1、论从整个供应链的角度管理库存（On the management of inventory from the perspective of the whole supply chain）On the management of inventory from the perspective of the whole supply chainAbstract: on the basis of discussing the traditional inventory management mode and its existing problems, the supply is put forwar
2、dThis paper introduces two supply chain inventory management models and their advantages.Keywords: inventory management; vendor managed inventory; joint inventory managementInventory enterprises play a very important role in the process of operation. Inventory can improve customer serviceLevel, it a

The existence of inventory not only ensures the smooth progress of sales activities, but alsoIncreased actual sales. Inventory

However, inventory cos

Therefore, inventory management research has important economic significance, supply chain in
6、ventory managementManagement is an important part of supply chain management, which optimizes the inventory of the whole supply chainHigh efficiency of the whole supply chain.2 traditional inventory management and Bullwhip effectThe traditional inventory management model is mainly based on single en
7、terprise inventory management, is the enterprise of each node aloneEstablish management inventory, from the perspective of maximizing the enterprises own interests, by determining the order point and order quantity to seek dropLow inventory, reduce shortage, reduce the risk of demand uncertainty. Th
8、e traditional inventory management mode makes the supply chain more efficientThe lack of information communication among enterprises, the degree of cooperation between enterprises is very low. Thus, the Bullwhip effect is produced.The Bullwhip effect is a phenomenon of demand variation amplification
9、 in the supply chain, and it is the information flow from the final customerWhen the end is delivered to the original supplier, it can not effectively realize the sharing of information, making the information distorted and graduallyAmplification leads to the increasing fluctuation of demand informa

Specifically, retailers are able to copeThe increase of customer demand is often put on the forecast quantity of historical and realistic salesAfter the big order to wholesalers, wholesalers and for the same consideration, increase the amount of orders. So, thoughHowever, the fluctuation of cu
11、stomer demand is not large, but the actual demand is enlarged step by step by adding orders at different levels. For example,If a retailers sales forecast for a product is 10000, in order to cope with the uncertainty of demand, heWill maintain a certain amount of inventory, so he will increase order
12、s on this basis, orders for quantitative change(1+X%) 10000; similarly, his previous wholesalers will increase their orders on the basis of their orders,Therefore, the quantity of order to the manufacturer becomes (1+X%+Y%) 10000Goods must be produced according to the quantity of the orderBullwhip e
