We provide a review of the types of equilibria typically found in operations management inventory papers and a discussion on when the commonly used stationary infinite-horizon (open-loop) equilibrium may be sufficient for study. We focus particularly on order-up-to and basestock equilibria in...

We investigate the situation where a customer experiencing an inventory stockout at a retailer potentially leaves the firm's market. In classical inventory theory, a unit stockout penalty cost has been used as a surrogate to mimic the economic effect of such a departure; in this study, we...

Industry 4.0 connotes a new industrial revolution centered around cyber-physical systems. It posits that the real-time connection of physical and digital systems, along with new enabling technologies, will change the way work is done, and therefore, how work should be managed. It has the...

We study capacity decisions in a service environment with seasonal arrival rates and strategic customers. Due to seasonality, the firm uses a postponement strategy where compensation is given to the peak-time customers who cannot be served in the peak time and agree to delay service. We extend...

This paper analyzes the United States Medicare hospice reimbursement policy. The existing policy consists of a daily payment for each patient under care with a global cap of revenues accrued during the Medicare year, which increases with each newly admitted patient. We investigate the...

Hospital emergency departments (EDs) typically rely on central laboratories to analyze patient samples for the purposes of diagnosing and treating patients. Point-of-care testing (POCT) is a process redesign that shifts the analysis of samples from the central lab to the ED. Using a queueing...

Consumer reaction to (non)responsible sourcing (i.e., boycotting non-responsible firms and paying more for certified versions of products) determines firms’ sourcing strategies in a given market. Based on evidence from the marketing literature, in this paper we assume that the type of consumer...

There are many types of innovation used by companies along different dimensions. Here our focus is on innovation designed to improve the competitive capabilities of efficiency and responsiveness. We ask whether such innovation is uniformly good and find that it is not. We examine the mediating...

This study aims to explore the impact of changing the number of shipping lines on ports' charges and profits. A two-stage non-cooperative game-theoretic model is developed with two ports and multiple identical shipping lines. At the first stage, the ports decide their container handling charges....
