  摘要：Advances in machine learning methods and the availability of new data sources show promise for improving prediction of operational risk. Maritime transportation is the backbone of global supply chains and maritime accidents can lead to costly disruptions. We describe a case study performed for the United States Coast Guard (USCG) to develop a prototype risk prediction system to provide early alerts of elevated risk levels to vessel traffic managers and operators in the Lower Mississippi River,...
• Consumer Choice Models and Estimation: A Review and Extension AI翻译

  摘要：Choice models are widely applied in psychology, economics, transportation, marketing, and operations studies. We review the existing developments on the modeling of consumers' choices, including the attraction model, the utility-based model, the temporal model, and the rank-based model. The relationships among different classes of structural models are established and analyzed. Moreover, an operational data analytics (ODA) framework is presented to estimate the general consumer choice model us...
• Managing Stochastic Bucket Brigades on Discrete Work Stations AI翻译

  摘要：Bucket brigades are notably used to coordinate workers in production systems. We study a J-station, I-worker bucket brigade system. The time duration for each worker to serve a job at a station is exponentially distributed with a rate that depends on the station's expected work content and the worker's work speed. Our goal is to maximize the system's productivity or to minimize its inter-completion time variability. We analytically derive the throughput and the coefficient of variation (CV) of...
• Scalability in Platforms for Local Groceries: An Examination of Indirect Network Economies AI翻译

  摘要：Despite a significant rise in consumer interest in local foods, supply constraints limit access to these products in many markets. Online platforms for local foods may help solve these constraints. However, to our knowledge, there is no empirical research on the economic viability of these platforms. We study this problem by analyzing a two-sided platform subject to indirect network effects. If present, these effects will create a virtuous cycle where consumers' demand for products sold throug...
• Sustainable humanitarian operations: An integrated perspective AI翻译

  摘要：The immediate response to disasters, while well intended, sometimes causes avoidable humanitarian challenges later on. Drinking water may be essential, but it is not necessary to provide it in small plastic bottles. Injections may save lives, but inappropriately discarded syringes are hazardous. Can humanitarian relief be made more sustainable? This paper summarizes a 1-day workshop on this topic, held at INSEAD in 2019 in connection with Luk Van Wassenhove's transition to emeritus professor. ...
• Managing contributor performance in knowledge-sharing communities: A dynamic perspective AI翻译
  作者：Jin, Yue; Tan, Yong; Huang, Jinghua

  摘要：Knowledge sharing has become an important practice in the era of knowledge economy. This paper concerns the management of contributor performance in social knowledge-sharing communities. Based on ability-motivation-opportunity theory, we propose a hidden Markov model to characterize the change in a knowledge contributor's latent state, which then determines the performance of knowledge sharing in terms of quantity and quality. The proposed model is calibrated using data from a social question-...
• Toward the understanding of the constituents of organizational culture: The embedded topic modeling analysis of publicly available employee-generated reviews of two major US-based retailers AI翻译
  作者：Gupta, Manjul; Gupta, Amulya; Cousins, Karlene

  摘要：Organizational culture is considered an important factor affecting several operations-oriented functions in an organization. However, the research surrounding organizational culture and what constitutes organizational culture remains understudied in the operations management (OM) discipline. This study utilizes 24,965 employee-generated (EG) text reviews of two major U.S.-based retailers and applies an advanced embedded topic modeling technique to identify prevalent cultural elements that reta...
• Is it all about you or your driving? Designing IoT-enabled risk assessments AI翻译

  摘要：Technological applications disrupt the way to assess risks in the auto-insurance business. Contrasted with the common practice based on static demographics, usage-based insurance predicts risks using driving data collected from Internet-of-things-enabled telematics. This study proposes a novel solution leveraging the synergy between big data and hierarchical modeling. We specifically consider two aspects of mobility, namely, trait and trajectory, monitored by global positioning system (GPS), o...
• Dynamic scheduling of home care patients to medical providers AI翻译
  作者：Cire, Andre A.; Diamant, Adam
  作者单位：University of Toronto; University Toronto Scarborough; York University - Canada
  摘要：Home care provides personalized medical care and social support to patients within their own homes. Our work proposes a dynamic scheduling framework to assist in the assignment of health practitioners (HPs) to patients who arrive stochastically over time and are heterogeneous with respect to their health requirements, service duration, and region of residence. We model the decision of which patients to assign to HPs as a discrete-time, rolling-horizon, infinite-stage Markov decision process. D...
• Optional purchase verification in e-commerce platforms: More representative product ratings and higher quality reviews AI翻译

  作者单位：Boston College; Athens University of Economics & Business
  摘要：E-commerce platforms struggle to create and maintain high-quality reputation systems. One promising option is purchase verification, which confirms that the user reviewing a product purchased the product from the platform. Previous works comparing platforms that require purchase verification with platforms that do not offer purchase verification found that review manipulation is easier in the latter. But what happens in platforms where purchase verification is optional? In such platforms, ther...
