The design of a multi-item, multi-ship, multi-echelon repair system is considered. The model assumes an overall budget constraint is imposed, the budget being required to fund the number of spares of each type of item on board each ship, and also to fund the repair expenditures over all the repair echelons. The inputs into the model are the marginal costs of reducing the repair times at each echelon for each item, the costs of spares, the failure rates for each item on each ship, and the likelihoods that the repair of a failure of a given item on a given ship will necessitate work at a given echelon e.g., local, tender, depot. The model then determines the optimal provisioning in terms of the number of spares for each item on board each ship, and the average repair times at each echelon, by item, so as to minimize, within the budget constraint, an arbitrary weighting of the average deficiencies, i.e. backorders, over all items and ships.
