Abstract: In order to solve the large deviation between the purchasing demand and the actual purchase of telecom operators, and optimize the purchasing cost and the purchasing efficiency, the procurement demand management of telecom operators is studied and a demand management optimization scheme based on BOM is constructed to establish the purchasing demand forecasting model Taking a telecom operator branch as an example, purchasing demand forecasting model and data of transport network, the wired access network and wireless network are given and the accuracy of the model is verified by historical data The model is flexible and easy to use, and has practical significance for telecom operators′ purchasing process optimization and cost control

Key words: procurement demand management, demand forecasting model, telecom operator procurement, category management
