Joint importance of multistate systems
Importance measures in reliability engineering are used to identify weak areas of a system and signify the roles of components in either causing or contributing to proper functioning of the system. Traditional importance measures for multistate systems mainly concern reliability importance of an individual component and seldom consider the utility performance of the system. This paper extends t...
متن کاملOn the Joint Reliability Importance for k-out-of-n Systems
In this paper, the concept of joint reliability importance (JRI) of two or groups of components in a coherent system with independent components have been studied. The JRI is defined as the rate at which the system reliability improves as the reliabilities of the two or groups of components improve. Generally, the sign and the value of the JRI represent the type and the degree of i...
متن کاملJoint Structural Importance in Consecutive-k Systems
The joint structural importance (JSI) is an important measure of how two components interact in contributing to the system reliability. The value of JSI is positive (negative) if and only if one component becomes more important (less important) when the other works. A consecutive-k-out-of-n system is a linear arrangement of n components such that the system is failed if and only if some consecu...
متن کاملMeasures of component importance in repairable multistate systems - a numerical study
In [10] dynamic and stationary measures of importance of a component in a repairable multistate system were introduced. For multistate systems little has been published until now on such measures even in the nonrepairable case. According to the Barlow-Proschan type measures a component is important if there is a high probability that a change in the component state causes a change in whether or...
متن کاملMeasures of Component Importance in Nonrepairable and Repairable Multistate Strongly Coherent Systems
In Natvig and G̊asemyr (2009) dynamic and stationary measures of importance of a component in a binary system were considered. To arrive at explicit results the performance processes of the components were assumed to be independent and the system to be coherent. Especially the Barlow-Proschan and the Natvig measures were treated in detail and a series of new results and approaches were given. Fo...
