    摘要:

    针对电子交易应用领域,提出一种私有信息和有时间约束的、基于卖方多提议和买方评价的多属性自动协商模型.买方协商策略简化为对卖方每一回合提交的一个或多个提议进行评价,卖方则根据时间和资源依赖策略确定提议的整体让步效用,根据买方评价和协商历史确定不同的让步属性组合和让步幅度,从而生成若干等效的新提议.该模型能有效减轻系统的通信和计算负担,提高解的收敛速度,在一定程度上改善协商效率和质量,并且在买方效用函数为线性时保证较优的联合效用.

    Abstract:

    To support the electronic transaction,a multi issue autonomous negotiation model based on sellers’ multi proposals and buyers’ evaluation is presented with the premise of private information and limited time.The strategy of the buyer agent is simplified to evaluate the one or several proposals generated by the seller agent in every round of negotiation.The seller agent,according to time or/and resource dependent strategy,calculates the whole utility concession;and different combinations of conceded issues and the utility reduction of each are decided on the basis of the buyer’s evaluation and the negotiation history.Then,several new proposals of the same utility are put forward by the seller.This model helps to relieve the system of communication and computation burden,speed up the convergence of result and improve the efficiency and quality of the negotiation with a good joint utility when the buyer utility function is linear.
