Resilient supply network design based on contingency supply

Based on the traditional supply network and multiple sourcing model, and integrating strategic emergency stock and real options supply, a resilient supply model based on contingency supply is built. Finally, the model is validated through computation experiments. The results show that the model has more important practical significance compared with traditional supply network model. It can not only increase the resilience of supply network, but also balance cost, reliability and resilience of supply network.
