• Order Fulfillment Under Pick Failure in Omnichannel Ship-From-Store Programs AI翻译
  作者：Das, Sagnik; Ravi, R.; Sridhar, Srinath
  作者单位：Carnegie Mellon University
  摘要：Problem definition: We consider the setting where a retailer with many physical stores and an online presence seeks to fulfill online orders using an omnichannel fulfillment program, such as buy-online ship-from-store. These fulfillment strategies try to minimize cost while fulfilling orders within acceptable service times. We focus on single-item orders. Typically, all online orders for the item are sent to a favorable set of locations to be filled. Failed trials are sent back for further sta...
• Manage Inventories with Learning on Demands and Buy-up Substitution Probability AI翻译

  摘要：Problem Definition: This paper considers a setting in which an airline company sells seats periodically, and each period consists of two selling phases, an early-bird discount phase and a regular-price phase. In each period, when the early-bird discount seat is stocked out, an early-bird customer who comes for the discounted seat either purchases the regular-price seat as a substitute (called buy-up substitution) or simply leaves. Methodology/ Results: The optimal inventory level of the discou...
• Optimal Enrollment in Late-Stage New Drug Development with Learning of Drug's Efficacy for Group-Sequential Clinical Trials AI翻译

  摘要：Problem definition: The cost for developing a new drug ranged from $1 billion to more than $2 billion between 2010 and 2019. In addition to high development costs, the efficacy of the candidate drug, patient enrollment, the market exclusivity period (MEP), and the planning horizon are uncertain. Moreover, slow enrollment leads to increased costs, canceled clinical trials, and lost potential revenue. Many firms, hoping to detect efficacy versus futility of the candidate drug early to save devel...
• Increasing Biomanufacturing Yield with Bleed-Feed: Optimal Policies and Insights AI翻译

  摘要：Problem definition: Bleed-feed is a novel technology that allows biomanufacturers to skip intermediary bioreactor setups. However, the specific time at which bleed-feed is performed is critical for success. The process is stringently regulated, and its implementation involves unique tradeoffs in operational decision making. Our analysis formalizes the operational challenges related to bleed-feed decisions, and our results inform biomanufacturers and policymakers on the potential impact of this...
• Appointment Scheduling Under a Service-Level Constraint AI翻译

  摘要：Problem definition: This paper studies an appointment system where a finite number of customers are scheduled to arrive in such a way that (1) the expected waiting time of each individual customer cannot exceed a given threshold; and (2) the appointment times are set as early as possible (without breaking the waiting time constraint). Methodology/results: First, we show that, under the service-level constraint, a prospective schedule can be obtained from a sequential scheduling approach. In pa...
• Distance-Based Service Priority: An Innovative Mechanism to Increase System Throughput and Social Welfare AI翻译

  摘要：Problem definition: The main goal of many nonprofit or nongovernmental organizations is to increase the number of customers who receive service (i.e., service coverage) and social welfare. However, the limited number of employees, volunteers, and service locations results in long service wait. In addition, getting customers living in remote areas to receive services by traveling long distances is difficult. We propose an innovative distance-based service priority policy that would reduce the s...
• Follow the Crowd with Uncertain Service Capacity AI翻译

  摘要：Problem definition: Customer joining behavior is of major concern for service systems where the service capacity is uncertain. Academic/practical relevance: It remains unclear whether customer inference of uncertain service capacity can lead to follow the crowd (FTC) behavior. Management can release capacity information, but how it affects system performance needs to be understood. Methodology: We use a single-server queue to analyze the joining behavior of customers who infer the actual servi...
• Beating the Algorithm: Consumer Manipulation, Personalized Pricing, and Big Data Management AI翻译

  作者单位：University of Hong Kong; Indiana University System; Indiana University Bloomington; IU Kelley School of Business
  摘要：Problem definition: Firms heavily invest in big data technologies to collect consumer data and infer consumer preferences for price discrimination. However, consumers can use technological devices to manipulate their data and fool firms to obtain better deals. We examine how a firm invests in collecting consumer data and makes pricing decisions and whether it should disclose its scope of data collection to consumers who can manipulate their data. Methodology/results: We develop a game-theoreti...
• Sequential Innovation in Mobile App Development AI翻译

  摘要：Problem definition: In today's highly dynamic and competitive app markets, a significant portion of development takes place after the initial product launch via the addition of new features and the enhancement of existing products. In managing the sequential innovation process in mobile app development, two key operational questions arise. (i) What features and attributes should be added to existing products in successive versions? (ii) How should these features and attributes be implemented f...
• Go Wide or Go Deep? Assortment Strategy and Order Fulfillment in Online Retail AI翻译

  摘要：Problem definition: Expansions in product assortment by online retailers often engender operational challenges. In undertaking such expansions, retailers exercise a strategic choice between expanding assortment width or depth. Our understanding of how this choice affects the order fulfillment process is limited. Thus, we examine the impact of these dimensions of assortment strategy on order delivery timeliness. Academic/practical relevance: Order delivery timeliness is a critical measure of op...
