Abstract

This paper is a study on comparison between coherent systems with independent and heterogeneous components. Specifically, we consider 3-component coherent systems composed of two different types of components where we assume that component lifetimes follow the well-known proportional hazards model. We stochastically compare such systems under different situations and based on some assumptions on the parameters of proportionality.

关于具有两种不同类型组件的相干系统的随机比较

摘要

本文研究了具有独立和异构组件的相干系统之间的比较。具体来说，我们考虑由两种不同类型的组件组成的 3 组件相干系统，其中我们假设组件的寿命遵循众所周知的比例风险模型。我们在不同情况下随机比较这些系统，并基于对比例参数的一些假设。
