【摘要】 为削弱自动谈判模型中谈判Agent对偏好信息汇报的主观度,引入直觉模糊区间数的多准则算法,得到各方案的区间直觉模糊集,并结合不完全确定的权系数信息建立非线性规划模型,得出谈判Agent对各属性的谈判权重。为克服遗传算法早熟现象,运用小生镜遗传算法对谈判空间进行全局快速寻优,提高收敛性。仿真计算表明该模型是有效的,而且精度高、数值稳定性好,能快速客观地辅助谈判Agent达成一致协议。更多还原

【Abstract】 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.更多还原
