Construction Of A VMI Model In Two-level Supply Chain And Research On The Price Protocol Mechanism

Along with the rapid development of manufacturing enterprise in China, the stock management of various components becomes very important. In many manufacturing enterprises the inventory cost,especially the inventory cost of raw materials occupies lots of current capital. So it's very important to decrease the inventory of raw materials and reduce the inventory cost. the manufacturing enterprises can make use of material classification method synthetically, adopt differentiated management according to different types of materials,and make full use of VMI, the manufacturing enterprises can steadily ally with the vendors.This paper studys a two-level supply chain including multi-supplier and a manufacturing enterprise, multi-supplier supply components to the manufacturing enterprises. This paper makes innovation based on the ABC classification, forms a multifactor classified matrix model, then corresponding inventory strategy is selected according to the different features of the materials, this leads to a low cost, and resources can be effectively used. The key materials is managed with VMI, this paper researchs the optimal ordering quantity of all materials. This paper establishes an overall supply chain model which is to get the target of the maximum profit under BOM constraint, and also counts the most optimized ordering quantity of the suppliers of all components. Through the model, the manufacturing enterprise and its suppliers can make decision together, they decide replishment according to the proportion of the components of the BOM, manufacturing enterprise also can flexibly manage the inventory of the components. The result of this paper proves that the supply chain can reach the target of integrated inventory management and the efficiency of the inventory management can be improved.The VMI is used to carry out the tactic alliance, so this paper analyses the contract between the venders and the manufacturing enterprise. The paper studied from respect of supplier's profit as well as manufacturing enterprise's component cost. Both buyers and suppliers in supply chain are willing to sacrifice part self-profit to realize co-operation and double win. The paper constructs a revenues-sharing model between the supplier and the manufacturing enterprise. On specifical condition, the VMI can bring benefit to both the supplier and the manufacturing enterprise.
