Abstract

The invention relates to a method for evaluating the risk of a simulation system based on fuzzy FMEA, in particular to a method for evaluating the risk of the simulation system through fuzzy FMEA. The method aims to solve the problems that an existing method for evaluating the risk is unreasonable in cost allocation and evaluation, an evaluation result cannot meet requirements, and qualitative evaluation is based on opinions and judgment of people. The method includes the steps that firstly, the risk of the whole simulation system is preliminarily evaluated based on fuzzy FMEA, and then a fuzzy result is obtained; secondly, evaluation cost of the whole simulation system is estimated; thirdly, a calculation model of the risk and the cost of the whole simulation system is built; fourthly, the relation between fuzzy linear cost and the risk of the whole simulation system is evaluated, a fuzzy linear programming model of an evaluation solution is built, and then the final whole risk evaluation result is obtained. The method is applied to the field of risk evaluation.
