摘    要:多层次系统(HS)的层次特征有助于故障覆盖.模块化不完全覆盖模型(MIPCM)阐明了HS的部件或模块跨层次的依赖性,依赖性大大增加了分析方法的复杂度.基于MIPCM,提出向上的模块化不完全覆盖模型(UMIPCM),更加清楚地阐明了层次与依赖性的对应关系.利用UMIPCM,借鉴SEA算法的思想,提出针对HS和MIPCM的自上而下的分离算法,这是一种高效的和集成的算法.最后通过案例说明了该分离算法的应用价值.

关 键 词:可靠性 多层次系统(HS) 简单有效的算法(SEA) 向上的模块化不完全覆盖模型(UMIPCM)

Abstract:The hierarchical nature of hierarchical systems(HS) aids in fault coverage.Modular imperfect coverage model(MIPCM) introduces the dependencies among components and/or modules across the different levels in the hierarchy that increases the complexity of solutions.Upon this,the upward MIPCM is obtained that more clearly represents corresponding relationship between the layer and the dependency.Based on this and the simple and efficient algorithm(SEA) idea,a top down separable algorithm is gained for the HS that is efficient and integrated.Finally,the application value of the separable algorithm is analyzed by a sample hierarchical system.
Keywords:reliability  hierarchical systems(HS)  simple and efficient algorithm(SEA)  upward modular imperfect coverage model(UMIPCM)
