Opis:
We propose a methodology to support decisions on how to construct rankings of objects which account for decision makers' preferences. As it is not always so that objects to be ranked are known upfront, the methodology is focused on constructing ranking algorithms rather than rankings themselves. The methodology builds on Multiple Criteria Decision Making paradigms. To operationalize it we provide a consistent interactive framework which allows the decision maker to express his preferences with respect to objects directly, with respect to the criteria selection process (multiple criteria model building), and with respect to attributes resulting from the selected criteria. The methodology is illustrated by a numerical example of municipality rankings.

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.

Opis:
The paper presents the declarative approach to design of a reference model aimed at project prototyping. The reference model contains the finite set of decision variables, their domains and linking those constraints, i.e. can be seen as a kind of Constraint Satisfaction Problem. Consequently, the model considered can be treated as a knowledge base specifying both a class of enterprises and the projects that could be conducted on their base. So, the model provides a platform for rapid prototyping of alternative versions of project scheduling. The routine queries can be formulated in the straight or reverse way. In that context, the proposed reference model can be implemented in constraint programming (CP) techniques

Opis:
Even the best technology will be ineffective if not used appropriately, therefore education and training about cybersecurity principles and programs are essential components of any cybersecurity strategy. This article presents selected models of the decision support theory from the point of view of cybersecurity education. The analysis of scientific literature and the available research results serve as a base to characterize approaches to raise the awareness of decision-makers about potential cyber threats and the development of appropriate attitudes and the conscious use of information systems and digital resources. The main part of the article is devoted to the issue of the use of teaching methods to increase the involvement of learners. It also describes examples of selected models of the game theory used in IT security education, including examples of simulation games dedicated to decision-making in the domain of IT security.

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:
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:
SAR (Search and Rescue) operation is a complex process, often carried out in the absence of resources and time. Every single minute matters, as it puts the lost person in more danger. Therefore, it is really crucial to plan and coordinate SAR operation effectively. Because the search area is often very extensive, any leads about where to look first are invaluable. This can be achieved by modelling lost person’s behaviour based on the data from past operations. Generated results present probabilities of finding a subject in different segments of the search area, which might benefit the planning and the execution phases of the operation. The authors evaluate one of the commonly used modelling methods and propose several ways to improve it, together with some preliminary evaluation results and an already implemented system, which incorporates the described methodology.

The article proposes a model of the system supporting the decision-making process relating to the radio operator on board a ship after a distress alert is received by a Digital Selective Calling (DSC) controller working on VHF channel 70. The model is aimed at the implementation into the system of radiocommunication event management. The system takes into account the existing Radio Regulations. The model makes use of Petri nets, which are elements of graph theory. The time domain is comprised in the developed graph, and the states (places) and transitions capable of autonomous functioning are separated, as are those places and transitions requiring direct operator action based on empirical knowledge.

Opis:
Web caching is the subject of intense research and development since it seems to be very promising area. Web caching means storing copies of frequently used objects (documents) geographically close to users requesting them to reduce network load, servers load and user response times. Cache can be situated in different locations between user and servers with original content. It seems that the most significant improvement can be achieved by using the proxy server - a dedicated web server. Various parameters affect web cache performance: cache size, limitations on document sizes or documents removal policy. Several metrics are used to evaluate this performance: hit rate for example is the ratio of documents obtained by using the cache mechanism comparing to the total number of documents requested. Choosing adequate parameters for interesting traffic patterns to improve cache performance is not a trivial cache management problem. Prototype tool based on multicriteria model analysis and supporting such web cache management is presented. Simple case was examined where small number of sets of cache parameters (variants), miniature traffic representation and only two performance measures are considered.

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:
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.
