Purpose: In this paper, we consider a spare parts allocation problem for multi-level systems with two-echelon repair systems. The system consists of multi-units (components and modules) and has a multi-level structure. The (S-1, S) inventory policy is considered to order spare parts.
Methods: We determine the line replaceable units (LRUs) and these maximum spare parts storage levels S in echelon sites that minimize the life cycle cost and satisfy the target system availability. The near-optimal solutions are obtained by a genetic algorithm and simulation. The genetic algorithm is used to generate alternative solutions and simulation is used to evaluate the alternative solutions.
Results: We investigate the effect of parameters on the near-optimal solutions in numerical examples. The results show that as the target system availability increases, the level of LRU is increased because shorter replacement time leads to increase the system availability.
Conclusion: This study shows that the variation of target system availability affects the results of the near optimal solutions. For further studies, we will consider inventory policy of depot (s, S) and the repair of failed LRU.
