基于二维决策图分析单调关联系统的“标签”性质

Based on Binary Decision Diagram to Analysis Signatures Properties of Coherent System

"标签"理论最初作为一个有用的工具来分析部件寿命是独立同分布的单调关联系统。萨马涅戈和纳瓦罗等人通过得到划分事件的概率和对事件概率求置换的方法,定义系统部件寿命是独立同分布时的"概率标签"和"结构标签"。而对于部件不是独立同分布时,提出二维决策图法来分析"标签"性质。结合二维决策图的可视化以及部件的状态概率进一步地得到部件不是独立同分布情形下的"标签"定义。

The theory of signatures originally emerged as a useful tool in the analysis of coherent systems with components having independent, identically distributed lifetimes. Samaniego and Navarro et al defined probability-signature and structure-signature by means of getting the probability of the partition events and seeking the permutations of the proba- bility of the events which the system components having independent, identically distributed lifetimes. For components are not independent and identically distributed, this chapter proposed the binary decision diagram method to analysis the signature. Combining visualization of binary decision diagram with state probability of components, this chapter got the definition of signature which the system components not having independent, identically distributed lifetimes.
