【摘要】 为解决复杂系统故障诊断问题,利用面向对象思想、高级Petri网技术、模糊理论以及概率理论,建立了一种描述复杂系统故障关系的模型———FPPNS,介绍了模型涉及的对象类,给出了模型的诊断推理过程。该模型应用于发射装置的故障诊断,取得了良好的应用效果。用实例说明了模型的应用方法。更多还原

【Abstract】 In order to solve the problem of complex system fault diagnosis, a model was presented to depict fault propagation and analysis of complex system, which uses object-oriented concepts, high-level Petri nets, fuzzy theory and probability theory. The object classes and consequence process of the model were introduced. The applications of the model in emission equipment proves the practicability of the model. Finally, the applied means were illuminated by a simple example.更多还原
