Research on Configuration Optimization of Multi-echelon Inventory Based on Component Commonality

In view of the repairable spare parts, considering the actual situation that component commonality exists in warship equipment, the requirements of spare parts and sites in all levels are modified. A multi-echelon configuration model of common parts based on METRIC theory is established. The marginal optimization algorithm is used to obtain spare parts. The optimal supply support schemes prove that this model improves the model evaluation accuracy and reduces the total configuration cost under the premise of meeting the requirements of support index, which provides a theoretical basis and decision support for the current equipment to promote the use of component commonality. Keywords—spare part; component commonality; multi-echelon configuration strategy
