摘要：Outsourcing stretches supply chains longer with added contract manufacturers responsible for the manufacturing of parts and final products. Should a firm change its quality management approach as its supply chain becomes longer with outsourced manufacturing? This paper studies a brand owner's optimal choice between two commonly used quality management approaches: an inspection-based approach and an external failure-based approach, in two supply chains - a dyadic supply chain and a multi-level ...

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...

摘要：A common problem faced by many firms in their supply chains can be abstracted as follows. Periodically, or at the beginning of some selling season, the firm needs to distribute finished goods to a set of stocking locations, which, in turn, supply customer demands. Over the selling season, if and when there is a supply-demand mismatch somewhere, a re-distribution or transshipment will be needed. Hence, there are two decisions involved: the one-time stocking decision at the beginning of the seas...

摘要：Even though patients often arrive early and out of turn for scheduled appointments in outpatient clinics, no research has been undertaken to establish whether an available provider should see an early patient right away (preempt) or wait for the patient scheduled next. This problem, which we call the Wait-Preempt Dilemma, is particularly relevant for high-service-level clinics (such as psychotherapy, chiropractic, acupuncture), where preempting may cause the missing patient to wait for an exce...

摘要：Patent intermediaries have gained importance as non-practicing entities in the innovation domain, buying innovations from an external provider and then licensing them to practicing firms. In this study, we analyze the competition between two identical incumbent firms and a patent intermediary for the acquisition and licensing of a cost-reducing innovation developed by an external innovator. We show that the outcome of the IP acquisition and licensing game critically depends on the degree of th...

摘要：What is the link between customer-base concentration and inventory efficiencies in the manufacturing sector? Using hand-collected data from 10-K Filings, we find that manufacturers with more concentrated customer bases hold fewer inventories for less time and are less likely to end up with excess inventories, as indicated by the lower likelihood and magnitude of inventory write-downs and reversals. Using disaggregated inventory disclosures, we find that inventory efficiencies primarily flow th...

摘要：In recent years, there has been increasing pressure on the US federal government to reduce spending and improve the management of its technology projects. Mitigating the adverse impact of risks on the performance of these projects presents a significant challenge for its stakeholders. Our research examines this challenge in two steps. First, we identify and define a set of salient risks in federal technology projectsspecifically, complexity risk and contracting risk in the planning process, an...

摘要：We model the global vehicle supply chain of an International Humanitarian Organization (IHO) with a dynamic hub location model across monthly periods. We use actual vehicle data from the International Federation of the Red Cross to feed our model and provide insights into IHO secondary support demand. We find that secondary support demand for items such as vehicles is different from primary beneficiary demand for items such as water and food. When considering disaster response and development ...

摘要：Recent research on decision framing has shown that (i) there are multiple types of framing effects and (ii) the context of the decision can influence framing effects. This research examines decision framing effects in inventory control contexts by questioning the assumption of procedure invariance, that preference should not be impacted by how options are presented to a supply chain manager making an inventory control decision. Study 1 uses three single-shot decision experiments to establish t...

摘要：In a technology project, project integration represents the pooling together of complete, interdependent task modules to form a physical product or software delivering a desired functionality. This study develops and tests a conceptual framework that examines the interrelationships between the elements of work design, project integration challenges, and project performance. We identify two distinct elements of work design in technology projects: (i) the type of project organization based on wh...
