摘　　要：针对宝钢采购供应链系统中不同物料对应订货策略不同的问题,建立了物料的订购量模型;给出了物料安全库存设定的经验公式,并针对实际应用过程中有些量不能准确找到概率分布的问题,引入灰色模型对物料需求量、消耗量进行预测.通过对采购供应链系统中需求量的预测,给物料设定安全库存,采用不同物料的订购量模型,解决了采购供应链系统中的订货策略问题.实例表明,订货策略模型具有很强的实用性,为用户提供了较为实用的订货策略.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.
