关于相互竞争的风险和退化过程

On competing risk and degradation processes

Nozer D. Singpurwalla

摘要:

莱曼的思想概念的依赖性产生了深远的影响数学理论的可靠性。本文的目的有两个方面。第一个是说明“潜在危险”的概念如何能够解释生命周期之间相互依赖的原因。第二个是提出了一个总体框架,在这个框架下,目前讨论的两个问题,在可靠性和生存分析,涉及相互依赖的随机过程,可以有意义地通过一个潜在的危险的概念来解决。第一个问题涉及到一个项目在多个相互依赖的风险下的动态设置中的失败。第二个涉及到评估一个项目的生命长度在可观察的替代品或标记的存在。这里的设定也是动态的,标志的作用类似于多个时间序列中的领先指标。

英文摘要:

Lehmann's ideas on concepts of dependence have had a profound effect on mathematical theory of reliability. The aim of this paper is two-fold. The first is to show how the notion of a ``hazard potential'' can provide an explanation for the cause of dependence between life-times. The second is to propose a general framework under which two currently discussed issues in reliability and in survival analysis involving interdependent stochastic processes, can be meaningfully addressed via the notion of a hazard potential. The first issue pertains to the failure of an item in a dynamic setting under multiple interdependent risks. The second pertains to assessing an item's life length in the presence of observable surrogates or markers. Here again the setting is dynamic and the role of the marker is akin to that of a leading indicator in multiple time series.
