  摘要：We discuss the optimal raw material acquisition strategy for a third party remanufacturer (3PR). We specifically investigate whether a 3PR should acquire used products or cores in bulk with uncertain quality levels, or in sorted grades with known quality levels; and whether to acquire and remanufacture cores before the demand is realized (planned acquisition), or after the demand is realized (reactive acquisition), or on both occasions (sequential acquisition). When only sorted cores are acqui...
• Managing the Revenue of Sales Platforms: Insights into Service Fees AI翻译

  摘要：Online sales platforms have grown substantially in recent years. These platforms assist sellers to conduct sales, and in return, collect service fees from sellers. We study the fee policies by considering a fee-setting platform, on which a seller may conduct a sale with a reserve price to a group of potential buyers: the seller retains the object for sale if the final trading price is below the reserve price. The platform may charge two types of fees as in current practice: a reserve fee as a ...
• Experimental Results Indicating Lattice-Dependent Policies May Be Optimal for General Assemble-To-Order Systems AI翻译

  摘要：We consider an assemble-to-order (ATO) system with multiple products, multiple components which may be demanded in different quantities by different products, possible batch ordering of components, random lead times, and lost sales. We model the system as an infinite-horizon Markov decision process under the average cost criterion. A control policy specifies when a batch of components should be produced, and whether an arriving demand for each product should be satisfied. Previous work has sho...

  摘要：Facing the growing concern of environmental impact, green service (GS) has emerged as an important research topic in production and operations management. However, empirical research on GS is hindered by the lack of theoretically developed and empirically validated measurement scales covering various practices in service operations of a supply chain. GS indicates the strategic orientation of firms in developing a combination of practices and routines to reduce environmental impact in service o...
• Optimal Choice for Appointment Scheduling Window under Patient No-Show Behavior AI翻译
  作者：Liu, Nan

  摘要：Observing that patients with longer appointment delays tend to have higher no-show rates, many providers place a limit on how far into the future that an appointment can be scheduled. This article studies how the choice of appointment scheduling window affects a provider's operational efficiency. We use a single server queue to model the registered appointments in a provider's work schedule, and the capacity of the queue serves as a proxy of the size of the appointment window. The provider cho...
• Operational Productivity, Corporate Social Performance, Financial Performance, and Risk in Manufacturing Firms AI翻译

  摘要：We examine the relationship between Operational Productivity (OP), Corporate Social Performance (CSP), Financial Performance (FP), and risk. Our sample frame comprises 476 firms in nine US manufacturing industries during the period 1999-2009. We employ DEA-based measures for OP and CSP, two operationalizations for FP to reflect current profitability and market value, and two operationalizations for risk to reflect bankruptcy risk and stock price volatility. We confirm that OP is essential for ...
• An Entropy Measure of Flow Dominance for Predicting Operations Performance AI翻译

  摘要：The flow of jobs within a system is an important operating characteristic that influences system performance. While the majority of previous studies on manufacturing performance consider product flows only as an implicit parameter of the design, we introduce an explicit measure of flow dominance based on entropy and test its efficacy in predicting the performance of manufacturing systems. In computing entropy flow dominance (EFD), we aggregate information embedded in the routings of all produc...
• Problem Formulation and Solution Mechanisms: A Behavioral Study of Humanitarian Transportation Planning AI翻译

  摘要：When dealing with urgent, ill-defined problems, such as rapidly evolving emergency situations, operations managers have little time for problem formulation or solution. While the mechanisms by which humans formulate and solve problems have been described, mechanisms for rapid, concurrent formulating and solving are not well understood. This study investigates these mechanisms through a field study of transportation planning in a humanitarian response setting. The findings show that the problem...
• Addressing Supply-Demand Imbalance: Designing Efficient Remanufacturing Strategies AI翻译

  摘要：The management of remanufacturing inventory system is often challenged by mismatched supply (i.e., returned units, called cores) and demand. Typically, the demand for remanufactured units is high and exceeds the supply early in a product's lifetime, and drops below the supply late in the lifetime. This supply-demand imbalance motivates us to study a switching strategy to facilitate the decision-making process. This strategy deploys a push mode at the early stage of a product's lifetime, which ...
• Assembly Systems with Sequential Supplier Decisions and Uncertain Demand AI翻译

  摘要：We consider multitier push assembly systems with sequential supplier decisions and a wholesale price contract. We show that both an Original Equipment Manufacturer (OEM)-Contract Manufacturer (CM) assembly and a modular assembly with sequential supplier decisions are mathematically equivalent to the corresponding traditional assembly. We determine that, in most cases, the first mover supplier realizes a higher profit than the second mover supplier but we also identify the sufficient conditions...
