摘要:Manufacturers adopt a variety of channels for the sale of their products in the attempt to deliver the highest possible value to end consumers. For instance, a manufacturers' retail arm provides consumers with the instant gratification of product purchase and the benefit of in-store shopping assistance, whereas their online arm offers potential benefits by selling to market segments that value shopping convenience, product variety, availability, and customization. The main difference between t...

摘要:Operations management provides many exciting opportunities for improving the delivery of healthcare services. Much of the existing literature has focused on the efficient and cost effective delivery of good-quality care. Recently, there has been a growing demand for a more direct consideration of the wants, needs, and preferences of individual patients. This drive for patient-centric care coincides with and is fed by a dramatic explosion in the availability of data and analytics tools. The 12 ...

摘要:Digital assets are growing in scale, scope, and importance, amplifying the necessity to maintain their confidentiality. Yet, digital confidentiality has received vastly less research attention from operations and supply chain management (OSCM) scholars than cost, quality, flexibility, delivery, and innovation. We contend that this lack of attention has, at least partly, produced recommendations that ultimately could harm digital confidentiality performance. To guide future research, we synthes...

摘要:The literature has shown that supply chain performance is affected by the allocation of inventory risk. Traditionally, a pull supply chain generates a higher optimal order quantity and hence higher supply chain profit than a push supply chain when firms are risk neutral. Extended from the classic push and pull newsvendor models, this study investigates the impact of firms' risk-averse attitudes on supply chain performance. Based on firms' conditional value-at-risk (CVaR), our analysis indicate...

摘要:It is well established that human newsvendors tend to order insufficient inventory in high-marginsituations, possibly due to implicit risk aversion. In this study, we investigate the use of framing to change newsvendors' risk preference in order to induce them to make better ordering decisions. Through an exploratory experiment and five different treatments of the newsvendor problem, we found risk reversal only in the treatments with one question. In the other four treatments and the explorato...

摘要:While the value of using social media information has been established in multiple business contexts, the field of operations and supply chain management have not yet explored the possibilities it offers in improving firms' operational decisions. This study attempts to do that by empirically studying whether using publicly available social media information can improve the accuracy of daily sales forecasts.We collaborated with an online apparel retailer to assemble a dataset that combines (1) ...

摘要:In this day, in the age of big data, consumers leave an easily traceable digital footprint whenever they visit a website online. Firms are interested in capturing the digital footprints of their consumers to understand and predict consumer behavior. This study deals with how big data analytics has been used in the domains of information systems, operations management, and healthcare . We also discuss the future potential of big data applications in these domains (especially in the areas of clo...

摘要:One prevalent assumption in queueing theory is that the number of servers in a queueing model is deterministic. However, randomness in the number of available servers often arises in practice, e.g., in virtual call centers where agents are allowed to set their own schedules. In this paper, we study the problems of staffing and controlling queueing systems with an uncertain number of servers and impatient customers. Because randomness in the number of servers creates congestion in the system, t...

摘要:Empirical work on order fulfillment strategies suggests that building products to customer order is an important driver of organizational value. Similarly, the experimental literature indicates that customers derive value from customization. The modeling literature provides a more equivocal perspective, suggesting that a combination of build-to-forecast and build-to-order (BTO) fulfillment modalities may lead to the best system-wide outcomes. Using an industry studies approach, we build on the...

摘要:Patients admitted to a hospital's intensive care unit (ICU) often endure prolonged boarding within the ICU following receipt of care, unnecessarily occupying a critical care bed, and thereby delaying admission for other incoming patients due to bed shortage. Using patient-level data over two years at two major academic medical centers, we estimate the impact of ICU and ward occupancy levels on ICU length of stay (LOS), and test whether simultaneous surge occupancy in both areas impacts overall...
