Over 97% of the power generation capacity to be installed from 2021 to 2050 in the U.S. is expected to be powered by wind, solar, and natural gas. Meanwhile, large-scale battery systems are planned to support the power systems. It is paramount that policy makers and electric utilities understand...

In this paper, we model a firm that can reduce its carbon footprint in the presence of a segment of eco-conscious consumers, who consider the product's carbon footprint when making purchasing decisions. The firm can reduce its controllable emissions, at increased fixed and variable costs, and it...

We study the competition between two remanufacturers in the acquisition of used products and the sales of remanufactured products. One firm has a market advantage; we consider two separate cases where either firm could have an acquisition advantage. The problem is formulated as a simultaneous...

We investigate when and how an original equipment manufacturer (OEM) should offer a trade-in rebate to recover used products, in order to achieve better price discrimination and weaken competition from third-party remanufacturers (3PRs). This paper is motivated by a major IT equipment OEM, which...

This paper studies a multiclass queueing system with endogenous abandonments where congestion affects customers' abandonment behavior and vice versa. Our model captures this interaction by developing two closely related models: an abandonment model and a queueing model. In the abandonment model,...

Problem Definition: Combined heat and power (CHP) plants generate electricity and useful heat at the same time, reaching high efficiencies. There are many benefits to utilities of having CHP plants in their portfolio, including increasing power reliability, reducing transmission losses, and...

This paper studies the callback option as an instrument to effectively mitigate congestion due to temporary surges in arrivals to a call center. The call arrival process can be an arbitrary point process, allowing uncertainty and temporary surges in the arrival rate, provided that the system is...

This paper studies a Geo/Geo/1 GI queue in which the abandonments are endogenous. One crucial feature of this model is that the abandonment behavior is affected by the system performance and vice versa. Our model captures this interaction by developing two closely related models: an abandonment...

We consider a variation of the economic order quantity (EOQ) model where cumulative holding cost is a nonlinear function of time. This problem has been studied by Weiss (1982), and we here show how it is an approximation of the optimal order quantity for perishable goods, such as milk, and...
