Study On The Inventory Control Policy Of Supply Chain Management

With the development of supply chain and logistic, inventory control is important to reduce the supply chain cost and improvement the supply chain efficiency as the key tache under supply chain management.We researched the one -state, two-state, and multil-echelon inventory model under supply chain, and given the corresponding inventory control strategy taking into account supply chain practice in our enterprises. G.Padmanabhan, Prem Vart develop EOQ models for perisable items under stock dependent selling rate. In their models, they consider without backlogging, completely backlogging and partly backlogging. Kun-Jen Chung , Peter Chu, Shaw-Ping Lan gave the proof to the models of without backlogging and completely backlogging. The author relax this assumption and assume selling price changeable linearly with exterior demand rate ,and develop an EOQ model without backlogging for deteriorating items under stock dependent selling rate. The proof of the sufficient condition is done for the global optimal value . In addition, an example is given to explain the theory.Cetinkaya, Chung-Yee Lee.(2000) developed the Stock Replenishment and Shipment Scheduling for Vendor-Managed Inventory System in Management Science. However, there is some error about the carrying cost besides the complex parameter of their model. The author redefined the carrying cost and developed a new periodic review. In our model, The author took both the customer demand and the shipment scale economic into consideration. and decided whether giving a new order to replenish the stock before a shipment. We also optimized our model and given the global optimal value . Finally, an example was given contrasted with EOQ model.. We also introduced the basic content and procedure of Joint Inventory Managed , and analyzed the information how to work in this system and how to reduce the bullwhip effect.We analyzed the inventory cost components under multilevel supply chain ,and developed the and interior supply chain cost to optimize the supply chain cost. Furthermore , we introduced the basic thought, operation procedure of Collaborative Planning, Forecasting & Replenishment model .At last ,we given some advice how to reduce the cost in supply chains management.
