Research on Improved Fuzzy Synthetic Evaluation Model in Exercise Efficiency Evaluation of Command Information System

In order to evaluate the exercise efficiency of command information system in complex electromagnetic environments,establish the command information system combat training effect evaluation index system base on the analysis of the factors what impact the system Effectiveness.Aiming at the problems of traditional fuzzy synthetic evaluation model in practical application,which are much subjective as calculating weight of index and do not make full use of all information,the following methods were improved:using the principal component analysis to replace the Experts to to calculate the weight of index,using weighted average operator to replace classical big or small operator.Finally,the results show that the method can realize the quantitative analysis of efficiency evaluation,which prove a reference foundation to improve of the quality of training.
