摘要:Problem definition: Determining the optimal length of stay (LOS) and posttreatment location is critical for hematology-oncology (blood cancer) patients, who are highly vulnerable to life-threatening infections. Early discharge to home care reduces infection risk, whereas extended hospital observation minimizes mortality risks if an infection occurs. We address this trade-off by developing LOS optimization models tailored to these patients. Methodology/results: We develop a newsvendor-type mode...

摘要:Problem definition: This paper investigates how governments can design optimal public health policies to inform and guide the public amid uncertain health threats. To capture heterogeneity in social behavior, we introduce a class of socializing agents and examine how the government strategically combines two policy instruments-persuasive communication (messages) and physical or monetary penalties-to incentivize compliance with social restrictions. Methodology/results: We develop a game-theoret...

摘要:Problem definition: We study optimal integrated inventory and pricing decisions for substitutable products over a finite planning horizon with full backlogging and nonstationary costs and demands. The objective is to maximize the total expected discounted profit. Methodology/results: We present a unified demand model that encompasses many commonly used models in the literature. We show that the dynamic optimization problem is jointly concave in inventory and market-share vectors. This enables ...

摘要:Problem definition: Collaboration among care providers is critical to healthcare delivery, yet its impact on inpatient service times-especially at the interpersonnel level- remains unclear. Prior work has focused on team familiarity or shared experience. In contrast, we examine collaboration, which is defined as real-time coactivity during an inpatient stay. This study explores the nonlinear effects of collaboration on service time, focusing on weak initial collaboration, strengthening dynamic...

摘要:Problem definition: A firm's stakeholders would benefit from a quantitative measure of the managerial disclosure of its operational risk and the implications of this disclosure. However, a quantitative and scalable measure of a firm's disclosed operational risk is unavailable. Thus, the firm's stakeholders remain unaware of its disclosed operational risk and the risk's implications. Methodology/results: U.S. law requires a public firm to textually disclose its operational and nonoperational ri...

摘要:Problem definition: Personalized product recommendations are crucial for online platforms but pose privacy risks. To address these concerns, we propose recommendation policies that adhere to differential privacy constraints. Methodology/results: We develop a theoretical model where the recommendation policy selects products based on consumers' preference rankings, learned from personal data. Unlike conventional recommendation policies that primarily focus on prospering from meeting consumer sa...

摘要:Problem definition: As digitization transforms the service sector and empowers service platforms, questions arise about utilizing and disseminating customer information captured by digitization to enhance platform operations. We contribute by investigating how providing customer-related information at the start of a service encounter impacts both service supply and demand in the context of entertainment service platforms. Methodology/ results: We conducted a field experiment on a live-streamin...

摘要:Problem definition: Emissions from diesel semitrucks, such as nitrogen oxides, have contributed significantly to air pollution, prompting government intervention. However, directly regulating trucking companies' diesel truck usage often falls outside the jurisdiction of local governments. A legislative alternative is to regulate other sectors within the local region that indirectly drive diesel truck usage, referred to as indirect emission sources. The first of such regulations is Southern Cal...

摘要:Problem definition: We study assortment optimization problems with market share constraints. The products are partitioned into product classes, each with a market share threshold. If a product class is represented in the offered assortment, then the total purchase probability of the products offered in the class should be above the market share threshold of the product class. Customers choose among offered products according to the multinomial logit model. The goal is to maximize the expected ...

摘要:Problem definition: Extensive evidence shows that customers tend to underestimate the variability of service times. The theoretical foundation lies in overconfidence theory, which asserts that decision makers tend to make overly optimistic forecasts about uncertain events. We study how to decide optimal pricing and queue-length information provision policies to manage a service system where customers are overconfident in their beliefs about service times-customers underestimate the variability...
