On a class of multiple failure mode systems
研究了一类多状态可靠性结构，其中组件性能水平无需排序，允许组件经历多种故障模式，并给出了精确可靠性公式、边界和渐近结果，通过数值实验验证了两种经典系统的扩展。
The primary objective of this work is to introduce and perform a detailed study of a class of multistate reliability structures in which no ordering in the levels of components' performances is necessary.In particular, the present paper develops the basic theory (exact reliability formulae, reliability bounds, asymptotic results) that will make it feasible to investigate systems whose components are allowed to experience m ≥ 2 kinds of failure (failure modes) and their breakdown is described by different families of cut sets in each mode.For illustration purposes, two classical (binary) systems are extended to analogous multiple failure mode structures and their reliability performance (bounds and asymptotic behaviour) is investigated by numerical experimentation.
