Reliability Calculation Method of Ship-to-air Missile Simulation Model

Simulation test plays an increasingly important role in missile test evaluation, and the reliability of simulation model determines whether simulation test can truly reflect the level of missile test evaluation. The model verification problem is formally described, and the model verification methods used in engineering are analyzed and summarized from two angles of feature comparison and error analysis. In order to solve the problem of independent model verification and credibility evaluation stage and complex credibility evaluation system construction, a credibility calculation method based on model verification data is proposed. Four parameters of ship-to-air missile simulation model are verified, and the results of two experiments are counted. According to the weight data of model credibility, the credibility of simulation model is calculated by the proposed credibility calculation method. The verification results of simulation model credibility calculation example show that the reliability calculation method based on model verification data is reasonable, the stages of model verification and credibility evaluation are unified, and there is no need to establish a complex credibility evaluation system. It is a simulation model credibility calculation with less computation and high universality.
