Interactive support for fuzzy trade-off evaluation in group decision making

In this paper, the authors are concerned with constructing interactive support systems for group decision making using fuzzy utility evaluation. In particular, fuzzy indifference experiments for articulating diversified value trade-offs in collective choice are discussed in the multiobjective environments. The fuzzy indifference curve is derived along with the fuzzy scaling constants for single-attribute utility functions. The intelligent decision support systems are used for supporting this process. With this device, some notions for heuristic construction of the fuzzy multiattribute utility function are suggested.
