Two multiple criteria Group Decision Support Systems based on mathematical programming and ranking methods

This paper presents two prototype Group Decision Support Systems based on multiobjective linear programming. The emphasis of the paper is on the operationalization of multicriteria modelling techniques through group decision support technology. The major components of the prototype systems include procedures for generating efficient solutions, preference aggregation, and ranking alternatives. Empirical results from a laboratory application and their implications in terms of user preferences and system performance are also provided.
