Abstract Mission success probability (MSP) is an important measurement to evaluate the performance of phased-mission systems (PMSs). The PMSs consist of some subsystems in series, and each subsystem is made of some k-out-of-n structures with repairable component modules. Adjusting the reliability and maintainability of components can improve the MSP of repairable PMSs. Therefore, the objective of MSP optimization for PMSs with repairable component modules is to maximize the MSP considering the c...
Abstract Mission success is an important criterion to measure the performance of phased-mission systems, which is the ability of systems to finish the work successfully. Activating the spare parts takes little time, which can reduce the maintenance time while performing the mission. Moreover, adding the spare parts also can ensure the mission to complete with higher success probability. This paper puts forward an integrated modeling method to evaluate the mission success probability for repairab...
Component assignment problem is a common challenge of reliability optimization, which is a non-deterministic polynomial hard problem widely used in the linear consecutive k-out-of-n systems. In con...
The reliability optimization problem arises along with the increasing demands for products’ performance in practical engineering. Importance measures are capable of selecting critical components to gain the greatest improvement in system reliability with the constraint of maintenance cost. The characteristics of importance measure for four kinds of typical systems are discussed to illustrate the usage of importance measure in the practical reliability optimization. A reliability optimization mod...
For the reliability analysis of complex equipment system, one of the key objectives is that the equipment can complete the specified mission as expected. First of all, this article presents the analysis method of mission success importance for a multi-state k-out-of-n repairable system based on multi-state multi-valued decision diagram as well as the implementation procedure. Second, the engineering significance of mission success importance for a multi-state repairable 2-out-of-3 system is disc...
The circular-consecutive -out-of-: system (Cir/Con//: system) usually consists of components arranged in a circle where the system fails (works) if consecutive components fail (work). The optimization of the Cir/Con// system is a typical case in the component assignment problem. In this paper, the Birnbaum importance-based genetic algorithm (BIGA), which takes the advantages of genetic algorithm and Birnbaum importance, is introduced to deal with the reliability optimization for Cir/Con// system...
