  摘要：We consider the stochastic, single-machine earliness/tardiness problem (SET), with the sequence of processing of the jobs and their due-dates as decisions and the objective of minimizing the sum of the expected earliness and tardiness costs over all the jobs. In a recent paper, Baker () shows the optimality of the Shortest-Variance-First (SVF) rule under the following two assumptions: (a) The processing duration of each job follows a normal distribution. (b) The earliness and tardiness cost pa...

  摘要：Indoor cell phone users often suffer poor connectivity. One promising solution to this issue, femtocell technology, has been rapidly developed and deployed over the past few years. One of the biggest challenges facing femtocell deployment is the lack of a clear business model. This study investigates the economic incentive for cellular operators (also called macrocell operators) to enable femtocell service by leasing spectrum resources to independent femtocell operators. We model the interacti...

  摘要：Inventory inaccuracy is common in many businesses. While retailers employ cash registers to enter incoming orders and outgoing sales, inaccuracy arises because they do not record invisible demand such as spoilage, damage, pilferage, or returns. This setting results in incomplete inventory and demand information. An important inventory control problem therefore is to maximize the total expected discounted profit under this setting. Allowing for dependence between demand and invisible demand, we...
• Gray Markets and Supply Chain Incentives AI翻译

  摘要：Gray markets are unauthorized channels that distribute a branded product without the manufacturer's permission. Since gray markets are not officially sanctioned by the manufacturer, their existence is assumed to hurt the manufacturer. Yet manufacturers sometimes tolerate or even encourage gray market activities. We investigate the incentives of a manufacturer and its authorized retailer to engage in (or tolerate) gray markets. The firms need to consider the trade-off between the positive effec...
• What Happens When Manufacturers Perform The Retailing Functions? AI翻译

  摘要：This study examines the effects of a relatively new channel structure on prices and sales in a large department store, which in recent years has switched the management of many of its product categories from a traditional retailer-managed system to a manufacturer-managed system. We find that the change caused overall retail prices to decrease. However, there was significant heterogeneity in the response across brands. In the cell phone category, brands with high market shares and inelastic dem...

  摘要：Product design has increasingly been recognized as an important source of competitive advantage. This study empirically estimates the impact of effective design on the market value of the firm. We use a firm's receipt of a product design award as a proxy for its design effectiveness. Based on data from 264 announcements of design awards given to commercialized products between 1998 and 2011, we find that award announcements are associated with statistically significant positive stock market re...

  摘要：We consider subscription-based rental organizations, such as Netflix, where the satisfaction of customers depends on the availability of requested products. Recommender systems, in a DVD-rental context, are typically used to help customers in finding the right movies for them. Accordingly, the focus in recommender system research is generally on making better predictions of users' ratings. In contrast, we focus on better utilizing these rating estimates in the operations of DVD-rental firms. W...
• Role of Bottom-Up Decision Processes in Improving the Quality of Health Care Delivery: A Contingency Perspective AI翻译

  摘要：Recent changes to health care reimbursements policy mandate hospitals to improve simultaneously on conformance and experiential quality. Conformance quality measures the level of caregivers' adherence to evidence-based standards of care while experiential quality measures the level of interaction between caregivers and patients. Hospitals operate in regulated environments characterized by heavy top-down control mechanisms that are conducible for improving conformance quality. However, mechanis...
• Reducing Hospital Readmissions by Integrating Empirical Prediction with Resource Optimization AI翻译

  摘要：Hospital readmissions present an increasingly important challenge for health-care organizations. Readmissions are expensive and often unnecessary, putting patients at risk and costing $15billion annually in the United States alone. Currently, 17% of Medicare patients are readmitted to a hospital within 30days of initial discharge with readmissions typically being more expensive than the original visit to the hospital. Recent legislation penalizes organizations with a high readmission rate. The...
• Measuring the Benefit of Offering Auxiliary Services: Do Bag-Checkers Differ in Their Sensitivities to Airline Itinerary Attributes? AI翻译

  摘要：When firms evaluate their service system design choices, there is typically more uncertainty surrounding the value that a particular auxiliary service provides than there is on the cost of providing that service. To help inform this decision, we propose an approach where we compare the relative value of the segment of passengers who use an auxiliary service to the relative value of the segment that does not use it. We demonstrate this approach for a typical auxiliary service common to the airl...
