Study On Supply Chain Disruption Management Based On Disruptions

As the supply chain system spans more and more countries and its structure becomes more and more complex, plenty of uncertainties appear. Contemporary supply chain management technology and thinking focuses on Lean Manufacture, Just in Time, Zero Inventory and so on, which brings great success, but also results in the supply chain more vulnerable to various disruptions. In fact, when a disruption occurs, many supply chains are forced to stop the normal businesses, and some even go bankrupt. With the rapid development of modern information technology, globalization of economy and global competition, the dynamics, complexity and uncertainty of the supply chain environment increases, which makes the supply chain often interrupted and the environmental quality deviate from steady state easily. Those increase the uncertainties of operational process of supply chain, and then make the supply chain is often vulnerable to various disruptions. Therefore, considering that it is difficult to avoid the occurrence of disruptions, it is necessary to develop the theory of supply chain disruption management, and discuss on how to make the supply chain rapid recovery to normal operation after the supply chain is influenced by a disruption.Firstly, from the perspective of supply chain, we analyze the basic problems of supply chain disruptions, namely the concept, characteristics and types. Secondly, considering that current research on supply chain disruption management only emphasizes changing real-time operation plan through adopting supply chain disruption management strategies after the supply chain is influenced by a disruption, which would increase the cost greatly, we bring forward supply chain disruption management strategies which make the supply chain not only possess the ability of sustaining its operation during a disruption and rapid recovery after a disruption, but also enhance the efficiency of supply chain by managing operational risks regardless of the occurrence of disruptions. Accordingly, supply chain disruption management strategies involving supply management strategies, demand management strategies, product management strategies and information management strategies are analyzed, and then a strategy system is constructed. Also, in order to offer decision-making support for adopting reasonable supply chain disruption management strategies, an optimization model is developed. Finally, after determining the supply chain disruption management strategy, in order to make the supply chain recover as soon as possible, and then minimize losses, MDP is used to discuss how to dynamically optimize the whole stochastic decision process effectively, and then a general mathematical model is developed.
