摘要：Problem definition: We present a continuous-time Bayesian model for managing inventory in a retail setting when inventory records are inaccurate. In our formulation, the inventory level and its record have separate dynamics. The former is driven by the demand and unobservable loss process, whereas the latter is driven by the demand and transaction error process. Methodology/results: We analytically characterize the dynamics of the retailer's belief on the shelf inventory level and prove that t...

摘要：Problem definition: Companies operating global supply chains face growing policy uncertainties that affect the costs of importing raw materials (RM) and finished goods (FG) from low-cost to developed countries, as well as the relative profitability of production in different countries. This has prompted the need for diversified global supply chains often involving the addition of onshore production alongside existing offshore facilities. Motivated by recent developments in the U.S. clean energ...

摘要：Problem definition: The adoption of online services, such as telemedicine, has increased rapidly over the last few years. To better manage online services and effectively integrate them with in-person services, we need to better understand customer behaviors under the two service modalities. Utilizing data from two large internal medicine outpatient clinics, we take an empirical approach to study service incompletion, which can be because of either patient no-show or leaving without being seen...

摘要：Problem definition: In the user-generated content (UGC) business model, the platform provides income for the creators, the creators provide content for the viewers, and the viewers provide advertising revenue for the platform, forming a relationship triangle. We set out to study a UGC platform's optimal dynamic operational policies in its different stages and the impact of various constraints and innovations. Methodology/results: We adopt a hybrid of the Bass diffusion model and the replicator...

摘要：Problem definition: Micromobility systems (bike-sharing or scooter-sharing) have been widely adopted across the globe as a sustainable mode of urban transportation. To efficiently plan, operate, and monitor such systems, it is crucial to understand the underlying rider demand-where riders come from and the rates of arrivals into the service area. They serve as key inputs for downstream decisions, including capacity planning, location optimization, and rebalancing. Estimating rider demand is no...

摘要：Problem definition: An online retailer selling a perishable product can issue inventories of different remaining lifetimes in its preferred sequence. This creates a tradeoff between customer satisfaction and outdating costs since customers want freshness, whereas the retailer desires units be sold within their lifetime. We study this trade-off by considering a joint replenishment and issuance policy for a perishable product with a general lifetime. Methodology/results: We develop a periodic re...

摘要：Problem definition: This paper investigates the effectiveness of emission permits policies with varying levels of temporal flexibility, including different compliance periods and the allowance/prohibition of intertemporal banking and borrowing. We also explore advanced policy designs aimed at improving social welfare. Methodology/results: Our analysis reveals that extreme policies, such as fully flexible or fully nonflexible permits, are generally suboptimal from a welfare perspective. Restric...

摘要：Problem definition: Whereas artificial intelligence (AI) algorithms may perform well on data that are representative of the training set (inliers), they may err when extrapolating on nonrepresentative data (outliers). How can humans and algorithms work together to make better decisions when faced with outliers and inliers? Methodology/ results: We study a human-AI collaboration on prediction tasks using a bias adjustment framework and hypothesize that humans tend toward na & iuml;ve adjusting ...

摘要：Problem definition: To generate more sales, retailers are incentivized to open large stores. However, large store formats can carry negative environmental externalities. Entry of large stores in a community may stimulate mass consumption through its impact on consumer behaviors and local competition. In this study, we examine the local impact on the amount of consumer waste generated following an expansion of retail Supercenters. Methodology/results: We leverage the staggered expansion of Walm...
