The research history and development of the inventory models were reviewed and the latest research results were discussed. Finally, the future research directions of the inventory management in supply chain management were given. The inventory management was under way of integration, the IT and Internet will be considered and paid more and more attentions to inventory modeling, and inventory modeling under asymmetric information will bee more valuable and practicable.。 however it needs to be studied more intensively and extensively.V.CONCLUSIONIn this paper, three types of inventory models were discussed from the aspects of supply chain management:(1)Multisupplier and multiproduct inventory model。 more and more manufacturers in the supply chain form the strategic alliance. Inventory management is also in the direction of integration. Consequently, the single manufacturer or supplier has to establish integrated inventory model in view of the supply chain from upstream to downstream when they make decision of the inventory management, and multiechelon inventory modeling needs to be applied. B. Internet and Ebusiness based virtual inventory modeling With the development and application of the Internet and Ebusiness in supply chain, the purchase and order costs between buyers and sellers are decreasing, and the risks of suppliers are being reduced. This results in that multiple suppliers’ pattern is superior to single supplier pattern. The development of IT causes informationsharing between the buyers and the sellers. Buyer’s demand can be forecasted based on the information of the venders, however, suppliers should deal with a great deal of data. Therefore, Data Mining and Knowledge Discovery in Database have the wide application prospects in inventory management。 Huynh Trung Luong, and Ram Ganeshan introduced the multisupplier (N suppliers) in their inventory models, discussed the models of the multisupplier (N suppliers) in detail and gave the optimized policy for inventory control. Considering that the uncertainties, such as the failure of the equipments, the strike of workers, the adverse climatic conditions and so on, would affect the suppliers to supply the goods on time, in 1996, Parlar amp。 or else if xt Se , the emergency ord
