摘要：We study the widespread practice of assigning a single surgeon to two operating rooms (ORs), which is known as overlapping surgery. We first describe the fundamental trade-offs that motivate hospitals to employ the practice. Then, we conduct a mathematical analysis for the completion of a set of elective operations under an overlapping surgery policy and a more traditional, serial scheduling policy. We use this analysis, along with a cost function that considers surgeon idle time and total OR ...

摘要：Performance measures of control charts with estimated parameters are random variables and vary significantly across reference samples. In this context, a recent idea has been to study the distribution of the realized (or conditional) in-control average run length (CARL(0)) [or, equivalently, the conditional false-alarm rate (CFAR)] for a set of estimates from a given reference sample and apply the exceedance probability criterion (EPC) to design control charts that ensure a desirable in-contro...

摘要：Cloud providers such as Amazon, IBM, and Microsoft are leasing their computing resources to various businesses providing them an alternative to investing in expensive hardware. Although recent information systems research has examined pricing-related issues in cloud computing, several important questions still remain. For example, how should buyers decide on the capacity portfolio of private and public clouds? What is the impact of the buyer's demand uncertainty on the capacity portfolio decis...

摘要：Despite our understanding that social media and online healthcare communities can help to eliminate health information asymmetry and improve patients' self-care engagement, we have yet to understand what happens when patients have access to others' health data and how patients' access to these shared experiences and opinions influence their health knowledge and perceived treatment outcome. In this study, we apply social information processing theory and incorporate (1) uncertainty of a treatme...

摘要：We analyze a brand's disclosure of its supplier list to improve the suppliers' compliance with social and environmental sustainability standards. We develop a model of a buyer, a supplier, and an NGO; when a violation of the supplier occurs, the buyer and the supplier both incur penalties. Given that the disclosure influences the NGO's perception of the supplier and results in a different level of NGO scrutiny, the buyer decides whether to reveal her supplier. Our model characterizes the buyer...

摘要：The study Mitigating the U.S. Drug Shortages Through Pareto-Improving Contracts was selected as a runner-up for the Ralph Gomory Best Industry Studies Paper Award by the Industry Studies Association in 2017. The award aims at explicit recognition of the researchers' engagement with industry practitioners and demonstrate the benefits of such interactions for scholarly research. The awarded study addresses the drug shortages problem, a major challenge facing the U.S. pharmaceutical industry and ...

摘要：Consumers often have needs that change in a dynamic fashion over time due to physiological, mental, or environmental variations. We develop a model to address a product strategy question on how to satisfy dynamic consumer preferences: Should a firm offer multiple standard products, each designed for a specific purpose (e.g., several specialized golf clubs), or a flexible product that can be reconfigured by consumers as their preferences change (e.g., one adjustable golf club)? Often the latter...

摘要：This study examines the strategic choices of two rival manufacturers between competition and coopetition. A complex relationship exists between these two firms, who manufacture substitutive products. In addition, each of these firms has an option to purchase (or sell) a key component from (or to) the other. We develop a benchmark competition model and two coopetition models in which the manufacturers compete for end-customer demand while simultaneously collaborating on component production thr...

摘要：This study examines the relationship between exogenous demand shock and market structure in India's influenza vaccine markets. Using a novel dataset of detailed purchasing information for vaccines in India, and exploiting the 2009-10 global H1N1 pandemic as an exogenous demand shock, we provide evidence of heterogeneous responses to the shock by domestic and multinational vaccine manufacturers in the influenza vaccine market relative to our control group of all other vaccine markets. We find t...
