摘要：In practice, it is common, especially for online retailers, to bundle different products together during procurement to save transportation and handling costs. It is important to understand and theorize how to manage dynamic procurement by taking advantage of joint ordering in the presence of joint and individual setup costs. In this article, we characterize the structure of optimal policy for a periodic review multiproduct inventory system with multiple setup costs, including a joint setup co...

摘要：We study the assortment optimization problem under general linear constraints, where the customer choice behavior is captured by the cross-nested logit model. In this problem, there is a set of products organized into multiple subsets (or nests), where each product can belong to more than one nest. The aim is to find an assortment to offer to customers so that the expected revenue is maximized. We show that, under the cross-nested logit model, the unconstrained assortment problem is NP-hard ev...

摘要：We depart from the classic bundling literature on single-unit purchases and develop a multi-unit demand model in which customers decide both the variety and volume of their purchased products. We integrate product bundling with two commonly used usage-based pricing schemes in the service industry, pay-per-use and subscriptions, and examine pricing tactics that span both variety and usage. Our model captures customers' diminishing margins of consumption, and we demonstrate an intricate interpla...

摘要：Once autonomous vehicles (AVs) are deployed for ride-hailing platforms, human drivers will compete with AVs until AV costs decrease enough to eliminate human drivers entirely. We examine a ride-hailing platform's strategy to recruit human drivers while operating a private AV fleet. Using a game-theoretic model, we analyze how the platform sets the human-driver wage and the size of its AV fleet. We show that setting a higher wage can surprisingly lead to less human-driver participation. Moreove...

摘要：Antibiotic resistance is an ongoing public health crisis fueled by overuse and misuse of antibiotics. The goal of this article is to examine the impact of action-based incentive payments on reducing inappropriate antibiotic prescriptions in primary care, where 30%-50% of antibiotic prescriptions are inappropriate. Various financial incentive programs to reduce the rate of inappropriate antibiotic prescriptions have been implemented and studied empirically. However, there have not been analytic...

摘要：This paper investigates a risk-averse firm's investment strategy in real-time event-monitoring technologies coupled with dynamic disruption response decisions. The firm does not know how long the disruption will last, and the event-monitoring solutions provide the firm with a quicker update regarding the length of the disruption. When the firm receives an update, it has the flexibility to revise its initial response action. We model a two-stage stochastic program to study this problem where ri...

摘要：With the rise of the digital economy, many firms are enhancing product line flexibility (i.e., the ability to adjust product line length or depth) to better manage demand uncertainties brought about by disruptive technologies. Concurrently, the booming digital economy has widened the information gap in supply chains. Retailers/platforms can now gather more detailed data to predict demand, but such data remains unavailable to manufacturers. This article studies how a manufacturer's product line...

摘要：Competing firms may engage in group buying (GB) to benefit from a quantity discount from a common supplier. We study GB under different power structures (i.e., Nash and Stackelberg) and investigate how the power structures can be endogenized along with the resulting GB outcome. We employ a game-theoretic framework in which two firms under Cournot competition can group their purchases if it is beneficial compared to individual purchasing. We show that under exogenous power structures, when the ...
