Redundancy technique is notorious as a way to augment the reliability and accessibility of non-reparable systems, but for repairable systems, a different factor is receiving important called as the number of continuance resources. In this study, accessibility optimization of series-parallel systems is modeled by using Markovian process by which the numeral of continuation resources is positioned into the purpose model under constraints such as cost, weight, and volume. Due to difficulty of the model as nonlinear indoctrination, solving the model by profitable software is not possible, and a straightforward heuristic method called as imitation annealing is applied. Our main giving in this study is correlated to the expansion of a new availability model consider a new decision variable called as the number of continuance resources. A numerical replication is solved and the results are shown to display the proficient of the method.
