碩士 / 元智大學 / 工業工程與管理學系 / 93 / Military equipment supply chain encompasses network of customers and suppliers, and deal with a wide variety of items. Demand inside the network is generated at the unit level at a specific base. The demand from the bases in aggregated to upstream service depots. The multi-echelon maintenance supply chain often results in unnecessary cost and delay times, as well as low equipment availability at the bases.
Risk pooling is a new inventory management concept that reduces the demand variability by sharing the inventory across different locations. This reduction in variability allows a decrease in inventory cost and increase the fulfillment rate. Direct shipment strategies exist to bypass the middle echelons. The supplier delivers goods directly to the bases to reduce the lead time. This research assesses the effect of applying these two commercial practices to the multi-echelon military maintenance supply chain, and then evaluates the results by using a simulation model.
In this research, we use SIMSCIPT II.5 to develop a simulation model of the military equipments. In this model, there are six independent bases supported by three intermediate units and a single depot. We compare three inventory strategies: the current operation, risk pooling strategy, and risk pooling plus direct shipment. Our simulation results show that the risk pooling plus direct shipment strategy can reduce the system cost by more than 46 million NT dollars (2.75%) and increase the equipment availability by 2.72%.
