Multi-Echelon Integrated Inventory Control Strategy of Equipment Spare Parts

Inventory control strategy of spare parts is an effective way to improve equipment support efficiency and scientific and reasonable inventory policy can make spare parts availability reach the upper limit. Multi-echelon integrated inventory control strategy of equipment spare parts is studied. Three-level integrated inventory control model consisting of rear warehouse, equipment using units and spare parts supplier is established according to the architecture and control program of multi-echelon joint inventory. The algorithm of solving the proposed model is analyzed and a numerical example is provided. The proposed equipment spare parts inventory model can improve inventory quality to a certain degree and decrease the contradictions between inventory and maintenance. The correctness and effectiveness of the proposed model are verified by the example, which provides an effective model for equipment spare parts inventory.
