R and D for group decision aid in Hungary by WINGDSS, a Microsoft Windows based Group Decision Support System

摘要

A flexible and complex Group Decision Support System for PC-s in Microsoft Windows environment is presented. Several real-life applications have been carried out with WINGDSS. The Multi-Attribute Decision Aid type system reflects the logical structure of the problem as well as the preferences and the expertise of decision makers. We assume a heterogeneous group in a soft negotiation situation. Both factual data and subjective factors will be taken into account when qualifying the alternatives. Arrival at a group ranking satisfactory to all members is supported by a series of possibilities to use WINGDSS interactively, and by integrating feedbacks from individuals. The interface to relational databases, the tree handling ‘AROMA’ modul for problem structuring, the dialog box editor, the built-in interpreter for evaluating the alternatives ensure the applicability of WINGDSS in various decision situations. Experiences with real life decision problems are reported.
