  摘要：Provision of safe, timely care to hospital patients requires services from multiple support departments, such as environmental services and pharmacy. However, few studies have examined the impact of the service quality of internal support departments on clinical performance. The lack of studies linking internal service quality (ISQ) to clinical performance creates a gap in healthcare operations management theory and-from a practice standpoint-might contribute to underinvestment in the quality ...

  摘要：This paper reviews the state of the art in Productions and Operations Management (POM) academic research regarding outsourcing in supply chain contexts. We first acknowledge the Theory of the Firm (ToF), the venerable and vast body of thought regarding where the firm draws the boundary between what it performs in-house and what it outsources. Despite the clear linkage between outsourcing and POM, the ToF literature is most closely associated with the fields of strategy and economics. This disc...

  摘要：In this study, we propose a stylized Cournot competition model under asymmetric market information and study the formation of producers' informational coalitions. We offer guidance towards how the information service operations can improve the producers' welfare. Our results shed interesting light on farmer producer organizations (FPOs) in their efforts to link farmers in developing economies by integrating market information. To be specific, by focusing on Nash equilibria wherein producers ma...

  摘要：We study outpatient appointment block scheduling policies for single providers under conditions of patient heterogeneity in service times and patient no-shows. The objective is to find daily appointment schedules that minimize a weighted sum of patients' waiting time, the physician's idle time, and the physician's overtime. We contribute by suggesting new effective sequential block scheduling procedures motivated by actual outpatient clinic practices across the globe and grounded in the succes...

  摘要：In this issue, Cui etal. () show how the quantity and quality of user-generated Facebook data can be used to enhance product forecasts. The intent of this note is to show how another type of user-generated contentcustomer search data, specifically one obtained from Google Trendscan be used to reduce out-of-sample forecast errors. Based on our work with an online retailer, we bolster Cui etal. () result by showing that adding customer search data to time series models improves out-of-sample for...
• How Research in Production and Operations Management May Evolve in the Era of Big Data AI翻译

  作者单位：Purdue University System; Purdue University
  摘要：We are living in an era in which data is generated in huge volume with high velocity and variety. Big Data and technology are reshaping our life and business. Our research inevitably needs to catch up with these changes. In this short essay, we focus on two aspects of supply chain management, namely, demand management and manufacturing. We feel that, while rapidly growing research on these two areas is contributed by scholars in computer science and engineering, the developments made by produc...
• Integrated Commodity Inventory Management and Financial Hedging: A Dynamic Mean-Variance Analysis AI翻译

  摘要：We consider a firm purchasing a storable raw material commodity from a spot market with volatile commodity prices and the access to an associated financial derivatives market. The purchased commodity is processed into an end product with uncertain demand and lost sales. The firm aims to integrate the inventory replenishment and financial hedging decisions to maximize the mean-variance of terminal wealth over a finite horizon. Recognizing time-inconsistency of mean-variance criteria, we employ ...
• Should an Online Retailer Penalize Its Independent Sellers for Stockout? AI翻译
  作者：Xiao, Wenqiang; Xu, Yi
  作者单位：New York University; University System of Maryland; University of Maryland College Park
  摘要：We consider an online retailer selling a seasonal product provided by an independent third-party seller who has superior information about the demand potential of the product. The online retailer receives customer orders and then sends the orders to the seller for fulfillment, using pre-installed capacity. The supplier privately installs capacity prior to the selling season. The online retailer faces the challenge to accomplish two goals: to incentivize the seller to install the right level of...
• Supplier Quality Management: Investment, Inspection, and Incentives AI翻译

  作者单位：University of Hong Kong; University of Connecticut
  摘要：Buyers can manage product quality sourced from suppliers in three ways: they can improve the quality incoming from suppliers directly by investing in suppliers to improve a process/product, they can improve the incoming quality indirectly by incentivizing supplier quality-improvement efforts, and/or they can control the quality outgoing to subsequent processes by inspecting incoming units. In this study, we study a buyer's use of these three instrumentsinvestment, incentives, and inspectionto ...

  摘要：Having accurate, unbiased prognosis information can help patients and providers make better decisions about what course of treatment to take. Using a comprehensive dataset of all colorectal cancer patients in California, we generate predictive models that estimate short-term and medium-term survival probabilities for patients based on their clinical and demographic information. Our study addresses some of the contradictions in the literature about survival rates and significantly improves pred...
