针对电子商务环境下集中采购中的双边多轮价格谈判过程,以讨价还价轨迹图为分析工具,在剖析现有基于传统趋势外推思想的成交价估计方法特点的基础上,提出了一类基于让价幅度加权思想的谈判成交价估计方法.新成交价估计方法符合谈判人的出价心理与习惯,较直接的反映了交易价格的形成规律.新方法的估计结果满足正常谈判条件,并且在第一轮报价后即可预估谈判成交价.新旧两类谈判成交价估计方法的实例对比分析表明,新成交价估计方法是可行和有效的.谈判成交价估计方法是集中采购价格谈判决策支持系统开发的重要基础. 相似文献

考虑公平关切的工期优化收益共享谈判 总被引:1,自引:0,他引:1
针对工程建设中工期优化问题,构建了立足于工程全生命周期角度的业主与承包商的收益共享谈判模型.设置了谈判双方均具有公平关切、仅业主具有公平关切、 仅承包商具有公平关切三种实验情景,研究了主体公平关切程度对谈判可行域、谈判成功结果、谈判效率等方面的影响.实验结果表明:谈判双方的公平关切程度越高, 谈判成功的可行域越小;主体适度提高公平关切程度,会导致工期优化幅度较大,但过度关注公平会导致双方成本大幅增长,不利于系统利润增长; 主体不同的公平关切程度会对自身收益产生不同影响;双方保持适度公平关切能够提高谈判成功率,缩短谈判周期. 相似文献

We usually decide to accept or reject the offer based on the utility function in the traditional automatic negotiation of E-commerce so that we reject the offers whose utility is lower than a specified value. Here we evaluate the acceptability based on the fuzzy set theory and the membership function. Since different issues have different effect on the negotiators, we state the combined concession in the multi-issue negotiation for the negotiators. We put forward a more practical negotiation model than the traditional negotiation model and give an example of its application in E-commerce. 相似文献

Negotiation is both an important topic in multi-agent systems research and an important aspect of daily life. Many real-world negotiations are complex and involve multiple interdependent issues, therefore, there has been increasing interest in such negotiations. Existing nonlinear automated negotiation protocols have difficulty in finding solutions when the number of issues and agents is large. In automated negotiations covering multiple independent issues, it is useful to separate out the issues and reach separate agreements on each in turn. In this paper, we propose an effective approach to automated negotiations based on recursive partitioning using an issue dendrogram. A mediator first finds partial agreements in each sub-space based on bids from the agents, then combines them to produce the final agreement. When it cannot find a solution, our proposed method recursively decomposes the negotiation sub-problems using an issue dendrogram. In addition, it can improve the quality of agreements by considering previously-found partial consensuses. We also demonstrate experimentally that our protocol generates higher-optimality outcomes with greater scalability than previous methods. 相似文献

Automated negotiation mechanisms can be helpful in contexts where users want to reach mutually satisfactory agreements about issues of shared interest, especially for complex problems with many interdependent issues. A variety of automated negotiation mechanisms have been proposed in the literature. The effectiveness of those mechanisms, however, may depend on the characteristics of the underlying negotiation problem (e.g. on the complexity of participant’s utility functions, as well as the degree of conflict between participants). While one mechanism may be a good choice for a negotiation problem, it may be a poor choice for another. In this paper, we pursue the problem of selecting the most effective negotiation mechanism given a particular problem by (1) defining a set of scenario metrics to capture the relevant features of negotiation problems, (2) evaluating the performance of a range of negotiation mechanisms on a diverse test suite of negotiation scenarios, (3) applying machine learning techniques to identify which mechanisms work best with which scenarios, and (4) demonstrating that using these classification rules for mechanism selection enables significantly better negotiation performance than any single mechanism alone. 相似文献
