Opis:: The article presents the process of building a logistic regression model, which aims to support the decision-making process in medicine. Currently, there is no precise diagnosis for ulcerative colitis (UC) and Crohn's disease (CD). Specialist physicians must exclude many other diseases occurring in the colon. The first goal of this study is a retrospective analysis of medical data of patients hospitalized in the Department of Gastroenterology and Internal Diseases and finding the symptoms differentiating the two analyzed diseases. The second goal is to build a system that clearly points to UC or CD, which shortens the time of diagnosis and facilitates the treatment of patients. The work focuses on building a model that can be the basis for the construction of classifiers, which are one of the basic elements in the medical recommendation system. The developed logistic regression model will define the probability of the disease and will indicate the statistically significant changes that affect the onset of the disease. The value of probability will be one of the main reasons for the decision.

decision support system
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:: 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:: With continuous improvements in the function and performance of ship equipment, mechanisms of failure have become more and more complicated. To avoid over-maintenance or under-maintenance in existing routine ship maintenance strategies, a ship-level method for repair decisions based on the preventive maintenance concept is proposed in this paper. First, the anticipated repair demand levels of key components are calculated using an improved failure mode and effects analysis (FMEA) method; second, a Weibull distribution model is established, and the parameters are estimated using the maximum likelihood estimation (MLE) to predict the characteristic life of the equipment; then, logical decision principles and rule-based reasoning (RBR) are used to determine the ship repair level and repair timing. Finally, the feasibility and application value of the proposed repair strategy were verified by case studies, and a ship-level system for repair decisions was established.

evidential reasoning approach
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:: 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.

Opis:: 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.
Celem artykułu jest zaprezentowanie wyników symulacji przebiegu kolizji pomiędzy m/v „Baltic Ace” oraz m/v „Corvus J”. Analiza została przeprowadzona przy użyciu nawigacyjnego systemu wspomagania decyzji (NDSS) w sytuacji kolizyjnej. System ten wypracowuje propozycje manewru antykolizyjnego przy użyciu danych z AIS (system automatycznej identyfikacji) oraz ARPA (system automatycznego kreślenia nakresów radarowych). Następnie propozycje te są przekazywane użytkownikowi w formie graficznych rozet i danych alfanumerycznych. Informacje wykorzystane do analizy tej szczególnej sytuacji nautycznej zostały zaadaptowane z raportu Bahamas Maritime Authority jako ciąg sekwencji protokołu NMEA.

NAVDEC
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:: 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.
