摘要：This study considers a dyadic supply chain in which a large and creditworthy buyer procures a product from a capital-constrained supplier subject to disruption risk. In facilitating the production, the buyer may offer direct financing to the supplier by way of advance payment (AP). Concurrently, the buyer may also set a tailored discount rate (TR) that applies to the AP and an extended payment timeline (PE) for the balance due. We analyze the value and interplay of these elements by comparing ...

摘要：Two field case studies uncover information discounting in supply chains, which manifests in the form of schedule padding and order inflation. Buyers often exaggerate the urgency and quantity of their needs (crying wolf). However, both buyers and suppliers eliminate old, inflated orders from their behavioral ordering/supply system implicitly (knowing wink) even though they exist in the hyper-rational ordering system represented by the ERP system. This behavior results in (and from) low credibil...

摘要：Textile waste is one of the most pollutant items globally, being strongly affected by fast fashion (FF) products. Public pressure has made many FF firms voluntarily collect a small fraction of their preowned items and export them to developing countries for reuse. However, some developing countries are launching import bans on second-hand clothes. In addition, FF firms may soon be forced by extended producer responsibility legislation to collect more preowned items for reuse and recycling. To ...

摘要：We study a dynamic job assignment problem in queueing systems with one class of Poisson arrivals and K groups of heterogeneous servers. A scheduling policy prescribes the job assignment among servers in each group at every state n (number of jobs in the system). Our goal is to obtain the optimal policy to minimize the long-run average cost, which involves the increasingly convex holding cost for jobs and the operating cost for working servers. This problem has wide application scenarios in ope...

摘要：In this study, we develop a game-theoretic model to study the encroachment and information sharing decisions in a supply chain with a manufacturer selling through an online retail platform. In the base model, the manufacturer decides whether to encroach or not by selling through an agency channel, in addition to an existing reselling channel, at the same platform, who decides whether or not to share information with the manufacturer. We fully characterize the equilibrium decisions and show how...

摘要：To retain old customers and promote sales, firms offer trade-in programs in which consumers bring in an old product and receive a trade-in rebate when buying a new one. However, after buying the new product, the consumer who has traded in (the trade-in consumer) may return the new product and claim a refund for it if she/he is not satisfied with it. In this situation, under a full-trade-in-return (FTR) policy, trade-in consumers receive a generous refund that includes a trade-in-rebate for the...

摘要：Market share contracts, a form of loyalty discounts, where the discount is contingent on the buyer meeting or exceeding a target share of total procurement, are used in many business to business (B2B) settings. We study the impact of such contracts on demand allocation, prices, and welfare in a setting where a single central B2B buyer procures multiple units of a product on behalf of a set of users with heterogeneous preferences. We find that linear pricing creates a demand distortion, which g...

摘要：We consider the anesthesiologist staff planning problem for operating services departments in large multi-specialty hospitals without limit on anesthesiologist supply, where the planner makes monthly and daily decisions to minimize total costs. Each month the staff planner decides the number of anesthesiologists on regular duty and an on-call consideration list for each day of the following month. In addition, each day, the staff planner decides how many on-call anesthesiologists to call for t...

摘要：When a patient's illness perception is inconsistent with a doctor's diagnosis, she may seek opinions from multiple doctors without referrals, a behavior called doctor shopping. In this study, we model and derive patients' optimal doctor shopping decisions. After each visit, patients update their beliefs about their health status following the Bayes' rule. We show that the patients' doctor shopping decisions are critically affected by the diagnosis accuracy, the relative value of identifying a ...

摘要：This study centers on the roles of marketing and operations capabilities in preventing future recalls. However, prior literature identifies operations capability as critical for recall prevention, the current research highlights the equivalent importance of marketing capability. Furthermore, rather than limiting marketing's role to damage control efforts after a recall, this study identifies its potential for preventing future recall incidents. With research conducted in the consumer packaged ...
