摘要：Inpatient flow management plays a critical role in care delivery, patient outcomes, and hospital operational and financial costs. Modeling and performance analysis of inpatient flow present unique features and challenges that differ from operations in other service industries. In this study, we review recent modeling and analytical advances in the setting of inpatient flow management, with a particular focus on service time models motivated from the observations of inpatient discharges. We fir...

摘要：Traditional production planning is primarily a quantity or capacity decision, which must be made at the beginning of a planning horizon before production starts. Adding to this decision a real-time control, a risk-hedging strategy carried out throughout the horizon can better mitigate the risk involved in demand volatility. We demonstrate how this can be done in terms of jointly optimizing the capacity and the hedging decisions, addressing both the mean-variance and the shortfall objectives. S...

摘要：We investigate a dynamic contracting problem in a supply chain with a manufacturer selling a seasonal product through a retailer over two periods. In period 1, which is before the selling season, neither firm knows the demand information. The manufacturer runs on the regular production mode with low production cost but long lead time. In period 2, which refers to the selling season, only the retailer can update the demand information, so information asymmetry exists in the supply chain. The ma...

摘要：We argue that in analyzing panel-data econometric models, researchers rely excessively on statistical criteria to determine model specification, treating it primarily as a matter of statistical inference. This inferential emphasis is most obvious in the common practice of using statistical tests (e.g., the Hausman test) to choose between fixed- and random-effects specifications, often ignoring the assumptions underpinning these tests. For instance, the Hausman test depends on the true within-p...

摘要：The Triple-A supply chain (Lee 2004) has become one of the most influential concepts for practitioners and researchers in supply chain management. It stipulates that supply chains should strive to improve along the dimensions of agility, adaptability, and alignment, as opposed to focusing exclusively on cost and efficiency improvements. While various strategies have since been adopted across different industries to foster the Triple-A, the digitalization movement poses both new challenges and ...

摘要：Regions with carbon emission regulations bear the risk of carbon leakage if local producers shift production capacity to an unregulated region. We investigate the problem for a producer subject to geographically asymmetric emission regulation with uncertain future emission price. The producer has twoex anteoptions to lower its compliance cost: investing in clean production technology in the regulated region and building production capacity in the unregulated region. The producer determines its...

摘要：Inspired by the opportunities provided by the Industry 4.0 technologies for smarter, risk-informed, safer, and resilient operation, control, and management of the lifeline critical networks, this study investigates mobility-as-a-service for resilience delivery during natural disasters. Focusing on effective service restoration in power distribution systems, we introduce mobile power sources (MPSs) as the restoration technology of the future, the mobility of which can be harnessed for spatiotem...

摘要：Service contracts are common practice in some industries while being eliminated in others. To investigate this phenomenon, we identify expectation-reality discrepancy (ERD) as a key determinant. A provider's ERD is defined as consumers' ex-ante expected valuation minus their ex-post realized valuation of the provider's service. Our analysis reveals that providers' contract strategies critically depend on their ERDs rather than the true service valuations. A provider with a higher ERD is more l...

摘要：To address the food assistance crisis during the Covid pandemic, the United States Department of Agriculture (USDA) launched a multi-billion dollar Farmers to Families Food Box program (Box program) by working with approved suppliers (or distributors) to purchase fresh produce, dairy, and meat directly from farmers and package them into boxes. Recognizing that food banks did not have spare capacity to support the Box program, how should these food boxes be distributed to people who are in need...

摘要：We partnered with a leading US academic medical center to empirically examine the impact of operational process changes designed to improve preoperative flow of patients through the perioperative environment. We focus on the implementation of centralized decision-making and the introduction of an information technology (IT)-enabled intraoperative prompt, on efficiency, as measured by preoperative patient processing time. We analyze over 33,000 individual surgical cases in a unique field experi...
