摘要
在深入分析相关信誉问题研究的基础上,结合网格环境以及在此方面同行所做前沿工作,通过引入Dempster-Shafer证据理论,提出一种新的支持网格的信誉评价模型,给出相应的信誉评价模型及算法.仿真结果表明,该模型较好地解决了网格实体信誉定量评价问题,具有良好的网格动态适应性及鉴别信誉欺骗行为的能力.
Based on deep analysis of relevant reputation research, a new Grid-Supported Reputation Evaluation Model is presented combined with advanced research work on Grid environment. In the presented model, Dempster-Shafer Evidence Theory is introduced and corresponding reputation evaluation algorithm is put forward. Simulation results show that the model can solve the quantitative evaluation problem of Grid entity reputation, and has nicer ability to adapt the dynamic of Grid and distinguish reputation deception.
