摘　　要：针对钢铁企业采购物资种类多、采购环境复杂的特点,采用Kraljic模型从收益影响和供应风险两个维度进行物资分类,建立钢铁企业物资分类指标体系.为了避免物资分类指标综合评价过程中主观性的影响,提出一种基于数据包络分析(Data Envelopment Analysis,DEA)属性的线性规划方法,用以计算综合指标评分.以钢铁企业L为案例,得出几种常见物资的采购类别,并制定相应的采购策略以降低采购难度及采购成本.There are various kinds of raw materials in steel enterprise and the purchasing environment is compli- cated, so an index system for raw materials classification is established by using Kraljic model from the aspect of profit impact and supply risk. In order to avoid the subjective effect, a linear programming with data envelopment analysis character is put forward to calculate the comprehensive value of all indices. From the case of steel enter- prise L, several ordinary materials are divided into four purchasing categories and corresponding purchasing strat- egies are made for purchasing easily and cost saving.
