We consider a two-period sourcing and production problem. First, a firm (OEM) sources from multiple suppliers who have limited capacity and correlated disruption risk. After the supply is realized, the firm also has access to the spot market for the... Read More about Optimization Under Supplier Portfolio Risk Considering Breach of Contract and Market Risks..

We review empirical evidence from practice and general theoretical conditions, under which simple rules of thumb can help to make operations flexible and robust. An operation is flexible when it responds adaptively to adverse events such as natural d... Read More about Less can be more: How to make operations more flexible and robust with fewer resources.
