摘要:This paper discusses the origins of the supply chain contracting literature as well as its current state. It argues that its origins go back further than many scholars realize. It also makes the case that the field expanded rapidly, creating a bubble that has largely burst. However, there have been lasting implications that affect both how we teach supply chain management and the kind of research that is done under the heading of operations management.

摘要:For many entrepreneurs, time is a key constraint. They need to invest time to achieve growth, but also lose time because of recurring crises. We develop a simple stochastic dynamic program to model how an entrepreneur should prioritize between improving processes to reduce crises versus harvesting revenue or ensuring future growth. We show that it is initially optimal to prioritize process improvement: an entrepreneur should strive for high process quality early in the venture's growth process...

摘要:Online shoppers value lenient return policies as they are unable to assess whether products match their expectations. We study how consumers' discount-seeking purchase deferrals affect online retailers' return policy choices. Lenient returns may induce higher full-price sales by limiting consumer regret, while signaling clearance unavailability risk. Contrasting earlier research that concluded a monopolist must set the refund at the clearance price when strategic consumers were overlooked, we ...

摘要:We investigate information flow in two-tier supply chains, where retailers order from suppliers and sell in a market with uncertain demand. The retailers each have access to a demand signal and can exchange signals (horizontal information sharing). The suppliers can offer the retailers differential payments to gain access to their signals (vertical information acquisition). We demonstrate that retailer competition is a necessary condition to sustain information flow, whereas supplier competiti...

摘要:Co-production (simultaneous production of multiple outputs) occurs in some emission-intensive basic material and agricultural industries. This paper is motivated by ones in which a supplier sells its primary product to a buyer that incurs an emissions cost (voluntarily, or due to government-imposed climate policy) and sells co-products into markets without emissions costs. Emission-accounting standards provide three candidate rules for allocating the supplier's emissions among its products. Th...

摘要:Motivated by innovative rental business models, we study a rental system with random loss of inventory due to use. We utilize a discrete-time model in which the inventory level is chosen before the start of a finite rental season, and customers not immediately served are lost. Demand, rental durations, and rental unit lifetimes are stochastic; sample path coupling allows us to derive structural results that hold under limited distributional assumptions. Considering different recirculation rule...

摘要:We generalize the guaranteed-service (GS) model for safety-stock placement in supply chains to include capacity constraints. We first examine the guaranteed-service model for a capacitated single-stage system with bounded demand. We characterize the optimal inventory policy, which depends on the entire demand history. Due to this complexity, we develop a heuristic, namely a constant base-stock policy with censored ordering. This is an order-up-to policy but with its replenishment orders censor...

摘要:The development of predictive models in healthcare settings has been growing; one such area is the prediction of patient arrivals to the emergency department (ED). The general premise behind these works is that such models may be used to help manage an ED that consistently faces high congestion. In this work, we propose a class of proactive policies that utilize future information of potential patient arrivals to effectively manage admissions into an ED while reducing waiting times for patient...

摘要:Although influenza vaccine shortage is often attributed to low supply, it has been observed that even with abundant supply, a major shortage can still occur because of late delivery. In this paper, motivated by the influenza vaccine industry, we study a supply chain contracting problem in the presence of uncertainties surrounding design, delivery, and demand of the influenza vaccine. In this supply chain, a manufacturer has insufficient incentive to initiate at-risk early production prior to t...

摘要:We consider the problem of selecting the number of advanced life support (ALS) and basic life support (BLS) ambulances-the vehicle mix-to deploy in an emergency medical service (EMS) system, given a budget constraint. ALS ambulances can treat a wider range of emergencies, whereas BLS ambulances are less expensive to operate. To this end, we develop a framework under which the performance of a system operating under a given vehicle mix can be evaluated. Because the choice of vehicle mix affects...
