In most studies, mathematical laws are used to forecast, without enough consideration of the actual operation of equipment and the fact that the accuracy of spare parts demand forecasting is not high, which cannot adapt to the new characteristics of complex equipment use environment and fierce market competition in modern enterprises. The digital twin model can be used to forecast the demand for spare parts more accurately and guide modern enterprises to carry out accurate support. By analyzing the current spare parts demand of modern enterprises, the paper puts forward the forecasting ideas of spare parts demand based on the digital twin model by using the digital twin model of equipment maintenance management in modern enterprises. In the digital twin model, the theoretical demand forecasting model of spare parts based on life distribution of replaceable units is introduced, and the sensitivity coefficient system of spare parts demand of replaceable units to operation and environment is constructed. The digital twin model is used to feedback train the sensitivity coefficient to obtain the reliable spare parts demand rules. Based on the theoretical demand and sensitivity coefficient of spare parts, the forecasting method of spare parts demand is given, and the spare parts demand forecasting model is established. Through case analysis, the feasibility and accuracy of the forecasting model are verified. <\/jats:p>","DOI":"10.1142\/s1793962322500453","type":"journal-article","created":{"date-parts":[[2022,2,9]],"date-time":"2022-02-09T03:55:30Z","timestamp":1644378930000},"source":"Crossref","is-referenced-by-count":7,"title":["Spare parts demand forecasting method of modern enterprises based on digital twin model"],"prefix":"10.1142","volume":"13","author":[{"given":"Shuai","family":"Wang","sequence":"first","affiliation":[{"name":"Department of Equipment Command and Management, Shijiazhuang Campus, Army Engineering University of PLA, No. 97 Heping West Road, Xinhua District, Shijiazhuang, Hebei 050000, P.
