Aiming at the problems of imperfect performance evaluation indexes and difficulties in computer evaluation of existing simulation training system,a simulation training performance evaluation model based on improved analytic hierarchy process (AHP) is proposed.Starting from the actual operation of long-range rocket weapons and equipment,a simulation training performance evaluation system is constructed,which takes accuracy,proficiency,influence and mental outlook as evaluation indexes.By adopting the improved analytic hierarchy process,the inter-class coefficient and intra-class coefficient are introduced to optimize the ratio of experts,and the mathematical model of simulation system training performance evaluation is established.The effectiveness of the model is verified by the comparative analysis of the simulation training system,and the final results of the trainees are obtained.The results show that this method can quantify the evaluation index and decompose the final score,which has certain reference value for improving the efficiency of performance evaluation of equipment simulation system.
