For the automotive industry, especially the automobile parts industry, the reasonable control of inventory and transportation logistics cost can effectively increase the profit of the enterprises。 In China has just begun the research on supply chain logistics management, on the auto industry supply chain logistics integration of the theory are not much。 After entering the 21st century, China's auto industry has been facing globalization challenge, in such a grim situation, how to grasp logistics and supply chain management theory, development and innovation and practical logistics chain system, strengthen the viability of the domestic automobile enterprises, is very necessary。

Based on the actual auto parts enterprises as the background, analysis of the inventory problem of product production line may appear in the actual process, to explore how to effectively solve these problems。 Firstly, introduces the basic theoretical knowledge of inventory and transportation。 In the description of the concept of inventory, inventory, inventory, inventory cost classification and the importance of inventory management; in transport, explains the classification and analysis of the transportation cost between inventory and transportation link, reduce the cost of transportation for them。 Later, recommends that companies take the initiative to ask the real needs of customers, and then according to their own actual situation to formulate reasonable inventory plan, which recommended the Vendor Managed Inventory (VMI) according to the technology or theory, reasonable assumptions, optimization model is established about inventory and transportation。 And the transport problems are discussed and put forward。 Milk-run mode to save transportation costs。

 Key words   inventory, transportation, VMI technology, milk-run model, transportation and inventory optimization。

1。1  论文的选题背景

近来，汽车产业的热度虽然有些减缓，但仍然十分有发展前景。在今后的几十年，会有越来越多的跨国公司进入中国市场，会将更多的产品与技术带到中国并通过物流来降低它的供应链成本。

中国汽车行业如果想要超过日本，敢上欧美，必须要开拓视野，不仅仅局限于国内市场，要大胆出口自己的产品。在汽车的发展中，如何获得更大的市场份额即更多的利益，不仅仅要技术创新，质量保证，还有合理的去减少不必要的资金损耗，合理的控制物流成本就是一个十分不错的方法。
