Research On Design Of Resilient Supply Network Under Disruption Risk

With the rapid growth of technology and global economy, social division becomes more elaborate and supply network comprises more companies. Today’s Supply networks span the globe and involve many suppliers, suppliers’suppliers, contract manufactures, distributors, logistics providers, original equipment manufacturers(OEM), wholesalers, and retailers. This web of participating players creates more complexities, making it difficult to realize where vulnerabilities may lie. It also enhances the uncertainties of operation circumstance.Supply networks are often vulnerable to various failures. The failure which occurs at any node or link of supply network affects rapidly all companies in the web, and then, influences the normal operations of the whole network. Therefore, it has important value and significance to research on how to make supply network possess the ability of rapid recovery from failure to normal operations.This paper takes Supply Network Resilience under failure Risk Environment as the research objects. The paper finishes the work in the following four aspects:(1)We introduce the background of this paper, make a review of the literatures on supply chain risk and supply chain failure, introduce the method and recent research advance in this field, and brief the study’s purpose and significance.(2)We elaborate supply network resilience, supply network vulnerability and measure of increasing the supply network flexibility. It is emphasized that risk management in supply chain management is very important.(3)Designing inbound supply network with multi-sourcing method, network cost is optimization in the premise of considering the possibility of supplier failure and the possibility of the loss after failure. The model integrates advantages of cost minimization and maximum flexibility. After that, a numerical example demonstrates the effectiveness and feasibility of the model.(4) Supply model bases on multi-sourcing model and involves supply network reliability. Strategic emergency stock and options supply are introduced as two contingency supply modes in the model. We design resilient supply network model integrated with order policy and interference incidents. The model considering the balance of Supply network operating costs, the supply network reliability and network flexibility. Finally, a numerical example illustrates the effectiveness and feasibility of the proposed model.In addition, at the end of this paper, we summarize the main findings and conclusions, major contribution and limitations and requiring work for further research.
