  摘要：An extensive body of literature argues for the benefits of planned obsolescence, the strategy of designing products with low durability to induce repeat purchases from the consumers and allow the firm to sell a larger volume. Yet, several firms avoid planned obsolescence and instead offer products with high durability. In this paper, we offer a demand-side rationale for a high-durability product design strategy: the exclusivity seeking consumer behavior associated with conspicuous consumption....
• A Modeling Framework for Control of Preventive Services AI翻译

  摘要：We present a modeling framework for facilities that provide both screening (preventive) and diagnostic (repair) services. The facility operates in a random environment that represents the condition of the population that needs screening and diagnostic services, such as the disease prevalence level. We model the environment as a partially endogenous process: the population's health can be improved by providing screening services, which reduces future demand for diagnostic services. We use event...
• A Scenario-Based Approach for Operating Theater Scheduling Under Uncertainty AI翻译

  摘要：Elective operation scheduling significantly affects the financial health of a hospital and additional metrics important to stakeholders in an operating theater (OT) environment. In this research, we develop a novel scheduling formulation that explicitly considers the uncertainty in elective operation durations and also plans for potential randomly arriving urgent demands. Using a scenario-based modeling approach, the objective of this formulation is to maximize the expected profit associated w...
• Coil Batching to Improve Productivity and Energy Utilization in Steel Production AI翻译

  摘要：This paper investigates a practical batching decision problem that arises in the batch annealing operations in the cold rolling stage of steel production faced by most large iron and steel companies in the world. The problem is to select steel coils from a set of waiting coils to form batches to be annealed in available batch annealing furnaces and choose a median coil for each furnace. The objective is to maximize the total reward of the selected coils less the total coil-coil and coil-furnac...
• Making OM Research More Relevant: Why? and How? AI翻译
  作者：Tang, Christopher S.
  作者单位：University of California System; University of California Los Angeles
  摘要：Should OM research become more relevant? I provide my own perspective on this question and some practical ideas for our community to explore. This article is based on my Manufacturing and Service Operations Management (MSOM) Distinguished Fellow inaugural lecture given at the University of Toronto on June 29, 2015.
• Supplier Evasion of a Buyer's Audit: Implications for Motivating Supplier Social and Environmental Responsibility AI翻译
  作者：Plambeck, Erica L.; Taylor, Terry A.
  作者单位：Stanford University; University of California System; University of California Berkeley
  摘要：Prominent buyers' brands have been damaged because their suppliers caused major harm to workers or the environment, e.g., through a deadly factory fire or release of toxic chemicals. How can buyers motivate suppliers to exert greater care to prevent such harm? This paper characterizes a backfiring condition under which actions taken by prominent buyers (increasing auditing, publicizing negative audit reports, providing loans to suppliers) motivate a supplier to exert greater effort to pass the...
• Do High and Low Inventory Turnover Retailers Respond Differently to Demand Shocks? AI翻译

  摘要：This paper examines the differences in the behaviors of high (HIT) and low inventory turnover (LIT) retailers in responding to demand shocks. We identify quantity and price responsiveness as two mediating mechanisms that distinguish how high and low inventory turnover retailers manage demand shocks. Using quarterly firm -level data of 183 U.S. retailers between 1985 and 2012, we find that HIT retailers are able to respond quickly by changing their purchase quantities in response to demand shoc...
• Quality in Supply Chain Encroachment AI翻译
  作者：Ha, Albert; Long, Xiaoyang; Nasiry, Javad
  作者单位：Hong Kong University of Science & Technology
  摘要：We study a supply chain with manufacturer encroachment in which product quality is endogenous and customers have heterogeneous preferences for quality. It is known that, when quality is exogenous, encroachment could make the retailer better off. Yet, when quality is endogenous and the manufacturer has enough flexibility in adjusting quality, we find that encroachment always makes the retailer worse off in a large variety of scenarios. We also establish that, while a higher manufacturer's cost ...
