Improvement on Fuzzy Synthetic Evaluation of ECM Effect
Yang Zhuo Wei · Radio Engineering of China · 2007
Because both the factors affecting the ECM and the relationship between them are fuzzy,the fuzzy synthetic evaluation method has an advantage on it.But,the difficulty of this method is to choose proper membership functions and weight values.Aiming at solving the problems that the membership function and weight value of each index in fuzzy synthetic evaluation of ECM effect can not be determined easily,this paper uses a cloud model to express the fuzziness and randomness of the evaluation results and realize the mapping between quantitative and qualitative relation so as to overcome the inaccuracy of the traditional membership function.Besides,it also modifies the consistency of the judgment matrix by the optimal transferring matrix based on AHP.Finally,the accuracy and effectiveness of this new method are proved through some examples.
