Abstract: To solve the problem how to meet the needs of different materials in the Baosteel procurement and supply chain system via different ordering strategies, an ordering quantity model for these materials is developed with an empirical formula set for the safety stock. In the practical application process where some probability distributions can not be accurately found, the demand and consumption of materials are forecast by the gray model. With the demand of materials forecast, the safety stock is set in the procurement and supply chain system and, with the ordering quantity model applied to different materials, the problem of ordering strategy in the procurement and supply chain system is solved. Examples show that the ordering strategy model proposed here is of robust significance in application to users.
