基于模糊粗糙集理论的地空导弹武器装备故障诊断研究

Study of Fault Diagnosis of Surface-to-air Missile Weapon Equipment Based on Fuzzy-rough Sets

针对在武器装备故障诊断中对连续属性离散化存在的"尖锐边界"问题,给出了一种基于模糊粗糙集理论的改进故障诊断方法.对模糊等价关系下粗糙集模型进行了描述,并在此基础上给出了正域、依赖度、确定性因子等概念,详细分析了此故障诊断的具体实施步骤,最后通过算例验证了该方法的可行性.

The technology of displacement ventilation of surface to air missile weapon equipment based on fuzzy-rough sets is described in order to solve the problem of sharp boundary in consecutive attributes dispersing.The model of rough sets under fuzzy equivalant relation is investigated systemically,and the conceptions of positive field,the depend-degree and so on are presented.The basic processes of displacement ventilation of surface to air missile weapon equipment based on fuzzy-rough sets are analyzed particu...
