A reparable-item inventory system has two sources of items to meet demands from the procurement of new items, and from the repair of damaged or failed items. Further, the system contains two distinct inventories, one containing procured and repaired ready-for-issue items and the other containing those failed items awaiting repair. This thesis develops an approximate model of this general system assuming that the demand rate and return rate of failed items are probabilistic. A periodic review policy is assumed for procured items, and inductions of batches of failed items into repair are assumed to take place at regularly scheduled intervals of time. The model is structured as a single coordinated inventory system instead of two separate systems, one of procured items and one of repaired items. The optimal review period and order up to level for procured items are determined, along with the optimal time between repair batch inductions. Author
