摘要：Ride-hailing platforms such as Uber and Lyft promise to reduce the negative externalities of driving and improve access to transportation. However, recent empirical evidence has been mixed about the impact of ride-hailing on US cities, often resulting in a net increase in traffic congestion and greenhouse gas (GHG) emissions, largely due to increased travel demand and competition with public transit. Pooled rides, in which multiple passengers share a single vehicle, are an effective solution t...

摘要：COVID-19 is a highly contagious disease that has spread to most countries at unprecedented transmission speed. Medical resources and treatments provided by the healthcare system help reduce the mortality rate and spread of COVID-19 by isolating infectious individuals. We introduce a modified SEIR model that considers individuals access to limited medical resources to characterize the central role of medical resources during the pandemic. We discuss how the three hospital admission policies (hi...

摘要：We study the effect of managerial time horizon on two key operations decisions: inventory levels and capacity investment. For identification, we exploit a quasi-natural experiment provided by the staggered adoption of constituency statutes, which alleviate managerial short-termism by providing legal protection to executives adopting a long-term approach in their corporate decisions. Using a staggered difference-in-differences design, we find that, after the reforms, firms incorporated in const...

摘要：Pirated video clips, a new form of piracy, have spread rapidly in recent years with the vigorous development of short-video social media platforms such as TikTok and Douyin. This has led to a huge loss of revenue for the film and TV drama industry where the negative economic impact trickles down from legitimate video platforms to content creators. As video platforms fight back against copyright infringement, they need to decide how much effort to invest in detecting and taking down pirated vid...

摘要：Patient features such as gender, age, and underlying disease are crucial to improving the model fidelity of surgery duration. In this paper, we study a robust surgery scheduling problem augmented by patient feature segmentation. We focus on the surgery-to-operating room allocations for elective patients and future emergencies. Using feature data, we classify patients into different types using machine learning methods and characterize the uncertain surgery duration via a feature-based cluster-...

摘要：We study a long-term service agreement (LTSA) between an original equipment manufacturer (OEM) of a conventional power generator and a utility firm in the electricity supply chain. The OEM offers the LTSA to the utility firm, which specifies the service fee and the maintenance interval. The utility firm dynamically chooses among different resources (conventional, renewable, or emergency) to meet energy demand. An LTSA contracts on a generator's long-term production schedule (i.e., the usage ti...

摘要：This study examines long-term care (LTC) discharge planning among older delayed discharge patients. While awaiting placements in alternate care such as LTC, these patients occupy hospital beds despite not requiring an intensive level of care. This study proposes a novel discharge decision model based on the Markov decision process (MDP) framework, which incorporates predictions regarding the patients' health trajectory and the associated hospital costs. Our machine learning (ML)-based predicti...

摘要：Nowadays, firms frequently use big data and pricing algorithms to offer consumers personalized prices according to their willingness to pay. Advances in information technologies have further facilitated the use of customized pricing, which we consider an important facet of transformative marketing. At the outset, personalized pricing may appear to reduce the asymmetry of information between the firm and consumers, and benefits the firm but hurts consumers. To investigate this view, we consider...

摘要：The United Nations Sustainable Development Goals have recently emphasized the importance of diversity inclusion. Motivated by this goal, we examine the impact of employing individuals with disabilities in apparel manufacturing cells on overall team productivity (PD). We formulate a series of deterministic and stochastic PD maximization assignment problems to study the impact of disability inclusion on a production line. We extend the baseline PD maximization formulation to study a multi-object...

摘要：Customers of many original equipment manufacturers (OEMs) in business-to-business markets today demand product servicizing in which instead of buying the product from the OEM they buy the use of a product during a lease. During the lease, (i) the customer uses the product and returns it to the OEM after the use reaches a specific level, (ii) the OEM remanufactures the product in a costly process and sends it back to the customer, and this usecycle is repeated multiple times. The lease terms ty...
