Abstract

After systematic analysis of hazard factors of network sureness and evaluation process, a quantitative sureness evaluation method is presented based on fuzzy number operations. First of all, both the fuzziness of the indices and the uncertainty of weight determination are considered. The grades of fuzzy language variables are given, and the opinions of multi experts are integrated to triangular fuzzy numbers. Then comprehensive fuzzy evaluation is made using the operation rules defined on the triangular fuzzy number. Finally, by using fuzzy number ranking method, the evaluation result is defuzzified and the hazard grade is determined. An illustrative example is given to show the effectiveness and validity of this method.
