网络制造环境中信任评估机制的研究

Trust Evaluation in Networked Manufacturing Environment

在网络制造环境中,各种恶意的、虚假的、不真实的信息阻碍了制造服务提供主体与制造服务消费主体之间协作关系的构建。在分析分布式网络制造环境中服务提供主体与消费主体之间的信任的基本概念以及特征的基础上,分别建立了针对直接交互信息的直接信任预测模型以及针对非直接交互信息的信誉计算模型,并在此基础上给出了信任的综合计算模型。为了说明该模型的有效性,采用假设检验的方法对模型进行了验证。

Building up collaborative relationship between manufacturing service provider and manufacturing service consumer was impeded by malicious, fake, and truthless information in networked manufacturing environment. A direct trust computing model was proposed according to the direct interaction and a reputation computing model in terms of the indirect interaction between service providers and service consumers. It was based on the analysis of the concepts and characteristics of trust between service entities and consumer entities. Then a trust comprehensive computing model was presented. Lastly the hypothesis testing was used to confirm the validness of the model.
