چکیده

Redundancy allocation problem is one of the most important problems in reliability area. this problem involves the suitable redundancy levels under certain strategies to maximize system reliability under some constraints. however, it has undergone many changes to come closer to the real situations. selecting the redundancy strategy and using different system configuration are some of these changes. in this paper, we studied the effects of technical and organizational activities on this problem and showed the difference between the system reliability with and without using these activities. also, we worked on a system containing s subsystems connected serially. each subsystem contains ni ; i = 1; 2; : : : ; s parallel components that can be selected from mi ; i = 1; 2; : : : ; s different component types and all subsystem components must be identical. because redundancy allocation problem belongs to np. hard problems, we used a new metaheuristic algorithm called memetic competition algorithm for solving the presented problem and compared the results of this algorithm with other solving methods.
