Abstract
Redundancy allocation problem (RAP), which aims to minimize the system total cost subject to some constraints on system reliability, represents an important problem in system design with many applications in areas such as electronic systems, power systems, telecommunication systems and manufacturing systems. In this paper, we extend RAP to a more generalized situation, First, the network topology is generalized, i.e., the components in the system can be of any logical relationship. Second, there exist chance constraints that the overall system reliability is required to exceed a prescribed value. We propose an efficient simulation optimization method. A numerical study shows that the proposed method can locate the optimal solution more efficiently compared to the existing methods.
