An efficient simulation optimization method for the generalized redundancy allocation problem

摘要

Highlights?A new simulation optimization method called PSORO is developed.?Due to specially-designed mechanisms, PSORO can solve GRAP effectively and efficiently.?PSORO is proved to possess the desirable convergence.?Numerical experiments show that the performance of PSORO is promising.AbstractThe redundancy allocation problem (RAP) is concerned with the allocation of redundancy that maximizes the system reliability subject to constraints on system cost, or minimizes the system cost subject to constraints on the system reliability, has been an active research area in recent decades. In this paper, we consider the generalized redundancy allocation problem (GRAP), which extends traditional RAP to a more realistic situation where the system under consideration has a generalized (typically complex) network structure; for example, the components are connected with ea
