The Effects of Technical and Organizational Activities on Redundancy Allocation Problem with Choice of Selecting Redundancy Strategies Using the memetic algorithm

Abstract

Redundancy allocation problem is one of most important problems in reliability area. This problem involves with the suitable redundancy levels under certain strategies to maximizing system reliability under some constraints. Many changes have been made on this problem to draw the problem near to real situations. Selecting the redundancy strategy, using different system configuration are some of these changes. In this paper we considered the effects of technical and organizational activities on this problem and showed the difference between the system reliability with and without using these activities. In this paper we worked on a system containing s sub-systems connected serially together. Each sub-system contains parallel components that can be selected from different component types and all of each sub-system components must be the same. Because redundancy allocation problem belongs to Np. Hard problems, we used a new meta-heuristic algorithm called memetic competition algorithm for solving the presented problem and compared the result of this algorithm and other solving methods.
