在制造网格资源市场中,一些资源服务提供者(RSPs)利用其拥有的信息优势制造混同均衡,使得资源服务需求者(RSDs)在信息不完美情况下无法辨别资源质量的高低.为此,文中提出了基于精炼贝叶斯均衡的制造网格资源交易,在制造网格系统架构的支持下,RSPs通过承诺赔偿价格作为信息传递手段,使RSPs达到分离均衡的目,的,从而防止低质量产品的RSPs模仿高质量产品而向RSDs发送错误信号.仿真结果显示,此博弈模型有一个稳定、合理、RSPs不会主动偏离的精炼贝叶斯分离均衡.
In the manufacturing grid (MGrid) resource market, some resource service providers (RSPs) with resource information superiority tend to make a pooling equilibrium. Therefore, resource service demanders (RSDs) cannot evaluate resource quality owing to the imperfect information. In order to solve this problem, this paper proposes a resource trading approach of manufacturing grid based on the perfect Bayesian equilibrium. In this approach, with the support of MGrid system architecture, RSPs promise a compensation for the display of resource quality, thus achieving in separating equilibrium and preventing low-quality RSPs from sending out a higher compensation that high-quality RSPs would promise. Simulated results show that the proposed game model achieves a stable, reasonable and perfect Bayesian separating equilibrium, from which RSPs would not deviate initiatively.
