摘要：Maliciously false information (disinformation) can influence people's beliefs and behaviors with significant social and economic implications. In this study, we examine news articles on crowd-sourced digital platforms for financial markets. Assembling a unique dataset of financial news articles that were investigated and prosecuted by the Securities and Exchange Commission, along with the propagation data of such articles on digital platforms and the financial performance data of the focal fir...

摘要：Online word-of-mouth studies generally assume that a product's average rating is the primary force shaping consumers' purchase decisions and driving sales. Similarly, practitioners place more emphasis on average ratings by displaying them at more salient places than individual reviews. In contrast, emerging evidence suggests that individual reviews also affect the decision-making of those consumers who consult both kinds of information. However, because average ratings and individual reviews a...

摘要：We study a dynamic job assignment problem in queueing systems with one class of Poisson arrivals and K groups of heterogeneous servers. A scheduling policy prescribes the job assignment among servers in each group at every state n (number of jobs in the system). Our goal is to obtain the optimal policy to minimize the long-run average cost, which involves the increasingly convex holding cost for jobs and the operating cost for working servers. This problem has wide application scenarios in ope...

摘要：We study an inventory placement optimization problem where demand is sensitive to service response time, under the online retailing setting. The main challenge is to achieve the optimal trade-off between revenue benefits from shorter delivery time and the increase in inventory cost associated with placing inventory closer to market demand. To predict the effects of modified demand under service response time variations, we introduce a demand prediction and elasticity model to quantify the sens...

摘要：In business-to-business (B2B) markets, salespeople often act as market-makers, connecting customers with suppliers while collaborating with other salespeople to form a complex network of relationships. The authors propose that in such a relationship network, the salesperson's social capital, or who they know, and transaction efficacy, or what they do, have direct and interactive effects on performance. To test the proposed model, the authors use a transaction-level dataset from a large brokera...

摘要：Platelets are perishable (5-7 day shelf life) blood products required for a variety of clinical treatments. In North America, hospitals typically procure platelet units from a central supplier. As such, the remaining shelf life of the delivered units could be subject to high uncertainty. Our work focuses on developing new models that leverage the increasingly available data from hospital information systems to prescribe ordering decisions in the presence of this uncertainty. Specifically, we c...

摘要：We study the joint pricing and inventory management problem in the presence of online customer reviews. Customers who purchase the product may post reviews that would influence future customers' purchasing behaviors. We develop a stochastic joint pricing and inventory management model to characterize the optimal policy in the presence of online reviews. We show that a rating-dependent base-stock/list-price policy is optimal. Interestingly, we can reduce the dynamic program that characterizes t...

摘要：Large-scale production of a new vaccine, such as the COVID-19 vaccine, is characterized by evolving demand and production yield uncertainties. Further, following its FDA approval for efficacy and safety, a vaccine may not even be manufacturable due to its low production yield and the resulting lack of profitability. To deal with those challenges in practice, a vaccine manufacturer can (stochastically) increase the uncertain yield of a vaccine prior to launching large-scale production by learni...

摘要：One of the most popular ways of shopping in an omnichannel retailing environment is buy-online-pickup-in-store (BOPS). Retailers often promise BOPS shoppers short in-store pickup ready times. We study fulfillment scheduling decisions of BOPS orders destined for a single store of a retailer. There are two fulfillment options for BOPS orders: they can be either processed at a fulfillment center (FC) and delivered to the store or processed at the store without needing delivery. There are two type...

摘要：R&D projects in small biotechnology firms frequently involve knowledge from multiple technical fields and research in different problem domains. An increase in project knowledge scope, defined as the number of technical fields an R&D project covers, can be challenging for resource-constrained small firms. These firms often rely primarily on their principal investigators (PIs), who act as heavyweight project managers in guiding project ideas to successful R&D outcomes. PIs also work concurrentl...
