网格环境下的信誉评价及管理模型研究

Study on Reputation Evaluation and Reputation Management Model Under the Grid Environment

将在分布式环境下适应的信誉评价算法进行改进使其适用于网格环境中,以网格环境下的安全合作为目标,结合网格环境以及在此方面同行所做的前沿工作,提出一种新的基于Dempster-Shafer证据理论的支持网格的信誉评价算法,以适应网格实体信誉定量评价的要求,解决网格信誉描述的不可测量性和模糊性问题,并给出相应的信誉管理模型。

The research background of this thesis is modified reputation evaluation algorithms in distributed environment in order to utilize them into Grid environment, Presenting a new Dempster- Sharer - Theory - Based Grid - Supported Reputation Management Model combined with the Grid environment and advanced research work in point, in order to adapt to the requirements of Grid entities reputation quantitative evaluation, the immeasurability and fuzzy problems of Grid credibility description are resolved, further put forward the relevant reputation evaluation algorithm.
