This thesis represents the most recent step in the development of a new wholesale level repairable item inventory model for the Navy. Distinguishing features of the process by which repairable items are managed in the Navy are batching of both repair and procurement orders and a specific repair assessment policy which sees repairable items enter repair agencies in batches but leave as single items. Approximate steady state probability distributions for inventory position and net inventory are developed and these are extensively tested against simulation results. Graphical analysis and testing using non parametric methods suggest that the approximations developed closely resemble the distributions obtained via simulation.
