Automatic Negotiation Model Based on Niche Genetic Algorithm
Li Yi-ling · Jisuanji gongcheng · 2011
A multi-criteria ranking method about interval-valued intuitionistic fuzzy sets is introduced into the automatic negotiation model to weaken the subjectivity degree of preference information report from negotiation Agent and the interval intuitionist fuzzy sets of alternatives are obtained.Considering the incomplete certain information on weights,a nonlinear programming model is developed and the weight of various attribute is obtained.In order to overcome the precocious phenomenon on Genetic Algorithm(GA),the Niche Genetic Algorithm(NGA) is proposed to search optimization and improve astringency.Simulation test shows the model is feasible and effective,the precision is high and the value-stability is good,which can help negotiation Agent to reach fast a mutually beneficial agreement objectively.
