  摘要：In fashion, food processing, petrochemical production, and agriculture, products (items) are often bundled in a prefixed assortment, with a given ratio for each product. For example, one case of men's shoes may contain 24 pairs of different sizes of the same design. Of the 24 pairs, there is one size 7 pair, four sizes 9, and so on. Moreover, those pairs of shoes are packaged independently for retailing. Retailers of such products order them in bundles and then resell them unbundled. In this s...
• Rationally Trust, but Emotionally? The Roles of Cognitive and Affective Trust in Laypeople's Acceptance of AI for Preventive Care Operations AI翻译

  摘要：Artificial intelligence (AI) is transforming healthcare operations. Nevertheless, particularly in the context of preventive care, little is known about how laypeople perceive and accept AI and change their behavior accordingly. Grounded in a solid theoretical framework of trust, this study bridges this gap by exploring individuals' acceptance of AI-based preventive health interventions and following health behavior change, which is critical for preventive care providers' operational and busine...
• Team Composition and Incentive Design in Collaborative Product Development AI翻译

  摘要：Choosing the right development team is crucial for companies. We investigate how project collaboration requirements and uncertainty levels affect the choice between specialists with higher levels of task-specific abilities and generalists with higher levels of collaboration skills. We also examine how these factors affect optimal team incentives. In addition to performance-enhancing helping, we consider another type of collaboration that has received less attention in the incentive literature:...
• When Costco Comes to Town, Can Adjusting Product Variety Shield Incumbent Stores From Sales Loss? Insights From Retail Collocation, Category, and Preexisting Competition AI翻译

  摘要：When a competitor enters a market, incumbent retail stores often adjust their product variety to avoid sales loss. However, no empirical evidence has been provided in the literature to justify the value of such product variety adjustments after a rival's entry. One difficulty is that the change in consumer demand due to rival's entry and changes in product variety simultaneously affect incumbents' sales. When changes in sales at incumbent stores are observed after rivals' entries, it is unclea...
• Joint planning and operations of wind power under decision-dependent uncertainty AI翻译
  作者：Chen, Zhiqiang; Xu, Wei; Chen, Caihua; Cui, Jingshi; Hu, Qian

  摘要：We study a joint wind farm planning and operational scheduling problem under decision-dependent uncertainty. Geographic heterogeneity in wind power resources induces stochastic fluctuations that can partially offset one another-a phenomenon known as the smoothing effect. Capturing this effect requires strategic capacity allocation, which introduces decision-dependent uncertainty. At the same time, joint planning and operations must address long-term complexity, where traditional stochastic opt...
• Enhancing electric vehicle charging station design using multifidelity simulations AI翻译

  摘要：We study simulation-assisted service system design, where stochastic simulation is used to select the best design from a finite set of structural or parametric alternatives. Since high-fidelity simulation can be prohibitively time-consuming, we adopt a multifidelity approach that combines expensive high-fidelity runs with cheaper, coarser low-fidelity runs to estimate system performance and compare designs. This research is motivated by the design of an integrated electric vehicle (EV) fast-ch...
• Research opportunities in wildfire management from an Operations Management perspective AI翻译

  摘要：Wildfires-also known as wildland fires, bushfires, and forest fires-are large-scale, uncontrolled fires that occur in vegetated areas, triggered by natural or human causes. They have significant economic, environmental, and social impacts. As with most disasters, the location, timing, and magnitude of wildfires are unpredictable. Wildfire management (WFM) has a long history in forestry research; however, it remains relatively underexplored by Operations Management (OM) researchers, partly due ...
• Manufacturer Encroachment in the Presence of Production Economies of Scale AI翻译

  摘要：It is well established that a manufacturer generally benefits from encroachment with a profitable direct channel and may also benefit from using encroachment as a threat (i.e., without sales in the direct channel); the retailer may also benefit from both encroachment strategies. Our study provides new insights into the manufacturer encroachment literature by considering the upstream manufacturer's production economies of scale. Contrary to conventional wisdom, we show that an increasing level ...
• Impact of Recreational Marijuana Legalization on Hotel Performance and Operations: A Bayesian Causal Inference Approach AI翻译

  摘要：This article investigates the effects of legalizing recreational marijuana dispensaries on hotel performance and operations using Bayesian causal inference within the potential outcomes framework. Focusing on Colorado, the study finds that, on average, hotel revenue increases by 25.2% (or $63,671 monthly) due to dispensary legalization, with the effect continuing to grow even 6 years after legalization. The revenue boost arises from a 7.9% increase in room night bookings and a 16.0% rise in da...
• Optimality of Base-Stock Policy Under Unknown General Demand Distributions: New Methods, New Results, and Computations AI翻译

  摘要：This article advances the literature on the optimality of the base-stock policy for a general demand distribution and a general prior belief, which we update as we observe realized demands, assumed to be continuous, independent and identically distributed, random variables. The value function depends on the belief, so the functional Bellman equation is infinite-dimensional. Significantly, in contrast with traditional approaches, we derive a functional equation for the derivative of the value f...
