摘要

本文研究了部件级和系统级多主动冗余的随机比较问题。在假设所有成分都是统计相关的基础上，在完全匹配和不匹配的情况下，我们分别在风险率、反向风险率和似然比的顺序上给出了一些有趣的比较结果。在构件级和系统级得到了系统相对老化的两个比较结果。给出了几个数值算例来说明理论结果。

Orderings of component level versus system level at active redundancies for coherent systems with dependent components

This paper investigates the issue of stochastic comparison of multi-active redundancies at the component level versus the system level. Based on the assumption that all components are statistically dependent, in the case of complete matching and nonmatching spares, we present some interesting comparison results in the sense of the hazard rate, reversed hazard rate and likelihood ratio orders, respectively. And we also obtain two comparison results between relative agings of resulting systems at the component level and the system level. Several numerical examples are provided to illustrate the theoretical results.

期刊介绍： The primary focus of the journal is on stochastic modelling in the physical and engineering sciences, with particular emphasis on queueing theory, reliability theory, inventory theory, simulation, mathematical finance and probabilistic networks and graphs. Papers on analytic properties and related disciplines are also considered, as well as more general papers on applied and computational probability, if appropriate. Readers include academics working in statistics, operations research, computer science, engineering, management science and physical sciences as well as industrial practitioners engaged in telecommunications, computer science, financial engineering, operations research and management science.
