Abstract:

In order to resolve the validation problem of the simulation models with iteration operation, and implement traceable credibility evaluation, based on the explanation of the looped validation and credibility synthesis problem, the building method of factor space (index system) for simulation model’s validation is presented, a theorem of validation for simulation models with iteration operation as well as a validation method are put forward, and the method is applied to calculate a quantitative credibility of a flying vehicle model, locate the defect nodes which induce the deficiency of model credibility, and prove the efficiency of the method.
