Considering the increasingly high attention to quality, promoting the reliability of products during designing process has gained significantimportance. In this study, we consider one of the current models of the reliability science and propose a non-linear programming model forredundancy allocation in the series-parallel systems according to the redundancy strategy and considering the assumption that the failurerate depends on the number of the active elements. The purpose of this model is to maximize the reliability of the system. Internalconnection costs, which are the most common costs in electronic systems, are used in this model in order to reach the real-worldconditions. To get the results from this model, we used meta-heuristic algorithms such as genetic algorithm and simulation annealing afteroptimizing their operators’ rates by using response surface methodology
