Much of the previous research on supply network resilience examined what capabilities firms should develop and how they develop the capabilities as resilience investment. However, what has received less attention is where to invest resilience in the network. Scholars have debated over what nodes...

Given an input graph Gin =(V,E_in), we consider the problem of designing a sparse subgraph G = (V, E) with E ⊆ E_in that supports a large matching after some nodes in V are randomly deleted. We study three families of sparse graph designs (namely, Clusters, Rings, and Erdős-Rényi graphs) and...
