Overall fuzzy evaluation on operation efficiency of air defense fighting system

Air defense fighting system is an integrated large system, thus its overall evaluation is very complicated. On the basis of the comprehensive analysis on the operation efficiency of air defense system,the authors set up a quota system for the operation efficiency evaluation. The method of expert judgment was used for the quantitative evaluation on the factors that can not be analyzed quantitatively. Therefore a new operation efficiency evaluating method for air defense system is presented based on the fuzzy evaluation model.
