摘要:Many publishers of online display advertising sell their ad resources through event-based auctions in the spot market. Such a way of selling lacks a holistic view of the publisher's ad resource and thus suffers from a well-recognized drawback: the publisher's revenue is often not maximized, particularly due to users' dynamic ad clicking behavior and advertisers' budget constraints. In this study, we propose a planning approach for ad publishers to better allocate their ad resources. Specifical...

摘要:Contests have long existed to source ideas and solutions. The emergence of crowdsourcing contest platforms greatly reduces the costs and broadens the reach of running contests by facilitating access to a large pool of labor, making contests a cost-efficient approach to procure ideas/solutions even for employers of limited resources. As a result, the use of contests surges and there is a flux of small-to-medium size contests to these platforms. This study focuses on these new waves of small-to-...

摘要:Data-driven sequential decision has found a wide range of applications in modern operations management, such as dynamic pricing, inventory control, and assortment optimization. Most existing research on data-driven sequential decision focuses on designing an online policy to maximize revenue. However, the research on uncertainty quantification on the underlying true model function (e.g., demand function), a critical problem for practitioners, has not been well explored. In this study, using th...

摘要:This study examines innovation tournaments in which an organizer seeks solutions to an innovation-related problem from a number of agents. Agents exert effort to improve their solutions but face uncertainty about their solution performance. The organizer is interested in obtaining multiple solutions-agents whose solutions contribute to the organizer's utility are called contributors. Motivated by mixed policies observed in practice, where some tournaments are open and others restrict entry, we...

摘要:Discrete convexity, in particular,L-convexity andM-convexity, provides a critical opening to attack several classical problems in inventory theory, as well as many other operations problems that arise from more recent practices, for instance, appointment scheduling and bike sharing. As a powerful framework, discrete convex analysis is becoming increasingly popular in the literature. This review will survey the landscape of the approach. We start by introducing several key concepts, namely,L-co...

摘要:Operations management has the tradition of coming from and going back to real-life applications. It deals with the management of the process of matching supply with demand. The emerging business process in a sharing economy or an innovative marketplace calls for active management at the operational level. We take a neoclassical perspective by drawing inspiration from the classic models in operations management and economics. We aim at building connections and identifying differences between th...

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: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: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...
