We consider a supply chain setting where multiple uncapacitated facilities serve a set of customers with a single product. The majority of literature on such problems requires assigning all of any given customer’s demand to a single facility. While this single-sourcing strategy is optimal...

This paper analyzes the impacts of carbon regulatory mechanisms on replenishment decisions in a biofuel supply chain. We employ mathematical models for operations which integrate replenishment and supplier/transportation mode selection decisions. These models explicitly account for carbon...

The phenomenon in which demand variability increases as one moves upstream in the supply chain has been often observed in practice. This so-called “bullwhip effect” often increases upstream operations costs, including inventory holding and transportation costs. Price variations are...

Although splitting shipments across multiple delivery modes typically increases total shipping costs as a result of diseconomies of scale, it may offer certain benefits that can more than offset these costs. These benefits include a reduction in the probability of stockout and in the average...

We consider the allocation of a limited budget to a set of activities or investments in order to maximize return from investment. In a number of practical contexts (e.g., advertising), the return from investment in an activity is effectively modeled using an S-curve, where increasing returns to...

We consider a scheduling problem where the firm must compete with other firms to win future jobs. Uncertainty arises as a result of incomplete information about whether the firm will win future jobs at the time the firm must create a predictive (planned) schedule. In the predictive schedule, the...
