Decision making model of GJAHP based on genetic algorithms

The experts' opinions integration has always been an important part of group decision making. This paper analyses the consistency of general judgment matrix and proposes a model of group priority weight vector calculation. Through the analysis of this model, a genetic algorithms is designed, and values of some parameters are proposed. Since the Analytic Hierarchy Process in Generalized Judgemet(GJAHP) is an expansion of AHP, the proposed model has a wide applicability, which could be properly applied to the priority weight value aggregation of group AHP in its general sense.
