Unexpected events such as contingency and disruption have negative impacts on the survival and performance of supply chain networks. Nodes and links may be added and deleted, or part of networks can be disconnected. Providing resilient capability against failures is a critical issue for supply chain networks since a single failure may propagate along the chain and cause a series of severe losses on network performance and structure. Designinga robust supply chain network is an important research issue. In order to in- vestigate the relationship between robustness metrics and basic network parameters, a system-wide ap- proach was presented to quantify the robustness of supply chain networks. This approach considers both network structural and network functional parameters. A hypothetical supply chain network was employed to illustrate the proposed approach. The results show the proposed approach is effective.
