DEFINITION A spatial decision support system (SDSS) is an interactive, computer-based system designed to support a user or a group of users in achieving a higher effectiveness of decision making while solving a semi-structured spatial decision problem [10]. It lies at the intersection of two major trends in the spatial sciences: geographic information sciences (GIS) and spatial analysis [10]. W...

Applying evolutionary computation (EC) to multicriteria decision making addresses two diicult problems: (1) searching intractably large and complex spaces and (2) deciding among multiple objectives. Both of these problems are open areas of research, but relatively little work has been done on the COMBINED problem of searching large spaces to meet multiple objectives. While multicriteria decisio...

The paper presents a multicriteria decision support system, called MultiOptima. The system consists of three independent parts − MKA-2 system, MKO-2 system and LIOP-1 system and it is intended to support the decision maker in modelling and solving different problems of multicriteria analysis and linear and linear integer problems of single and multicriteria optimization. The class of the proble...

A new framework, Decerns, for multicriteria decision analysis (MCDA) of a wide range of practical problems on risk management is introduced. Decerns framework contains a library of modules that are the basis for two scalable systems: DecernsMCDA for analysis of multicriteria problems, and DecernsSDSS for multicriteria analysis of spatial options. DecernsMCDA includes well known MCDA methods and...

The paper deals with ideas of multicriteria decision support with the use of computer based systems. A negotiation problem is considered related to joint realization of a risky innovative project by two parties. It is considered as a multicriteria bargaining problem. A procedure enabling interactive multicriteria analysis and derivation of mediation proposals is proposed. Some results of experi...

A multicriteria decision support system called MultiChoice is presented in the paper. It is intended to support decision makers in solving various multicriteria analysis problems. Different well-known methods and software systems are considered. The structure, the functions and the user interface of the system are described.

The integration of GIS and multicriteria decision analysis has attracted significant interest over the last 15 years or so. This paper surveys the GISbased multicriteria decision analysis (GIS-MCDA) approaches using a literature review and classification of articles from 1990 to 2004. An electronic search indicated that over 300 articles appeared in refereed journals. The paper provides taxonom...

This paper presents a fuzzy multicriteria group decision making approach for selecting information systems projects. The inherent subjectiveness and imprecision of the selection process is modeled by using linguistic terms characterized by triangular fuzzy numbers. To avoid the complex and unreliable process of comparing fuzzy numbers usually required in fuzzy multicriteria analysis, a new algo...
