In order to find a new lean methodology to improve the process of procurement management, this paper takes the warehouse in the manufacturing enterprise as a case to study. During lean consulting service provision, the firsthand material which the research work needs through the spot inspection was collected. To analysis the whole procurement process, the procurement value stream map based on the data collected was plot. Then the whole procurement process can be seen in the procurement value stream map, including making procurement plans, audit, procurement, transportation, inspection, storage, classifying and receiving materials. According to the procurement value stream map, wastes and non-value activities in the procurement process can be easily found and the improvement methods can be prompted. The contribution of this paper main reflects in two aspects: (1) the procurement value stream mapping (P-VSM) enriches improvement methodology of procurement management; (2) the P-VSM methodology enlarges the application scope of lean tools on one side.

为了找到一种新的精益方法来改善采购管理流程，本文以制造企业的仓库为例进行研究。在提供精益咨询服务期间，通过现场检查收集了研究工作所需的第一手材料。为了分析整个采购过程，绘制了基于收集到的数据的采购价值流图。然后，可以在采购价值流图中看到整个采购过程，包括制定采购计划，审计，采购，运输，检查，存储，分类和接收物料。根据采购价值流图，可以轻松地发现采购过程中的浪费和非价值活动，并可以提出改进方法。本文的贡献主要体现在两个方面：（1）采购价值流图（P-VSM）丰富了采购管理的改进方法。（2）P-VSM方法论一方面扩大了精益工具的应用范围。
