A multi-item, multi-ship, multi-echelon repair system is considered. The model assumes that an overall budget constraint is imposed, the budget being required to fund the number of spares of each type of item, the repair expenditures over all repair echelons, and the amount of preventive maintenance or reliability for each item. It is assumed that the failures follow the Poisson distribution and that an infinite number of repair channels are available at each echelon, where the average repair time at the echelon depends upon the individual item. The model determines the optimal number of spares, the average repair times at each echelon, and the mean failure rates, so as to minimize the average shortages over all items and ships. Author
