Abstract: In the equipment demonstration stage, the scientific and reasonable testability index requirements can be put forward to effectively guide testability design. At present, there is no effective method for quantitative analysis of testability parameters of torpedo weapon system. Based on the comprehensive comparison of various existing testability requirements analysis models, a testability modeling method based on generalized stochastic Petri net (GSPN) was proposed. A grassroots level maintenance support GSPN model of the torpedo weapon system was constructed to get the reachable marking graph, and the relationship between the testability parameters and the availability was obtained by using the isomorphism method. Taking the availability A0 and mean time to repair MTTR as design indexes, the testability parameters of a foreign torpedo were solved. A Petri net modeling tool PIPE4.3.0 is used for simulation analysis to verify the effectivenesses of the model and algorithm.
