摘要：We consider dynamic pricing with covariates under a generalized linear demand model: A seller can dynamically adjust the price of a product over a horizon of T time periods, and at each time period t, the demand of the product is jointly determined by the price and an observable covariate vector xt is an element of Rd through a generalized linear model with unknown coefficients. Most of the existing literature assumes the covariate vectors xts are independently and identically distributed (i.i...

摘要：To enhance supply chain resilience, assembly manufacturers increasingly adopt dual-sourcing strategies, utilizing both regular and faster but costlier express sources for each key component. Although research has focused on single-item systems, coordinating dual-sourced orders across multiple components in an assembly system remains underexplored. To address this gap, we introduce a novel Critical-Set Base-Surge (CSBS) policy, which combines a constant order policy for regular sources to meet ...

摘要：Vehicle sharing systems, such as those for bicycles, scooters, and cars, are fundamental to serve transportation needs. Companies that operate these systems set prices (or fares) using algorithms to determine how much a user must pay and display the fares through mobile applications. This may result in users from different locations paying different prices for a vehicle. Moreover, the overall accessibility of these systems may be very different depending on the user's location. Platforms and r...

摘要：One of the main results of Yu and Kong [Yu and Kong (2020) Robust contract designs: Linear contracts and moral hazard. Oper. Res. 68(5):1457-1473] is proposition 4, which states that the optimal robust contract with a piecewise linear concave agent utility only consists of progressive fixed payments and linear rewards with progressive commission rates. In this note, we present a proof-based counterexample to theoretically demonstrate the incorrectness of this result. We then perform a numerica...

摘要：Matching demand (riders) to supply (drivers) efficiently is a fundamental problem for ride-sharing platforms that need to match the riders (almost) as soon as the request arrives with only partial knowledge about future ride requests. A myopic approach that computes an optimal matching for current requests ignoring future uncertainty can be highly suboptimal. In this paper, we consider a two-stage robust optimization framework for this matching problem in which future demand uncertainty is mod...

摘要：We study optimization for data-driven decision making when we have observations of the uncertain parameters within an optimization model together with concurrent observations of covariates. The goal is to choose a decision that minimizes the expected cost conditioned on a new covariate observation. We investigate two data-driven frameworks that integrate a machine learning prediction model within a stochastic programming sample average approximation (SAA) for approximating the solution to this...

摘要：Traditional queuing theory assumes that job types are perfectly observed and assigns each job to a type-specific priority queue-an approach we term type-driven priority queuing. We study feature-driven priority queuing, where types are unobserved and must be inferred from observable features using a classifier. We examine two implementations. The first, type-first, predicts type probabilities from features and then maps these probabilities to priority queues. The second, direct, bypasses type ...

摘要：There has been a notable surge of online platforms that operate as market facilitators without having direct control over the inventory of the products they sell. When an online platform operates as a market facilitator, the products offered to a customer may have a significant probability of being out of stock when the order placed by the customer is being fulfilled. Therefore, such online platforms often prompt the customers to pick not only a preferred option, but also a replacement option,...

摘要：We introduce and study the online Bayesian recommendation problem for a recommender system platform. The platform has the privilege to privately observe a utilityrelevant state of a product at each round and uses this information to make online recommendations to a stream of myopic users. This paradigm is common in a wide range of scenarios in the current internet economy. The platform commits to an online recommendation policy that utilizes its information advantage on the product state to pe...

摘要：Shared rides, which pool individual riders into a single vehicle, are essential for mitigating congestion and promoting more sustainable urban transportation. However, major ridesharing platforms have long struggled to maintain a healthy and profitable shared rides product. To understand why shared rides have struggled, we analyze procedures commonly used in practice to set static prices for shared rides and discuss their pitfalls. We then propose a pricing policy that is adaptive to matching ...
