• Consistent Routing and Scheduling with Simultaneous Pickups and Deliveries AI翻译

  摘要：We study the planning and scheduling of order shipments among laboratories of an instrument-calibration company. To address a generic version of the company's combined routing and scheduling problem, we introduce a model variant with simultaneous pickups and deliveries in which consistency of site visits is also desired. We provide alternative formulations of the problem and propose branch-and-check and branch-and-price implementations, with an analysis of the instance characteristics for whic...
• Structural Results for Average-Cost Inventory Models with Markov-Modulated Demand and Partial Information AI翻译

  摘要：We consider a discrete-time infinite-horizon inventory system with non-stationary demand, full backlogging, and deterministic replenishment lead time. Demand arrives according to a probability distribution conditional on the state of the world that undergoes Markovian transitions over time. But the actual state of the world can only be imperfectly estimated based on past demand data. We model the inventory replenishment problem for this system as a Markov decision process (MDP) with an uncount...

  摘要：We study a setting where the nature of the collaboration necessitates two partner firms working together, which is often the case in supply chain and information technology (IT) environments. We consider that both firms get ongoing value from the project and the effort levels of both parties are dynamic. In this setting, one of the partners (say, the first partner) decides the terms of the payment it extends to the second partner in order to maximize the value it gets from the collaboration. W...

  摘要：We study a coin supply chain problem in the context of improving efficiency. While most consumer products are distributed in one direction, coins are recirculated and reused through the economy. The Federal Reserve System (FRS), the central banking system of the United States, plays a crucial role in managing the U.S. coin supply chain (CSC). It spends a significant fraction of its annual budget on operating the U.S. CSC in order to provide banking services to depository institutions (DIs) and...
• Blockchain for Supply Chain Traceability: Business Requirements and Critical Success Factors AI翻译

  摘要：We seek to guide operations management (OM) research on the implementation of supply chain traceability systems by identifying business requirements and the factors critical to successful implementation. We first motivate the need for implementing traceability systems in two very different industries-cobalt mining and pharmaceuticals-and present business requirements and critical success factors for implementation. Next, we describe how we carried out thematic analysis of practitioner and scho...
• Why Have Voluntary Time-of-Use Tariffs Fallen Short in the Residential Sector? AI翻译

  摘要：We investigate the causes behind the underwhelming adoption of voluntary Time-of-Use (TOU) tariffs in the residential electricity market. TOU tariffs are deployed by utilities to better match electricity generation capacity with market demand by giving consumers price incentives to reduce their consumption when electricity demand is at its peak. However, consumers in residential electricity markets are heterogeneous in their consumption preferences. Hence, utilities face a trade-off when deplo...
• Consumer Profiling with Data Requirements: Structure and Policy Implications AI翻译
  作者：Valletti, Tommaso; Wu, Jiahua

  摘要：We consider a model where a monopolist can profile consumers in order to price discriminate among them, and consumers can take costly actions to protect their identities and make the profiling technology less effective. A novel aspect of the model consists in the profiling technology: the signal that the monopolist gets about a consumer's willingness-to-pay can be made more accurate either by having more consumers revealing their identities, or by spending larger amounts of money (e.g., on thi...
• Volunteer Management in Charity Storehouses: Experience, Congestion and Operational Performance AI翻译

  摘要：We study volunteer management at a charity storehouse operated by a large faith-based organization. The storehouse runs entirely on volunteer efforts. We investigate the role of volunteer experience and storehouse congestion in the preparation of orders using a multi-method approach. First, we conduct a field study to explore these relationships and collect data at the level of volunteers' teams. These teams can pair volunteers with either different levels of experience (mixed pairing) or equa...
• Behavioral Ordering, Competition and Profits: An Experimental Investigation AI翻译

  摘要：We investigate the impact of behavioral ordering on profits under competition. Specifically, we use controlled laboratory experiments to evaluate the differences in profits between a behavioral competitor (where a human places orders), and a management science-driven competitor (where orders are placed according to one of several plausible policies based on existing literature and managerial practice). Unlike the full-information game-theoretic models that assume rational decision-makers, thes...
