摘要：Problem definition: We study how clinical teams adaptively respond to realtime deviations from the planned operating room (OR) schedules and the associated consequences of these responses. Specifically, we explore whether clinical personnel adjust their service speed when they are ahead of or behind the original schedule and whether this affects patient reoperation rates. We then analyze the complicated relationships between OR schedules, patient wait times, and reoperations to offer recommend...

摘要：Request-for-quote (RFQ) is the most commonly used mechanism for contractor selection in project outsourcing. Problem definition: We study how RFQ design interacts with the time-cost trade-off in project execution and compare two common contract forms: time-incentive contracts (penalizing lateness) and cost-sharing contracts (reimbursing direct costs). Methodology/results: Using a game-theoretic model, we characterize optimal RFQ designs under incomplete information about contractors' direct co...

摘要：Problem definition: Motivated by the significance of side information in numerous operations management problems, this paper studies conditional stochastic optimization to enable more informed decisions. The side information constitutes observable exogenous covariates that alter the conditional probability distribution of the random problem parameters. Decision makers who adapt their decisions according to the observed side information solve a stochastic optimization problem where the objectiv...

摘要：Problem Definition: This study examines a seller's joint information disclosure and pricing decisions when launching a new product with an easy-to-communicate objective attribute and a hard-to-describe subjective attribute. We analyze how consumer search cost, inventory level, and channel structure shape the seller's optimal information strategy. Results: For brick-and-mortar retailing, the seller should conceal (disclose) attribute information when the search cost is low (high). Interestingly...

摘要：Problem definition: This work investigates the effect of technological monitoring on salesforce efficacy. While prior research has investigated the creation of incentive packages to resolve the principal-agent problem, the efficacy of increasingly inexpensive and widely available technological monitoring has received less attention. We argue that the effect of such programs on salesperson performance is ambiguous. On the one hand, such programs may increase performance by increasing transparen...

摘要：Problem definition: We propose a feature-based consideration set choice model (FCM) motivated by customers' purchasing behavior in online retail platforms. In our model, customers form a consideration set by including products with the highest utilities computed based on a subset of product features visible on the search results page. The customers then make a purchase decision from the consideration set by accounting for all features available on the product pages. The FCM incorporates hetero...

摘要：Problem definition: Global supply chains are currently experiencing unprecedented challenges arising from a shift toward deglobalization in international trade policies. This trend has resulted in the tightening of rules of origin (ROOs) within regional trade agreements, placing pressure on firms to localize or nearshore their production activities. In this paper, we explore how firms' global sourcing decisions respond to these changes in trade policies by utilizing the tightening of automotiv...
