Based On The Emergency Inventory Manufacturers Backup Supply Strategy Research

Supply chain management has gradually become popular since the1990s.At present, the supply chain which started from the cooperation of a few enterprises has developed into a complex system which is cooperated by a large number of enterprises. With the intensifying market globalization, more and more enterprises joined the supply chain. The cooperation of enterprises with each other in the supply chain can win not only efficiencies but also costs for them. However, joining the supply chain cooperation, the enterprises have lost control of many links, which leads to increasing uncertainty and risk. The efficient management of the supply chain risk has become the new topic which draws great attention in the theoretical and practical circles. The supply chain disruption has become a hot topic in the scholars because of its multiple causes and large scope of influences. In the recent two decades, supply chain disruption caused by natural disasters and human being occurred frequently, which led to serious negative effects, some even affected the operation of the entire industry. The research, with the bases of such backgrounds, starts to study one of the risks of supply chain disruption, supply interruption. Based on the findings of our predecessors, the passage illustrates the effective strategies on the risk of supply interruption in detail, giving influence factors that need to be taken into consideration to each strategy; and the passage, which is on the premises of manufacturers’ choice of emergency inventory strategy and backup supply strategy, studies the mathematic model of minimizing risk of supply interruption, and offers answers to the model, acquired the optimal inventory level to the two risk strategies. Moreover, the conclusion of this passage provides manufacturers with a new reference standard of choosing the reserved supply strategy.
