The Research of Dynamic and Comprehensive Evaluation of Interoperable Trust Based on Fuzzy Comprehensive Evaluation with Variable Weights

With the development of information technology, "Information Island" has become an obstacle to information resources sharing between cross-domains. Interoperability is the key technology to solve this problem. However, establishing a good trust relationship is a prerequisite for achieving interoperation between cross-domains. In order to strengthen the information resource sharing and collaboration between the entities cross-domains through trust, specific to the characteristic of interoperability-openness, dynamics, serviceability, autonomy, hierarchy and so on, an interoperable trust mechanism was studied in the paper: on the one hand, based on the background of organizational trust relationship, the qualitative and quantitative factors which affect interoperable trust were analyzed, and the trust evaluation index system was established; on the other hand, dynamic and comprehensive evaluation method for interoperable trust based on fuzzy comprehensive evaluation with variable weights theory were studied.
