of the paper is to outline a project focussing on the development of a new type of ship weather routing solution with improved uncertainty handling, through better estimation of ship performance and responses to sea conditions. Ensemble forecasting is considered to take into account the uncertainty levels that are typical of operations in a stochastic environment. Increased accuracy of weather prediction is achieved through the assimilation of real-time data, measured by an on-board monitoring system. The proposed system will allow smooth integration of short-term Decision Support Systems for ship handling in dangerous or peculiar situations with long-term Decision Support Systems for weather routing. An appropriate user interface is also a critical part of the project and it will be implemented in a commercial Electronic Nautical Chart environment. A prototype of the full system will be installed and tested on a commercial vessel in regular operations and under real environmental conditions.

Opis:
Systemy GIS oferują bogate narzędzia analityczne do przetwarzania danych, które również w Polsce stopniowo zaczynają być wykorzystywane do wspomagania decyzji. Pojawia się w związku z tym pytanie: jakie jest ryzyko związane z decyzją podjętą na podstawie analiz GIS? Na ryzyko podjęcia nieprawidłowej decyzji ma wpływ na pewno jakość danych źródłowych znajdujących się w bazie. Zwykle jednak nie tylko dane są podstawą podjęcia decyzji, ale wyniki ich przetworzeń. Dane źródłowe podlegają przekształceniom, są wykorzystywane jako dane wejściowe w różnych modelach. Wynik analizy jest obciążony zarówno niedokładnością danych źródłowych, jak również niedokładnością wykorzystywanych algorytmów i nieadekwatnością modeli do rzeczywistości. W systemach GIS, tworzonych w Polsce, rzadko gromadzi się informacje o dokładności danych źródłowych. Z kolei wykorzystywane oprogramowanie GIS tylko sporadycznie umożliwia analizę wpływu dokładności danych na wynik przeprowadzonej analizy. Problem ten jest pozostawiony do rozwiązania indywidualnemu użytkownikowi. W niektórych narzędziach GIS ma on do wyboru najbardziej, popularną obecnie, metodę Monte Carlo. Metoda ta, pomimo, że jest uniwersalna, tzn. może być wykorzystywana właściwie we wszystkich analizach GIS, ma dwie wady: analizy trzeba wykonywać setki razy, żeby oszacować dokładność wyniku analizy, a poza tym nie pozwala ona na określanie przestrzennego rozkładu dokładności analizy. Alternatywą są metody analityczne lub empiryczne, o ile znane są wykorzystywane w systemie GIS algorytmy obliczeniowe. Przedstawiona powyżej problematyka, dotycząca wpływu dokładności danych na ryzyko podejmowania decyzji z wykorzystaniem systemów GIS, została omówiona szerzej w niniejszej publikacji. Porównano w niej wyniki analizy przestrzennych wykonanej z uwzględnieniem wpływu dokładności danych źródłowych oraz bez uwzględnienia tego faktu. Problem przenoszenia się dokładności danych źródłowych na wynik analizy przestrzennej pokazano na przykładzie wyboru nowej lokalizacji pod zabudowę. W analizie uwzględniono dokładność numerycznego modelu terenu (DTM). Umożliwiło to oszacowanie ryzyka związanego z podjęciem decyzji wyboru lokalizacji i koniecznością wykonania nieplanowanych prac ziemnych w celu wyrównaniem terenu.
There are many GIS tools for data analysis, also applied in Poland to decision support. The following question can appear: what is the risk of a decision based on the GIS analysis? GIS data quality certainly affects on the decision risk. Usually not only raw data are analyzed, but also the results of data transformations. Data are often transformed in GIS systems and used in different models as input data. Results of transformation are influenced by the original data quality (especially accuracy) and model/algorithm reliability. In GIS databases in Poland, information on data quality is very rare gathered. On the other hand, GIS software only occasionally delivers tools for algorithm and function accuracy analysis. The problem is left individually to the user. In some software, the popular Monte Carlo method is implemented. The method is very universal, it means that can be applied in almost all GIS analyses Monte Carlo has also disadvantages: analyses must be carried out hundreds times, and the spatial distribution of the results error is difficult to obtain. Analytical or empirical methods are an alternative if the algorithms implemented in GIS software are known. In the paper, the risk connected to the GIS analyses based on the data with known accuracy is presented. Spatial analysis is performed by hard methods, without data quality consideration and assuming some data uncertainty. Error propagation is presented in the paper based on a new urban area example and the DTM accuracy was considered in the spatial analysis. The risk of ground leveling caused by DTM inaccuracy was evaluated.

This study provides a systematic review of the existing academic literature describing the key components of eMaintenance. The current literature is reviewed by utilizing a number of academic databases including Scopus, SpringerLink and ScienceDirect, and Google Search is used to find relevant academic and peer-reviewed journal articles concerning eMaintenance. The literature describes eMaintenance as an advanced maintenance strategy that takes advantage of the Internet, information and communication technologies, wireless technologies and cloud computing. eMaintenance systems are used to provide real time analyses based on real time data to offer a number of solutions and to define maintenance tasks. The collection and analysis of appropriate maintenance and process data are critical to create robust ‘maintenance intelligence’ and finally improvements in manufacturing costs, safety, environmental impact, and equipment reliability. This paper describes how the scientific discussion on eMaintenance has expanded significantly during the last decade, creating a need for an up-to-date review. As a conclusion, three research gaps in the area of eMaintenance are identified, including evaluating the benefits of eMaintenance, agreeing on a comprehensive definition, and developing tools and structures for cooperative eMaintenance.

Opis:
This article presents an integrated approach to optimize the different functions in a supply chain on strategic tactical and operational levels. The integrated supply chain model has been formulated as a cost minimization problem in the form of MILP (Mixed Integer Linear Programming). The costs of production, transport, distribution and environmental protection were adopted as optimization criteria. Timing, volume, capacity and mode of transport were also taken into account. The model was implemented in the LINGO package. The implementation model and the numerical tests are presented and discussed. The numerical experiments were carried out using sample data to show the possibilities of practical decision support and optimization of the supply chain.

Opis:
Our research objective is to design a system to support legal decision making using the multi-agent blackboard architecture. Agents represent experts that may apply various knowledge-processing algorithms and knowledge sources. Experts cooperate with each other using the blackboard to store facts about a current case. Knowledge is represented as a set of rules. The inference process is based on bottom-up control (forward chaining). The goal of our system is to find rationales for arguments that support different decisions for a given case by using precedents and statutory knowledge. Our system also uses top- -down knowledge from statutes and precedents to interactively query the user for additional facts when such facts could affect the judgment. The rationales for various judgments are presented to the user, who may choose the most appropriate one. We present two example scenarios in Polish traffic law to illustrate the features of our system. Based on these results, we argue that the blackboard architecture provides an effective approach to modeling situations where a multitude of possibly conflicting factors must be taken into account in the decision making.

Opis:
Constraint programming (CP) is an emergent software technology for declarative description and effective solving of large combinatorial problems especially in areas of integrated production planning. In that context, the CP can be considered as a well-suited framework for development of decision making software supporting small and medium size enterprises in the course of Production Process Planning (PPP). The problem considered regards of finding of computationally effective approach aimed at scheduling of a new project subject to constraints imposed by a multi–project environment. In other words, we are looking for an answer whether a given production order specified by its cost and completion time can be accepted in a given manufacturing system specified by available production capability, i.e., the time-constrained resources availability. The problem belongs to a class of multi-mode case project scheduling problems, where the problem of finding a feasible solution is NPcomplete. The aim of the paper is to present the CP modeling framework as well as to illustrate its application to decision making in the case of a new production order evaluation. So, the contribution emphasizes benefits derived from CPbased DSS and focuses on constraint satisfaction driven decision-making rather than on an optimal solution searching.

Opis:
Decision making supported by task-oriented software tools plays a pivotal role in a modern enterprises. That is because commercially available ERP systems are not able to respond in an interactive on-line/real-time mode. It means a new generation of DSS that enable a fast prototyping of production flows in multiproject environment as well as an integrated approach to a layout planning, production routing, batch-sizing and scheduling problems is needed. In that context, the constraint logic programming techniques allowing declarative representation of a decision making problem provide a quite attractive alternative. So, some issues regarding modelling of decision making and searching strategies development are discussed in the contribution. The results obtained are implemented in a software package supporting production flow planning in the SMEs. Illustrative example of the ILOG-based software application is provided.

Opis:
Nowadays, the requirements and expectations of universities are increasing along with globalization. The functions of Research and Development and the doctorate programmes which aim to support education and train the academic staff, came to the fore with globalization. The doctorate programmes in European countries cannot be updated fast enough and quotas for these programs are insufficient in some regions – faster balancing seems to be the must. The Decision Support System (DSS) can be a solution to the problem. In this study, the candidates’ demand of the universities, the public-private organizations and R&D centres are included to a model. As a result DSS will help us identify the need for candidates and develop PhD planning strategies by analysing the current situation of the university policies through the innovative model balancing the supply-demand for PhD candidates – including formulae of doctorate implementation (recently introduced in Poland).

Opis:
A quantitative risk analysis (QRA) should provide a comprehensive, informative and balanced picture of risk, in order to support decisions. To achieve this, a proper treatment of uncertainty is a prerequisite. Most approaches to treatment of uncertainty in QRA seem to be based on the thinking that uncertainty relates to the calculated probabilities and expected values. This causes difficulties when it comes to communicating what the analysis results mean, and could easily lead to weakened conclusions if large uncertainties are involved. An alternative approach is to hold uncertainty as a main component of risk, and regard probabilities as epistemic-based expressions of uncertainty. In the paper the latter view is taken, and we describe what should be the main pillars of a risk description following this approach. We also indicate how this approach should relate to decision-making. An important issue addressed is how to communicate the shortcomings and limitations of probabilities and expected values. Sensitivity analysis plays a key role in this regard. An example is included to illustrate ideas and findings.

Opis:
Supply Chain Management (SCM) is a very important part of the industrial world, especially in the manufacturing sector. The development of the business world affects the complexity of the supply chain due to the lack of logistics infrastructure, quality of materials and components, and much more. Supply chain disruption risk mapping needs to be done due to high uncertainty, which is overcome by implementing a decision support system. Based on the background of the problem, supply chain disruption mapping uses the help of the Six Sigma method, which consists of 5 stages: Define, Measure, Analyze, Improve, and Control (DMAIC). The measurement of disturbance also uses the Failure Mode and Effect Analysis (FMEA) approach to prioritize risk. Risks that have a high assessment and cause failure need to be prioritized for improvement. This study aims to map supply chain disruptions in the current manufacturing industry based on the barriers, resistances, and causes detected for making a decision support system prototype. By implementing a decision support system in the supply chain process, it is hoped that the manufacturing industry can minimize potential losses from existing risks.

The paper discusses the impact of the decision-making profiles on the consistency of rankings obtained by three multiple criteria methods, i.e. DR, AHP and TOPSIS. The online decision making experiment was organized, based on an electronic questionnaire which is a hybrid of the internet survey system and the decision support system. The participants of the experiment were 418 students of Polish universities. To describe the decision-making profile, the REI test was used which allows to distinguish two decision-making styles: rational and intuitive. The Kendall rank correlation coefficient was used to test the consistency of the rankings obtained by the considered methods. Using different grouping methods, the relationship between the decision profile and the ability to express one’s preferences by means of these methods, that differ in cognitive requirements, was examined. The results of the research may be helpful for supporting the decision-maker in decision processes by choosing the method that fits their profile best.

Opis:
Intelligent decision system (IDS) is a window-based software package that has been developed on the basis of the evidential reasoning (ER) approach, a recent development in handling hybrid multiple criteria decision analysis (MCDA) problems with uncertainties. In this paper, the evidential reasoning approach will be briefly described first, and its major differences from and the relationships with conventional MCDA methods will also be discussed. Then the main features, advantages and benefits of IDS will be demonstrated and explained using two application examples: supplier pre-qualification assessment and customer satisfaction survey analysis, which have been investigated as part of the research projects led by the authors and funded by the UK government and the EC. It is concluded in the paper that the ER approach can be used not only to deal with problems that traditional methods can solve, but also to model and analyse more complicated decision problems that traditional methods are incapable of handling.

Opis:
Increased competition has led businesses to compete with each other in streamlining supply chain processes, especially in the manufacturing sector. Supply Chain Management (SCM) determines the success of industrial business processes because it regulates product flow regarding integration, performance, and information. However, several problems have emerged in the supply chain process, such as a lack of coordination in the production queue, difficulties in forecasting trending products, and suboptimal production capacity. To address these issues, the role of information technology is crucial for implementing a Decision Support System (DSS). This study aims to develop a DSS to improve the supply chain processes. The research method used is Extreme Programming (XP) with a qualitative approach through a questionnaire. The research process involves collecting data, defining boundaries and problems, and designing, coding, and testing the system. As a final step, evaluation is carried out by distributing surveys to obtain valid satisfaction results. This research produces a DSS that has applicability in marketing, accounting, and production processes. The application of DSS in the furniture manufacturing industry can help manage the movement of resources, optimize strategic networks, and assist decision-making in the supply chain process.

The telecommunications operators have to manage one of the most complex systems developed by human beings. Moreover, the new technological developments, the convergence of voice and data networks and the broad range of services still increase this complexity. Such complex object as telecommunication network requires advanced software tools for their planning and management. Telecommunications operators collect large volumes of the data in various databases. They realize that the knowledge in these huge databases might significantly improve various organizational strategic and operational decisions. However, this knowledge is not given explicitly, it is hidden in data. Advanced methods and algorithms are being developed for knowledge extracting. In this paper we will focus on using data mining for solving selected problems in telecommunication industry. We will provide a systematic overview of various telecommunications applications.

Opis:
Enterprise Resource Planning (ERP) are nowadays a software packages that can support all business activities of enterprises [1], [8], [10], [11]. The production enterprises often implement an ERP systems to improve important functions in such functional areas as sales, product design and technology, material management, purchasing or production planning. Absolute majority of them implement ERP in administration areas such as human resource, controlling, financial accounting or capital assets. The implementation of ERP is expensive and time-consuming process that often can fall flat. The enterprises that successfully implemented ERP don’t want to change the system long time to unique disturbances. But employers of the enterprise realize only the transactions in ERP that are necessary for property workflows and managers analysis. The lack of important data in the ERP system can result with impossibility of strategic analyses performance [12], [14], [16]. In the situation ERP can not support strategic decisions of managers too. In the paper an ERP evaluation method based on data analysis is proposed. The authors of the article claim that value of ERP system is consist of two important components: possibility for improving of critical business processes and possibility for critical decision support. The model of ERP evaluation system for project driven enterprise is proposed. The illustrative examples are given.

Opis:
The article presents a proposition of a universal model of knowledge conflict resolving using consensus methods, which can be used in a multi-agent decision support system. Knowledge conflicts often appear, when individual agents generate different solutions of the same problem. It is very difficult for the user – decision-maker to make a good decision because the analysis of solutions generated by agents is very time-consuming and the decision must be made quickly. Moreover, selecting one of the decisions on the basis of the experience of the decision-maker is very risky, because he/she could choose the worst solution. Consensus methods, however, allow to agree, on the basis of the solutions generated by agents, one solution, which is a compromise. As a consequence, reducing the time and decreasing the risk level of the decision taking process, to enable the functioning of the enterprise in more flexible.

Opracowany model jest prototypem projektowanego systemu wspomagania decyzji nawigacyjnych na statku morskim.
The complexity of the navigation process and necessity of ensuring a possibly high level of safety, with continually growing vessel traffic intensity, ships' tonnage and speeds developed at sea, call for research on navigational decision support systems. This article presents the assumptions and a model of such system design. The Unified Modeling Language (UML) has been used for system modelling. The UML allows presenting the designed system from various perspectives in a manner easily perceived by its future users as well as its creators: analysts, designers and programmers. The developed model provides a basis for building a prototype of the designed system of navigational decision support on the sea going vessel.

In this work we obtained the solution of increasing of adequacy of models of multicriteria evaluation for the project and management decision support systems. Modifications of the utility functions of partial criteria and the procedure for calculating their values are proposed, which makes it possible to improve the accuracy of approximation of the preferences of the person making the decision, as well as significantly reduce the time for calculating their values. For the parametric synthesis of universal multicriteria estimation models based on the Kolmogorov-Gabor polynomial, an improvement in the method of comparator identification by calculating the Chebyshev point and the discrepancy vector is proposed.

Opis:
This article presents a model of a navigational decision support system on a sea-going vessel. Apart from basic information functions, the system executes tasks typical of decision support systems. Its basic functions and performance are described. Problems of navigational data acquisition and integration as well as navigational situation analysis and assessment are discussed. The system generates solutions of collision situations. Navigators' knowledge is implemented in the system by using artificial intelligence tools and methods. Its key feature is the capability of explaining generated conclusions. The prototype system, built using the presented model, is being tested in real conditions onboard ship.
W artykule przedstawiono model nawigacyjnego systemu wspomagania decyzji na statku morskim. System realizuje obok podstawowych funkcji informacyjnych zadania typowe dla systemów wspomagania decyzji. Przedstawiono główne funkcje systemu oraz ich realizację. Scharakteryzowano zagadnienia akwizycji i integracji danych nawigacyjnych, funkcje analizy i oceny sytuacji nawigacyjnej. System umożliwia generowanie proponowanych rozwiązań sytuacji kolizyjnych. W systemie zaimplementowano wiedzę nawigatorów przy zastosowaniu m.in. metod i narzędzi sztucznej inteligencji. Istotną cechą systemu jest możliwość objaśniania generowanych wniosków. Na podstawie przeprowadzonej analizy modelowanego systemu, opracowano diagramy pakietów, stanowiące agregację elementów modelu. Przedstawiony model struktury systemu stanowił podstawę do opracowania architektury fizycznej. Uwzględniono środowisko funkcjonowania systemu. Stanowią je statkowe urządzenia i systemy nawigacyjne, będące źródłem informacji dla systemu. W systemie wyróżniono trzy moduły - aplikacje działające jednocześnie, realizujące funkcje systemu. Pierwsza z nich odbiera komunikaty z sensorów, a po ich selekcji i integracji przesyła zagregowane dane do drugiej aplikacji - programu zarządzającego. Rezultaty procesów przetwarzania wysyłane są do trzeciej z aplikacji -GUI, której zadaniem jest zobrazowanie sytuacji nawigacyjnej na ekranie monitora oraz komunikacja nawigatora z systemem. Prototyp wykonany na podstawie prezentowanych modeli jest testowany w warunkach rzeczywistych na statku morskim.

Opis:
Zastosowanie narzędzi GIS we wspomaganiu działalności i organizacji przedsiębiorstwa wymaga kilku różnych podejść w celu zapewnienia kompleksowego wspomagania. Referat przedstawia kilka możliwych koncepcji zastosowania GIS do rozwiązania niniejszego zagadnienia. W kolejności przedstawia się na wybranych przykładach: wspomagania działalności przedsiębiorstwa (koncepcja odwzorowania dużego zakładu przemysłowego; oraz w szczególności lokalizacja w nim linii produkcyjnej), planowanie zagadnień związanych z zadaniami przeciw pożarowymi (na przykładzie hali produkcyjna małego przedsiębiorstwa o podwyższonym zagrożeniu pożarowym), i w końcu serwis urządzeń linii produkcyjnej (dużego zakładu produkcyjnego). Przedstawione w referacie przykłady wspomagania mają wspólną cechę: a mianowicie opisują problemy wymagające uwzględnienia aspektów geograficznych/przestrzennych do ich rozwiązania.
Application of GIS in supporting the activities and organization requires several different approaches to ensure a comprehensive support. The paper presents some possible idea of using GIS to solve this problem. In order presented to selected examples: support the activities of the company (the concept of mapping a large industrial plant, and in particular the location of the production line), planning issues related to the tasks against fire (for example the hall production of small industrial plant with increased fire risk), and finally service of the production line (large plant). The examples in the paper support have in common: describe the problems – to solve them – that need to take into account aspects of geographical/spatial.

Opis:
All definitions for integrated control agree that maximum emphasis should be put on prevention by using resistant cultivars and cultural measures. Moreover, the use of plant protection products should be limited to the essential minimum using Decision Support Systems (DSSs) that integrate and organise all relevant information. Computer-based DSSs that require weather information and regular late blight scouting inputs have been developed and validated in a number of European countries. In the frame of the EU concerted action “European network for development of an integrated control strategy of potato late blight (EU.NET.ICP)” several DSSs were validated in 1999-2001. The overall conclusion was that in most cases the use of DSSs combined a good disease control with a reduction of fungicide input. The DSSs can be used as a PC-version but more and more, parts of information are delivered to users by phone, fax, e-mail, SMS and websites on the Internet. An important task for the near future is to update the DSSs with information on the epidemiology of the new aggressive population of Phytophthora infestans. Issues such as (1) the influence of temperature and relative humidity on the infection process, (2) the role of primary inoculum sources (seed, oospores, volunteers, dumps), (3) the role of secondary inoculum sources (distance, severity), (4) control of early blight and (5) resistance ratings for foliar and tuber blight have to be addressed in order to be able to formulate a robust control strategy that effectively controls late (and early) blight with a minimum input of fungicides.

Opis:
Wychodząc na przeciw zapotrzebowaniu na informacje w nowoczesnej produkcji roślinnej IUNG-PIB podjął w 2005 roku temat badawczy mający na celu budowę "Systemu wspomagania decyzji w zakresie produkcji roślinnej" (SWDPR), którego użytkownikami będą producenci, służby rolne i urzędy. System koncentruje się na prognozowaniu terminów zabiegów agrotechnicznych i zaleceniach odnośnie prac polowych w wybranych uprawach w oparciu o bieżące i historyczne dane meteorologiczne. Koncepcja systemu SWDPR zakłada integrację "Internetowego systemu wspomagającego podejmowanie decyzji w integrowanej ochronie roślin" z modelami zrealizowanymi w projekcie na podstawie istniejących algorytmów, opracowanych wcześniej w Zakładzie Agrometeorologii i Zastosowań Informatyki IUNG-PIB oraz nowo opracowanych modeli wykorzystujących dane meteorologiczne do sygnalizowania faz fenologicznych roślin uprawnych oraz precyzowania dawek nawożenia azotowego.
In order to fulfil the demand for information in modern plant production, IUNG-PIB undertook a research project in 2005 with the aim of building the Decision Support System in Plant Production (PPDSS). The target users of the system will be farmers, advisors and the administration. The system concentrates on forecasting of the agricultural measures and recommendations on the field works in selected crops using the current and historic weather data. The concept of the PPDSS is to integrate the "Internet Decision Support System in Integrated Pest Management" with the models constructed within the project on the basis of the existing algorithms that had been worked out at the Department of Agrometeorology and Applied Informatics previously. Newly-elaborated models using weather data to signal plant development stages and specify precise nitrogen-fertiliser doses will be also incorporated into the system.

Opis:
The paper concerns joint allocation and transportation as an optimization problem in selected supply networks. The network consists of a set of suppliers of the raw material, a set of production units and a set of product receivers. The raw material is treated as fast perishing good like vegetables or fruits. The production units are described by time models. In the optimization process, the time of the production and cost of the transportation is taken into account. The objective function is in general non-convex function of raw material allocation and transportation plans of the raw material and the product. To solve the problem considered, exact and heuristic algorithms have been developed and presented. To solve convex problems, solver Lingo developed by Lindo systems is proposed. The idea of a computer decision supported system integrating all presented algorithms is presented as well as four numerical examples illustrating some properties of the assumed supply network model.

The aim of this study was to test the effectiveness of an econometric model with dichotomous (binary) explanatory variables in the approximation and prediction of different kinds of cyclicality (annual, monthly, weekly, and daily) of demand for telephone services. The analyses were conducted with the use of data provided by the selected telecommunication network operator. The data included hourly combined demand for specified telephone services (in seconds) of outgoing calls within the framework of the particular subscriber group (business or individual), the given day, the particular month, and the specific category of connection. All kinds of the cyclicality were confirmed in models with 70 explanatory variables (i.e. in models without holidays). The inclusion of the variables set denoting specific holidays improved goodness of the models fit to the data. The econometric modelling of cyclical components and the forecasting of it with the use of dichotomous variables was effective.

Opis:
In the last decades, clinical evidence and expert consensus have been encoded into advanced Decision Support Systems (DSSs) in order to promote a better integration into the clinical workflow and facilitate the automatic provision of patient specific advice at the time and place where decisions are made. However, clinical knowledge, typically expressed as unstructured and free text guidelines, requires to be encoded into a computer interpretable form suitable for being interpreted and processed by DSSs. For this reason, this paper proposes an ontological framework, which enables the encoding of clinical guidelines from text to a formal representation, in order to allow querying, advanced reasoning and management in a well defined and rigorous way. In particular, it jointly manages declarative and procedural aspects of a standards based verifiable guideline model, named GLM-CDS (GuideLine Model for Clinical Decision Support), and expresses reasoning tasks that exploit such a represented knowledge in order to formalize integrity constraints, business rules and complex inference rules.

The learning vector quantization (LVQ) network was used to classify the ECG ST segment into different morphological categories. Due to the lack of data in the ST elevation categories, the classifier was only trained to identify different types of ST depressions (horizontal, upsloping and downsloping). The accuracies were 91%, 85% and 65% respectively for the training, validation and testing data respectively. Despite the low accuracy for the testing data, most of the mis-classifications were downsloping ST depression being classified as horizontal ST depression. We concluded that more data and more training are needed in order to train the LVQ to recognize other morphological types of ST deviation and to improve the accuracy.

Opis:
Wprowadzenie od 1 stycznia 2014 roku zasad integrowanej ochrony roślin ma na celu zapewnienie bezpieczeństwa wytwarzanej w procesie produkcji rolniczej żywności. Jednym z elementów zagwarantowania konsumentom zdrowej żywności jest racjonalne stosowanie środków ochrony roślin. Do możliwości prawidłowej ochrony roślin należy stosowanie środków ochrony roślin w optymalnym terminie, kiedy przekroczony został wyznaczony próg ekonomicznej szkodliwości. Do tego celu służą m.in. wcześniej ustalone wartości progów szkodliwości oraz systemy wspomagania decyzji. W łanowych doświadczeniach z pszenicą ozimą porównano zastosowanie ochrony fungicydowej na podstawie tradycyjnego schematu (faz rozwojowych), w których rolnicy wykonują zabiegi opryskiwania, z ochroną według wskazań systemu wspomagania decyzji. Zastosowanie ochrony z uwzględnieniem wskazań systemu wspomagania decyzji pozwoliło na zmniejszenie występowania chorób liści i kłosów oraz wpłynęło na zwiększenie plonu i masy tysiąca ziaren.
Introduction of integrated plant protection on 1 January 2014 has been aimed at ensuring safety of food coming from the agricultural production process. One of the elements of providing consumers with healthy food is reasonable use of plant protection products. Right plant protection includes use of plant protection products at the optimal time, when the established threshold of economic harmfulness is reached. This purpose is served by, among other things, earlier establishment of the values of thresholds of harmfulness and decision support systems. Stand experiments on winter wheat compared use of fungicide protection according to the traditional scheme (of developmental stages), where farmers conduct spraying procedures with protection according to recommendations of decision support system. Adopting protection according to recommendations of the system enabled to reduce the prevalence of leaf and ear diseases and resulted in higher yield and thousand grain weight.

The article includes presentation of fuzzy numbers application in projects prioritizing at manufacturing and service providing enterprises. The following criteria have been applied as a basis for projects prioritizing analysis in enterprise: NPV index, linked with the enterprise strategic aims, project execution cost, project time, project scope and risk. As the criteria selected were of measurable and non-measurable character in projects prioritizing evaluation, the fuzzy decision making system has been developed, in which a linguistic value has been defined for each criterion of projects prioritizing. Knowledge base has been developed afterwards, presenting cause-effect dependencies in projects prioritizing. Knowledge base consisted of conditional rules. Fuzzy system of decision making in project prioritizing has been developed in MATLAB application. The decision making fuzzy system established, constitutes an efficient tool for projects prioritizing, on the basis of criteria given and concluding system developed. The obtained analysis results provide basis for the decision making parties to set the projects execution sequences.

The article presents a proposal of use a decision table to support the decision-making process in scope of maintenance management in mining companies. In particular, it refers to decisions related to evaluation and improvement of mining machinery use in the mining production process. The article presents the theoretical foundations of decision tables building and characteristics of the most important stages of creating this table. This whole process was tried to refer specifically the mining industry. For this reason, during construction of the decision tables, the results of research on the effectiveness of the selected mining machines were used. The conducted research provided a lot of data, information and knowledge on the work of the particular mining machines, especially regarding the number and reasons for unplanned breaks during the machines’ work. The developed decision table will consist of conditions, rules and actions whose purpose is to define the recommendations for the particular groups of participants in the mining production process. The obtained results will form the basis for the development of the recommendations and proposals of actions to improve the level of use of mining machines. The authors focused mainly on the practical use of tables to support the decision-making process regarding maintenance and improvement of effectiveness of mining machines. The obtained results confirm the validity of the adopted assumptions. Decision tables can become an important tool that supports the decision-making process within mining companies.

Opis:
Dynamiczny rozwój technologii informatycznych i teleinformatycznych znajduje coraz większe odzwierciedlenie w obszarze informatycznych systemów wspomagających ratownictwo i zarządzanie kryzysowe. Charakterystyczne dla każdej ze służb warunki działań wpływają na różnorodność zaimplementowanych rozwiązań informatycznych. W przypadku Państwowej Straży Pożarnej - co zaprezentowane będzie w artykule - istnieje stosunkowo duża jednorodność. W opracowaniu autor przedstawia wyniki badań nad Systemem Wspomagania Decyzji "SWDST", przeprowadzone w ubiegłym roku na poziomie powiatu (miasta). Opracowanie zawiera krótką charakterystykę systemu, zakres implementacji i wspomagania systemu jak i poszczególnych jego części.
The time of dynamic information and multi - information system development have been gaining popularity on the crisis management and rescue operation decision support systems field. Environmental differences between emergency services are the main causes that the decision support systems are different each other. The article shows that the State Fire Service dispatcher centers have nearly the same solution. The paper presents results of the research on Decission Support System called "SWDST" that were being carried out on the county (municipal) level last year. The article briefly describes system characteristic, the range of system and modules implementation and supporting.

Opis:
In this article suggest some new approaches to solving the problems of medical data analysis and their personalization. To accomplish this was proposed to create a decision support system to the execution of sequence stages of analysis of patient's data. The main stages of development and design of decision support systems that enable to make decomposition of control process and describe the relationship between input and output control flows. Applying the theory of decision trees during construction of decision trees of decision support system is due to the formation of a sequence of questions asked by the doctor when searching an individual approach when choosing a treatment. Decision tree creates a hierarchical structure of rules. This approach allows you to present the logic of sequence issues by doctor in solving the medical problem history and it makes possible to simulate decision making process by physician when selecting treatment scheme. Search the target value of output of decision medical support system makes it possible to select top of graph system that is located with more probability on the best way to the target. Important step in addressing the process of personalizing treatment schemes is estimated function that is based on Bayes theorem. Weight of occurrence next event corresponds to the highest value of the posterior probability of occurrence of the next state, given the time-dependent input parameters. Proposed improved method of decision-making for personalization standard schemes by modifying the method of decision-making based on decision trees considering relationship between the input parameters and evaluation function and result of its works is a personalized therapeutic scheme of treatment. It analyzed the quantitative results of applying the proposed method and existing for determining personalized schemes.

Opis:
The objective of this paper is to present the results of research carried out to develop a design method for Smart Cities systems. The method is based on the analysis of design cases of Smart Cities systems in cities, the selection of the city appropriate to the requirements for implementation and application. The Case Based Reasoning method was used to develop the proposed design methodology, along with mechanisms of the conversion of project processes and roles to Rational Unified Processes (RUP). The prerequisite for the proposed method is that the enterprise manager must be knowledgeable about high-level Smart Cities system architecture and the design framework applied. The authors, being themselves knowledgeable about architecture of this kind and about project environments which implement KPI models, propose a generic solution applicable to any environments and system architectures.
Celem artykułu jest prezentacja wyników badań nad opracowaniem metody projektowania systemów Smart Cities. Metoda ta bazuje na analizie przypadków projektowania systemów Smart Cities w miastach, wyborze spełniającego wymagania zdecydowanego na wdrożenie ośrodka i zastosowaniu. Do budowy proponowanej metody projektowania wykorzystano Case Based Reasoning oraz mechanizmy konwersji procesów i ról projektowych do procesów zunifikowanych RUP. Warunkiem stosowania proponowanej metody jest wiedza kierującego przedsięwzięciem o wysokopoziomowej architekturze systemu Smart Cities oraz stosowanych ramach projektowych. Autorzy posiadając wiedzę o takiej architekturze, a także o środowiskach projektowych implementujących modele KPI, proponują rozwiązanie generyczne, które mogą być wykorzystywane dla dowolnych środowisk i architektur systemów.
