An Algorithm to Determine the Spare Inventory Level for Repairable-Item Inventory System with Depot Spares

We consider the problem of determining the spare inventory level for a multiechelon repairable-item inventory system. Our model extends the previous results to the system which has an inventory at the central depot as well as at the several bases. We develop an algorithm to find spare inventory levels, which minimize the total expected cost and simultaneously satisfies a specified minimum service level. Comparisons of our algorithm with the simulation show that the algorithm is very accurate and efficient.
