Aiming at the problem of effect evaluation of weapon equipment simulation training, fuzzy theory is used to analyze it. From the reality of simulation training and computer automatic evaluation, the evaluation index system of weapon equipment simulation training effect is constructed. Based on the fuzzy analytic hierarchy process, the evaluation model of weapon equipment simulation training effect is established, and the specific evaluation method and steps are put forward. Taking a certain type of equipment decomposition and combination simulation training as an example, the application of the evaluation method and steps is carried out to verify its effectiveness. The results show that the evaluation method can provide a reference for the automatic evaluation of simulation training based on computer platform.
