一种基于灰色系统理论的分布式信任模型
A distributed trust model based on grey system theory
摘要
Abstract
The trust model can be introduced into open Multi-Agent System (MAS) to help an agent to choose interaction partners. A distributed trust model GTrust is proposed to resolve the inaccurate information problem, in which the grey system theory is adopted. In GTrust, in order to guide the agent to utilize the recommendation from witnesses reasonably and avoid the negative impact from all kinds of inaccurate factors, a mechanism is designed to rate the witnesses' recommendation action,and the grey fixed weight clustering approach is used to determine the trust to witnesses. GTrust makes decision only based on the actual interaction results and ignores the source of inaccuracy, which is a practical choice in the complex environment. Simulation results show that GTrust can achieve better utility than other trust models either in a static environment, or a dynamic environment.关键词
