Opis:

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:

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:

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.

Cloud computing presents scientists and engineers with new challenges related to the architecture of information systems and their use. This paper addresses the problem of deployment of decision supporting system in computing cloud. The author of the document presented the application of this approach that lies on intelligent discovery of web services within geographic information systems. Many important aspects of nowadays’ IT systems have been considered like the domain of Web GIS, network of agents architecture, semantics and ontology, integration of external knowledge bases, deployment of applications into the cloud. It has been proven that based on them, it is possible to create a software that uses a natural language to submit queries to a system whose operating environment is a PaaS (Platform as a Service) class platform. Another aspect discussed in this article was the approach to build so-called virtual organizations in which data and knowledge exchange takes place via web services. As an example, integration with Google Geocoding API is shown, where the web API provides geographic location based on the location expressed in natural language, e.g. home address, tourist point.

Ich nazwa pochodzi od zajmującego ważne miejsce w rachunku prawdopodobieństwa i statystyce twierdzenia Bayesa, które postuluje rewizję wcześniejszych przekonań w świetle nowych faktów. Wiedza dziedzinowa jest tu zakodowana w postaci grafu, którego topologia naśladuje przyczynową strukturę dziedziny.

Among many formal tools for supporting decision-making process Bayesian networks (belief) seem to be noteworthy. The name origins from Bayes' theorem, occupying an important place in probability and statistics, which postulates a revision of the earlier beliefs in the light of new facts. The knowledge is here encoded in the form of a graph, which mimics the topology of the causal structure of the domain.

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:

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.

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.

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 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.

Opis:

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:

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:

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:

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.

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.

Opis:

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.

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.

In medical decision making (e.g., classification) we expect that decision will be made effectively and reliably. Decision making systems with their ability to learn automatically seem to be very appropriate for performing such tasks. Decision trees provide high classification accuracy with simple representation of gathered knowledge. Those advantages cause that decision trees have been widely used in different areas of medical decision making. In this paper we present characteristic of univariate and multivariate decision tree. We apply those classifiers to the problem of acute abdominal pain diagnosis.

Opis:

A lot of companies have a problem with the selection of the type of computer network, because each of them has different characteristics and specifications. A businessman often does not know what he can expect from them and which type of network will allow him to fully exploit the potential of its business. The main objective of the work is to build a decision support system in this area. Intermediate target is to specify the characteristics or criteria which will be guided by a businessman in this selection. A comparative analysis of the type of access to the network using a case study was made in the work. The paper also developed the concept of a decision support system on the issue in question. As a result, six benchmarking criteria were specified and analyzed: security, data integrity, price, mobility, performance and configuration. As a result of the analysis, the final ranking was presented. Having used AHP method it showed which type of access to the network according to the given criteria provided by a businessman was the most suitable for him.

Opis:

Systemy wspomagania decyzji (SWD) w praktyce zarządzania nie są niczym nowym. Początek ich stosowania datuje się na połowę zeszłego wieku, ale w procesie ich rozwoju znacznie poszerzył się zestaw metod, które są wykorzystywane, aby ułatwić decydentom dokonywanie wyborów. Metodologia wspomagania decyzji opiera się przede wszystkim na logicznym wnioskowaniu oraz racjonalnych przesłankach ich podejmowania. Najnowsze badania interdyscyplinarne, prowadzone pod szyldem neuronauki poznawczej, pokazują jednakże, że bardzo istotne przy podejmowaniu decyzji są czynniki behawioralne i emocjonalne. Niestety, współczesne systemy wspomagania decyzji nie uwzględniają w wystarczającym stopniu tych aspektów. Zastosowanie technik neuronauki wydaje się jednak bardzo obiecującym kierunkiem rozwoju SWD. Celem artykułu jest analiza możliwości, jakie niesie ze sobą wykorzystanie narzędzi neuronaukowych w ramach systemów wspomagania decyzji, i wskazanie potencjalnych korzyści wypływających z uwzględnienia pozaracjonalnych determinant dokonywanych wyborów w procesie decyzyjnym.
Decision support systems (DSS) in management practice are nothing new. Their use dates back to the mid of the last century, but in the process of their development they have been greatly expanded with set of methods that are used to help policy makers to make choices. The methodology of decision support is based primarily on logical reasoning and reasonable grounds of their making. Recent interdisciplinary research, conducted under the name of cognitive neuroscience show, however, that very important factors in decision making process are also behavioural and emotional. Unfortunately, modern decision support systems do not sufficiently take into account these aspects. The use of neuroscience techniques seems to be a very promising direction in the development of the DSS. This article aims to analyse the possibilities offered by the use of neuroscience tools within the decision support systems and to identify potential benefits of taking into account non-rational determinants of the choices made in the decision making process.

Opis:

Integrated Coastal Zone Management is an emerging research area. The aim is to provide a global view of different and heterogeneous aspects interacting in a geographical area. Decision Support Systems, integrating Computational Intelligence methods, can be successfully used to estimate useful anthropic and environmental indexes. Bayesian Networks have been widely used in the environmental science domain. In this paper a Bayesian model for estimating the Sustainable Coastal Index is presented. The designed Bayesian Network consists of 17 nodes, hierarchically organized in 4 layers. The first layer is initialized with the season and the physiographic region information. In the second layer, the first-order indexes, depending on raw data, of physiographic regions are computed. The third layer estimates the second-order indexes of the analyzed physiographic regions. In the fourth layer, the global Sustainable Coastal Index is inferred. Processed data refers to 13 physiographic regions in the Province of Trapani, western Sicily, Italy. Gathered data describes the environmental information, the agricultural, fisheries, and economical behaviors of the local population and land. The Bayesian Network was trained and tested using a real dataset acquired between 2000 and 2006. The developed system presents interesting results.

Opis:

There many decision problems where numerous partial achievement functions are considered impartially which makes the distribution of achievements more important than the assignment of several achievements to the specific criteria. Such models are generally related to the evaluation and optimization of various systems which serve many users where quality of service for every individual user defines the criteria. This applies to various technical systems, like to telecommunication ones among others, as well as to social systems. An example arises in location theory, where the clients of a system are entitled to equal treatment according to some community regulations. This paper presents an implementation of decision support framework for such problems. This platform is designed for multiple criteria problems analyzed with the reference distribution approach. Reference distribution approach is an extension of the reference point method.

The paper introduces the process of safe ship control in collision situations using a differential game model with m participants. The basic model of process includes non-linear state equations and non-linear, time-varying constraints of the state variables as well as the quality game control index in the forms of game integral payment and final payment. As an approximated model of the manoeuvring process, a model of a multi-step matrix game in the form of a dual linear programming problem has been adopted here. The Game Control (gc) computer program has been designed in Matlab/Simulink software in order to determine the own ship safe trajectory. The considerations have been illustrated with computer simulation examples using the gc program for determining safe own ship trajectory in real navigation situations when passing commonly-encountered ships.

Opis:

This paper describes an application of the dynamic programming method to determine the safety of one’s own ship trajectory during encounter of other ships. A dynamic model of the process, with kinematic constraints of state and determined by a three-layer artificial neural network has been used for the development of control procedures. Non-linear activation functions in the first and second layers may be characterised by a tangent curve while the output layer is of a sigmoidal nature. The Neural Network Toolbox of the Matlab software has been used to model the network. The learning process used an algorithm of backward propagation of the error with an adaptively selected learning step. The considerations have been illustrated through an example implemented in a computer simulation using the algorithm for the determination of the safe ship trajectory in situations of encounter of multiple ships, recorded on the ship’s radar screen in real navigational situation in the Kattegat Strait.

Opis:

Potrzeby polskich producentów zbóż, rzepaku, buraka oraz innych upraw polowych w zakresie przekazywania za pośrednictwem Internetu informacji o konieczności podejmowania chemicznej ochrony upraw nie są zaspokajane w stopniu zadowalającym. Istnieje więc potrzeba intensykacji wysiłków umożliwiających zmniejszenie dystansu pomiędzy Polską i przodującymi w dziedzinie wykorzystania Internetu w ochronie roślin, krajami Ameryki Północnej i Europy Zachodniej. Realizację tak sformułowanego zadania należy rozpocząć od stworzenia warunków umożliwiających intensykację badań ukierunkowanych na opracowanie modeli matematycznych szacujących zagrożenie upraw ze strony agrofagów. Realizację tego celu powinno przyspieszyć utworzenie Wielkopolskiego Centrum Systemów Wspomagających Podejmowanie Decyzji w Ochronie Roślin, składającego się z dwóch współpracujących jednostek: Centrum Modelowania Rozwoju Patogenów oraz Centrum Oprogramowania, Walidacji i Upowszechniania Systemów Doradczych.
The needs of Polish farmers in the area of transmission via the Internet the information about optimal dates for pesticide use are not meet satisfactorily. There is therefore an urgent need to make efforts for reducing the distance between Poland and leading, in the field of Internet use in plant protection, countries of North America and Western Europe. Realization of that task should be begun by creating conditions for increasing research aimed at developing mathematical models for estimating the risk of crops from pests. The establishment of the Centre for decision support systems in Plant Protection consisting of two cooperating institutions: Center for the Development of Pathogen Development Modeling and Software Center, Validation and Dissemination of Advisory Systems should speed up realization of this objective.

Opis:

Decision Support Systems are powerful tools to help support making decisions. However, they are known to be customized for a specific purpose and can rarely be reused. Moreover, they do not support complex situations sufficiently. Our work addresses this challenge and consists in building a DSS that aims to help emergency managers to manage cases of crisis. The DSS is designed to be flexible and adaptive, so that it may be applied on different subjects of studies and whose behaviour may change with the change of its environment. We endowed it therefore with a multiagent layered core whose role is to represent dynamically and in real time the current situation, to characterize it and to compare it with past known scenarios. The final result of the DSS will help decision-makers to analyze the current crisis and its possible evolution. The RoboCupRescue simulation system is chosen as a test bed to illustrate and to test this approach.

Opis:

In this paper we present ae general concept of the consensus reaching process supporting by the group decision support systems. We proposed the idea which combines the mathematical direction based on “soft” consensus developed by Kacprzyk and Zadrożny [6] and relevant socio-psychological factor concerning fairness component. Essentially, we divide fairness approach in consensus reaching process on two possible directions: a fair distribution (fair resource allocation) and a fair final decision. We stress the benefits resulting from the implementation of proposed concept in the group decision support systems and point the direction of further model formalization.

Opis:

This paper presents the problem of the assessment of the supply chains in the context of their effectiveness. In this paper the concepts of a supply chain and effectiveness were characterized. The supply chain is a structure of entities which are connected with each other by the use of material and financial flows and functional, structural, technological, economic and information dependencies. Entities such as: suppliers, final recipients, entrepreneurs, warehouse facilities, supply centers, logistics operators, carriers, etc. perform material flows from suppliers to recipients. The concept of efficiency, in general terms, refers to economic rationality and means the relationship between the achieved or expected effects and the expenditures incurred. Additionally, indicators of measuring the effectiveness of the supply chain were described. In order to assess the effectiveness of the supply chain the decision model was developed. Optimization is crucial in decision support systems. The development of an appropriate model for mapping the behavior of a real object or system and formulating an optimization task is a necessary activity in effective management. This is even more important if we want to be competitive. Along with the development of decision support systems, as well as the development of systems for data acquisition on the system functioning, which feed optimization models in ever more detailed form, complex decision models are created that take into account many optimization criteria and require a large amount of data. It allows, however, to ensure the sustainable development of the system and simultaneous implementation of its basic tasks. The main aim of this paper is to present the stages and assumptions of the model for assessing the effectiveness of the supply chain. The main data input, constraints of the model, the criteria functions were determined.

Opis:

Artykuł przedstawia autorską koncepcję systemu automatycznej identyfikacji niebezpieczeństw (SAIN) w żegludze śródlądowej. System opiera się na dwóch równolegle działających metodach, a mianowicie na deterministycznym modelu matematycznym i systemie ekspertowym z logiką rozmytą. Tak zbudowany system wspomagania decyzji poza matematycznymi miarami uwzględnia również decyzje (zachowania) ekspertów, czyli nawigatorów żeglugi śródlądowej. Pozwala to na zwiększenie bezpieczeństwa pracy oraz wzrost efektywności i wydajności wykorzystania torów wodnych. W artykule przedstawiono problematykę integracji informacji pobranych ze specjalistycznych urządzeń tworzących system oraz metodykę działania samego systemu. Koncepcję autorskiego hybrydowego systemu wspomagania decyzji umieszczono w kontekście aktualnie rozwijanych systemów informacji rzecznej (RIS), co dodatkowo wskazuje na miejsce działania opracowanego systemu oraz jego praktyczne zastosowanie. W artykule omówiono podstawowe mechanizmy inteligentnych systemów transportowych, które przyczyniają się do wymiernych korzyści w zakresie ekonomiki transportu i bezpieczeństwa.
The paper presents a concept of the navigation system, automatic identification of hazards (SAIN) for inland waterways. The system is based on two parallel operating methods, namely the deterministic mathematical model and expert system with fuzzy logic. So the decision support system built outside the mathematical measures also take into account the decisions (behavior) expert (navigators inland waterway). This increases safety and increase the effectiveness and efficiency of use of the fairway. The article presents the integration of information taken from the specialized equipment to operate the system and methodology of operation of the system itself. The concept of hybrid decision support system placed in the currently developed river information services (RIS), which indicates the site of action drawn up the system and its practical application. The article discusses the key mechanisms of intelligent transportation systems that contribute to measurable benefits in the area of transport economics and security.

Opis:

Deliveries planning in transport systems is a complicated task and require taking into account a wide range of factors. Enterprises wanting to propose solutions that meet the clients’ needs and be competitive on the market must prepare their offer based on decision support systems including factors characteristic for the real process. The aim of the article is to present a concept of a decision support system based on a multi-criteria vehicle routing problem in real conditions (Real-World VRP). Taking into account the latest trends in the optimization of the delivery plan, the model includes three criteria - the cost, time and success rate of the delivery plan as a criterion relating to the quality of the delivery plan. Among other assumptions, it should be pointed out that the heterogeneous structure of the rolling stock has been taken into account, the number of which is not limited, the vehicles return to the place of origin. The travel time of the connection and the time of loading operations are random variables. The limited driver’s work time and driving time were also applied. The effect of the work presented in the article is the concept of the decision support system in the freight transport, taking into account the quality criterion of the delivery plan.

Opis:

We propose a decision support framework (DSF) assisting insulin therapy of diabetic children. Our DSF relies on a medical treatment graph (MTG), which models and graphically represents clinical pathways. Using the MTG, it is possible to plan and adapt medical decisions dependent upon the current health state of a patient and the progress of the treatment. Our MTG fits well with the requirements of clinical practice. The presented work is a cooperative effort of researchers in computer science and medicine. The MTG model has been thoroughly tested and validated using real-world clinical data. The usefulness of the approach has been confirmed by physicians.

The article presents the application of the decision tree classifier to the acute abdominal pain diagnosis. The recognition task model is based on a decision tree. In this model the decision tree structure is given by the experts. For the assumed structure of the decision tree the locally optimal strategy is considered. The problem discussed in the work shows a selection of different classifiers (parameters) to the internal nodes of the decision tree. Experiments conducted for selected medical diagnosis problem shows that the use of different parameters for k-NN classification can improve the quality of classification in comparison with the situation if it is used with the same parameter for all internal nodes of the decision tree.

The dynamic development of additive manufacturing technologies, especially over the last few years, has increased the range of possible industrial applications of 3D printed elements. This is a consequence of the distinct advantages of additive techniques, which include the possibility of improving the mechanical strength of products and shortening lead times. Offshore industry is one of these promising areas for the application of additive manufacturing. This paper presents a decision support method for the manufacturing of offshore equipment components, and compares a standard subtractive method with an additive manufacturing approach. An analytic hierarchy process was applied to select the most effective and efficient production method, considering CNC milling and direct metal laser sintering. A final set of decision criteria that take into account the specifics of the offshore industry sector are provided.

A significant part of the knowledge used in the production processes is represented with natural language. Yet, the use of that knowledge in computer-assisted decision-making requires the application of appropriate formal and development tools. An interesting possibility is created by the use of an ontology that is understandable both for humans and for the computer. This paper presents a proposal for structuring the information about the foundry processes, based on the definition of ontology adapted to the physical structure of the ongoing technological operations that make up the process of producing castings.
