  摘要：This paper focuses on the proactive planning of a partial switch of a prescription (Rx) drug brand to over-the-counter (OTC) status within the former's patent-protected life. The planning issues are whether and when to make this switch from the single-status Rx drug phase to the dual-status Rx+OTC phase with or without the grant of a 3-year market exclusivity period for the OTC drug by the US Food and Drug Administration. We formulate an optimal control problem that leads to a two-phase optimi...
• An Analysis of Dual-Kanban Just-In-Time Systems in a Non-Repetitive Environment AI翻译

  摘要：Recent advances in approaches and production technologies for the production of goods and services have made just-in-time (JIT) a strong alternative for use in intermittent and small batch production systems, especially when time-based competition is the norm and a low inventory is a must. However, the conventional JIT system is designed for mass production with a stable master production schedule. This paper suggests supplementing the information provided by production kanbans with informatio...

  摘要：A few weeks before the start of a major season, movie distributors arrange a private screening of the movies to be released during that season for exhibitors and, subsequently, solicit bids for these movies (from exhibitors). Since the number of such solicitations far exceeds the number of movies that can be feasibly screened at a multiplex (i.e., a theater with multiple screens), the problem of interest for an exhibitor is that of choosing a subset of movies for which to submit bids to the di...
• Optimal Acquisition Quantities in Remanufacturing with Condition Uncertainty AI翻译

  摘要：The condition of the used products acquired by remanufacturing firms often varies widely. A firm can manage this variation by acquiring a quantity of used items that exceeds demand, enabling it to remanufacture a subset of the acquired items in the best condition. As more excess items are acquired, the firm can increase its selectivity and lower its remanufacturing costs. In this paper, we examine the tradeoff of acquisition and scrapping costs vs. remanufacturing costs when used product condi...
• Anatomy of a Newsvendor Decision: Observations from a Verbal Protocol Analysis AI翻译

  摘要：An exploratory analysis of verbal protocols from a think-aloud newsvendor experiment provided deeper insights into the decision-making process, enabling us to formulate a number of questions that are worth answering in future research. In a think-aloud experiment, subjects verbalize their cognitions while performing a task; responses are then recorded, transcribed, and analyzed. A majority of the subjects struggled with the abstractness of the business setting and were keen to know information...
• Tradeoffs in Manufacturing? A Meta-Analysis and Critique of the Literature AI翻译
  作者：Rosenzweig, Eve D.; Easton, George S.
  作者单位：Emory University
  摘要：An ongoing, important question in the operations strategy literature pertains to tradeoffs: Can manufacturers focus on multiple priorities simultaneously or achieve strength on multiple capabilities without sacrificing performance of another? In this paper, we accumulate, integrate, and examine the wide spectrum of conclusions reached in the literature concerning tradeoffs using modified meta-analysis methods. Based on two decades of empirical research in operations strategy, we find that the ...
• Operations in Financial Services-An Overview AI翻译
  作者：Hatzakis, Emmanuel D. (Manos); Nair, Suresh K.; Pinedo, Michael
  作者单位：University of Connecticut; New York University
  摘要：We provide an overview of the state of the art in research on operations in financial services. We start by highlighting a number of specific operational features that differentiate financial services from other service industries, and discuss how these features affect the modeling of financial services. We then consider in more detail the various different research areas in financial services, namely systems design, performance analysis and productivity, forecasting, inventory and cash manage...
• A Depository Institution's Optimal Currency Supply Network Under the Fed's New Guidelines: Operating Policies, Logistics, and Impact AI翻译

  摘要：The overuse of its currency processing operations by depository institutions (DIs) has motivated the Federal Reserve (Fed) to propose new currency recirculation guidelines. The Fed believes that DIs should play a more active role in recirculating fit (i.e., usable) currency so that the societal cost of providing currency to the public is minimized. The Fed characterizes the overuse by the extent of cross shipping, a practice in which the same DI deposits and withdraws currency of the same deno...

  摘要：Consider a manufacturer who mass customizes variants of a product in make-to-order fashion, and also produces standard variants as make-to-stock. A traditional manufacturing strategy would be to employ two separate manufacturing facilities: a flexible plant for mass-customized items and an efficient plant for standard items. We contrast this traditional focus strategy with an alternative that better utilizes capacity by combining production of mass-customized and standard items in one of two a...
• Shareholders' Wealth-Maximizing Operating Decisions and Risk Management Practices in a Mixed Contracts Economy AI翻译

  摘要：This paper establishes a critically important positive role for operations management practices and financial hedging. We show that operations management decisions and financial hedging are intertwined, and we advance a framework that can identify their combined effects on investors' wealth. We show that: (a) firms (publicly traded corporations) will optimally hold adequate riskless working capital (e.g., cash) to minimize the cost of obtaining non-financial inputs, and the magnitude of this c...
