摘　　要： F公司是一家为东风日产提供汽车零部件的供应商,采用了同步供货的供货方式准时将东风日产所需要的零部件配送其指定的总装线边。为了实现这种小批量多品种多频次的供货方式,F公司建立了看板为基础的JIT拉动式生产体系,利用成品库存超市的取货看板的来拉动生产补货、以零部件的取货看板来拉动原材料的订购,并以客户的需求预测及生产与运输的提前时间按照MRP的方法分别设定成品与原材料的库存数量与批量。然而这种库存控制策略只强调了不能缺货,并没有考虑库存与运输成本的整体优化下的经济生产批量,在这种情况下库存水平居高不下,大量的资金积压在仓库。通过对成品和原材料的库存水平与库存成本进行优化,设定合理的成品与原材料的经济生产批量,这有利于减少公司的库存资金,增加现金流,应对金融危机有积极的意义。 本文利用精益生产中价值流图的方法分析F公司为东风日产同步供货的生产与供应流程,分析了在满足准时配送条件下同步供货供应商的生产、库存和运输过程,重点对成品和原材料库存联合优化进行了详细研究,建立了集成化的库存模型,提出了在准时制生产模式下的库存优化方案。 F company is a tie1 supplier of DFL. As DFL’s request, F company implement synchronized supply system to provide components to assembly line of DFL JUST-IN-TIME. In order to achieve this kind of supply method of small lots and high frequency, F company setups a JIT pull production system based on KANBAN. Component production KANBAN of finished goods supermarket is used to start production. And material withdraw KANBAN is used to trigger replenishment of raw material. And MRP also is used for master production plan and raw material purchase. But this kind of inventory control policy only focuses on no shortage; never consider the cost and efficiency of inventory system. So, it causes high inventory level and hold lots of money in store. Optimal on inventory level and cost, will be helpful to reduce the operation cost, increase cash flow, and positive to economic crisis. This paper uses the value stream analysis tool of lean manufacturing, to analysis the synchronized supply system between F Company and DFL, to analysis the process of material flow. And focus on optimal of integrated inventory, make a model for integrated inventory, and raise some ideas for this JIT system.
