Abstract: A mathematic model of survival probability of navel ships is established for integrated anti-torpedo simulation evaluation and confirmation of suspended depth charge. The sample values of survival probability are calculated from the sample data of interception probability output of simulation system. In view of the characteristics of high dimension and large number of survival probability samples,an idea of applying multiple hypothesis test to simulation system validation is proposed. A power model for evaluating test efficacy and a model for calculating p-value of survival probability samples are established,and the steps to solve the key indicators in the model are given. The important evaluation index values of the simulation system were obtained,and the system was evaluated and confirmed. Research results show that the multiple hypothesis test is more strict for the confirmation of simulation system,and it is better than traditional hypothesis test in controlling the first kind of errors.
