摘要/Abstract

摘要： 在装备论证阶段，提出科学合理的测试性指标要求，可以有效指导测试性设计。目前鱼雷武器系统还缺乏有效的测试性参数定量分析方法，在综合比较现有各种测试性需求分析模型的基础上，提出了一种基于广义随机Petri网的测试性建模方法。通过构建鱼雷武器系统基层级维修保障流程的广义随机Petri网模型，得到状态可达图，并利用同构法，求解了测试性参数与可用度之间的关系；以可用度和平均故障修复时间为设计指标，对国外某型鱼雷的测试性参数进行了求解，并利用Petri网建模工具PIPE4.3.0软件进行了仿真分析，验证了模型和算法的有效性。

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.

Key words: torpedo, testability, availability, meantimetorepair, generalizedstochasticPetrinet, PIPE4.3.0
