Selected issues of design and implementation of Decision Support Systems

The paper presents selected issues related to design and implementation of model based Decision Support Systems (DSS). For over ten years the SDS Program has been involved in cooperation with various projects at IIASA and in collaborating research institutes. This cooperation has resulted in the development of many DSS, which in turn stimulated research on the theory and methodology of decision analysis. An overview of selected DDS developed within the cooperation with IIASA is presented. Different concepts of DSS are briefly discussed and one specific type of DSS, namely model based, aspiration--led DSS is characterized. Finally, selected problems of designing and implementation of a DSS are discussed in more detail. A short description of software packages developed within the cooperation with the MDA Project is provided. The paper also gives a short summary of recent activities of the Methodology of Decision Analysis Project and of the DSS software available from the MDA Project. v ..
