Method and Application Research on Fuzzy Comprehensive Evaluation Based on Cloud Model

Instead of fuzzy membership function,by the theory of backward cloud generator and the algorithm of cloud we evaluate the fuzzy comprehensive system with the cloud model,which has the quality of fuzzy,random and statistic.Finally,with the supervision and testing data of food safety,we compare the method of cloud model with the normal method of fuzzy membership function,which proves that the cloud model has more advantages than the normal method.
