Abstract

Non-coherent Multi-State System (MSS) is a special case in the point of view of reliability analysis and needs special methods for its reliability quantification. The specificity of this system behavior is a possibility of its performance degradation depending on the improvement of the functioning of its component, or its performance improving depending on the component work degradation/failure. Non-coherent system, mostly investigated for Binary-State System (BSS) where the system and its components have only two performance levels as functioning and failure. The case of MSS where the system and its components can have more than only two performance levels is studied fragmentarily. In this paper, a new method for importance analysis of non-coherent MSS is proposed. This method is based on the use of Logical Differential Calculus for the definition and calculation of Importance Measures (IM). In particular, the Structural Importance and Birnbaum’s Importance measures are defined and considered for a non-coherent MSS. These measures allow us to investigate the influence each of the system components has on its behavior, taking into consideration the specifics of a non-coherent MSS.

非相干多态系统的重要性分析

非相干多态系统（MSS）在可靠性分析中属于特例，需要采用特殊的方法对其进行可靠性量化。这种系统行为的特殊性是其性能下降的可能性取决于其组件功能的改善，或其性能提高取决于组件工作的退化/故障。非相干系统，主要研究二进制状态系统（BSS），其中系统及其组件只有两个性能水平，即功能和故障。对系统及其组件可以具有两个以上性能级别的MSS进行了零碎的研究。本文提出了一种新的非相干MSS重要度分析方法。该方法基于逻辑微分法对重要性测度（IM）的定义和计算。特别是，结构重要性和伯恩鲍姆的重要性措施定义和考虑了一个非连贯的MSS。这些措施使我们能够研究每个系统组件对其行为的影响，并考虑到非相干MSS的具体情况。

期刊介绍： Elsevier publishes Reliability Engineering & System Safety in association with the European Safety and Reliability Association and the Safety Engineering and Risk Analysis Division. The international journal is devoted to developing and applying methods to enhance the safety and reliability of complex technological systems, like nuclear power plants, chemical plants, hazardous waste facilities, space systems, offshore and maritime systems, transportation systems, constructed infrastructure, and manufacturing plants. The journal normally publishes only articles that involve the analysis of substantive problems related to the reliability of complex systems or present techniques and/or theoretical results that have a discernable relationship to the solution of such problems. An important aim is to balance academic material and practical applications.
