摘要：
Spare parts are the material basis of equipment operation and maintenance, and spare parts procurement usually takes a large share of equipment lifecycle cost. The traditional methods of calculating the spare parts demand volume only consider the requirements of corrective maintenance, and cannot be used to calculate the spare parts demand volume by considering preventive maintenance. A model of calculating the spare parts demand volume based on age replacement policy is proposed. A discrete algorithm for the model is presented. An example analysis is carried out to verify the applicability and effectiveness of the proposed model. The proposed model is compared with traditional calculation model. The research results show that the proposed model can be used to improve the accuracy of calculating the spare parts demand volume. It can be also used to calculate the spare parts demand volume for any long planning horizon and analyze the spare parts cost in equipment lifecycle process. © 2016, Editorial Board of Acta Armamentarii.
