Abstract

In this paper, a reliability model is constructed for a weighted performance sharing phase mission system. The system comprises N components and a common bus, with each component having multiple deteriorated states. Each state has various performance levels influenced by external factors. The system operates over L phases, distinguished by the weight and demand of the components and the required quality of the system. To remain operational, the components must meet their respective demands while maintaining the system quality. When the system fails, performance is redistributed among the components via the common bus to restore operational status. An optimum allocation algorithm is developed to share performance efficiently using minimal transmission capacity. The instantaneous availability of the system in each phase is determined using a combination of the Markov process and the UGF technique based method. A numerical example of a hybrid wind-solar power distribution system is presented to illustrate valuable findings using the proposed method.

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.
