In this article we reflect on the supply chain issues and operations challenges that we experienced through the various stages of the COVID-19 pandemic. We identify a few phenomenon that were attributable in some way to the pandemic, and apply core principles of operations management, and a...

Operations managers do not typically have full information about the demand distribution. Recognizing this, data-driven approaches have been proposed in which the manager has no information beyond the evolving history of demand observations. In practice, managers often have some partial...

Disruptive events that halt production can have severe business consequences if not appropriately managed. Business interruption (BI) insurance offers firms a financial mechanism for managing their exposure to disruption risk. Firms can also avail of operational measures to manage the risk. In...

Lee [2004. The triple--a supply chain. Harvard Business Review 102-112] articulated that alignment, adaptability, and agility are the basic ingredients for managing supply chain risks. While it is clear that flexibility (agility) enhances supply chain resiliency, it remains unclear how much...

Dual sourcing and inventory are two prevalent and widely studied strategies firms use to manage yield risk. A pervasive but implicit assumption in the literature is that a firm knows its suppliers' yield distributions with certainty. This is a strong assumption in many circumstances. A firm is...

In this paper, we investigate price-only contracts in supply chain capacity procurement games. For a two-party supply chain, comprising a manufacturer and a supplier that both invest in capacity, we prove the existence of a class of coordinating price-only contracts that arbitrarily allocate the...

Surveys suggest that supply chain risk is a growing issue for executives and that supplier reliability is of particular concern. A common mitigation strategy is for the buying firm to expend effort improving the reliability of its supply base. We explore a model in which a firm can source from...

We connect the mix-flexibility and dual-sourcing literatures by studying unreliable supply chains that produce multiple products. We consider a firm that can invest in product-dedicated resources and totally flexible resources. Product demands are uncertain at the time of resource investment,...

Coproduction systems, in which multiple products are produced simultaneously in a single production run, are prevalent in many industries. Such systems typically produce a random quantity of vertically differentiated products. This product hierarchy enables the firm to fill demand for a...
