A Research On Reasonable Inventory Of Supply Chain In An Elevator Manufacturer

Inventory management is one of the most important parts of production management.Nowadays,enterprises interminably pursue the objective that the stocking must not only satisfies the need of production,but also minimizes the cost. Now the world is full of the fierce competition,the competition between enterprises become the competition between supply chain and supply chain. The stock management is an important contents within the supply chain management,a good stock management mode can lower the total cost of the supply chain,exaltation supply chain operation effieiency,increment profits.Given the development of foreign,the Vender Managed Inventory(VMI) is a newer problem in the domestic.This text with inventory management of a famous elevator manufacturer for background,based on the comparison between traditional inventory management module and VMI module,the point analyzed the function of the VMI in remove the bullwhip effect,and compare the VMI mode implement in front and back of the variety of the cost and profits. For a kind of inventory mode ,a supply chain model of vender managed inventory is established, on the basic of definite demand, no ready source of initial stock, no short supply and production time (T). The further analysis of the model reveals that VMI can reduce the total inventory-related costs and increase the total profit of the whole supply chain .Finally, a numerical example illustrates the results.The VMI is the supply chain stock of the forerunner that practiced to prove management mode,it can decline the low inventory and reduce the cost availably,improving to be out of stock,raise the service level and shorten to expect in advance,exaltation stock rate of turnover,raise the accuracy that need estimate.The research about this project not only can effectively improve supply chain level for our company, but also can promote the operation efficiencies for the other type supply chain.
