摘要：In today's competitive market environment, it is vital for companies to gain insight about competitors' new product launches. Past studies have demonstrated the predictive value of prerelease online search traffic (PROST) for new product forecasting. Relying on these findings and the public availability of PROST, we investigate its usefulness for estimating sales of competing products. We propose a model for predicting the success of competitors' product launches, based on own past product sal...

摘要：An increasing number of companies are using corporate online communities, a new information technology tool, to facilitate internal knowledge sharing. The corporate online community also offers companies a novel source to understand employee's behaviors such as voluntary turnover, an important part of workforce management. Little is known, however, about whether and to what extent an employee's voluntary turnover is related to their knowledge-sharing activities in the corporate online communit...

摘要：Reward-based crowdfunding is a form of innovative financing that allows project creators to raise funds from potential backers to start their ventures. A crowdfunding project is successfully funded if and only if the predetermined funding goal is achieved within a given time. We study the optimal timing of contingently placing a fulcrum in the random pledging process, with the potential of tilting it toward success, which would be a win-win for the creator, backers, and platform. Specifically,...

摘要：New technologies and innovative business models are leading to connected, shared, autonomous, and electric solutions for the tomorrow of urban transport and logistics (UTL). The efficiency and sustainability of these solutions are greatly empowered by the capability of understanding and utilizing the tremendous amount of data generated by passengers, drivers, and vehicles. In this study, we first review the innovative applications in UTL and several related research areas in the operations man...

摘要：Strategic customers typically patronize service systems at a higher rate than the socially optimal one. Much literature has focused on inducing customers to join such systems at this latter rate. This entire literature considers nonidling policies that are the focus of queueing theory. We demonstrate that strategically imposing delays into service systems can improve the social welfare using the M/G/1 queue with orbit. This versatile queueing model has been extensively studied from a performan...

摘要：This paper studies whether risky borrowing will induce a supplier to expand capacity and thus mitigate a capacity underinvestment problem in supply chains. It demonstrates that the relationship between capacity and capital structure is not as simple as the existing literature suggests. If the supplier is very powerful, it will use a mixed capital structure and build less capacity than if it were equity financed. If the buyer is very powerful, the supplier will use all debt financing and overbu...

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,...

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...

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...

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...
