Subjective Trust Evaluation Model Based on Fuzzy Reasoning

In this paper, taking subjective trust as the background in the open network system, the subjective trust is analyzed. It shows the subjective trust has the subjectivity, uncertainty and randomness etc., which shows fuzziness. Based on the fuzzy reasoning theory, the subjective trust evaluation model based on fuzzy reasoning is studied and proposed by the aid of local information and the associated analysis and confirmation of this model is discussed in this paper. In this paper, we concentrate on studying the rules and reasoning procedures of this subjective trust evaluation model, the evaluation of subjective trust is solved finally. Through simulation, the feasibility and the rationality of this subjective trust evaluation model are further confirmed. At the same time, this model proposed in this paper enlightens also a new way for this subjective trust evaluation model of current complex network system.
