摘要：We consider the problem of dynamic pricing in the presence of patient consumers. We call a consumer patient if she is willing to wait a certain number of periods for a lower price and will purchase as soon as the price is equal to or below her valuation. We allow for arbitrary joint distributions of patience levels and valuations. We propose an efficient dynamic programming algorithm for finding optimal pricing policies. We find numerically that optimal policies can take the form of incomplete...

摘要：Motivated by call center practice, we propose a tractable approximate model for queues with general service and patience time assumptions in the efficiency-driven (ED) regime, when customers' patience times are relatively long compared with their service times. We use a one-dimensional diffusion process to approximate the virtual waiting time process that is scaled in both magnitude and time, with the number of servers and the mean patience time as the respective scaling factors. Using this di...

摘要：We study the problem of dynamic assortment personalization with large, heterogeneous populations and wide arrays of products, and demonstrate the importance of structural priors for effective, efficient large-scale personalization. Assortment personalization is the problem of choosing, for each individual (type), a best assortment of products, ads, or other offerings (items) so as to maximize revenue. This problem is central to revenue management in e-commerce and online advertising where both...

摘要：In classical newsvendor games, vendors collaborate to serve their aggregate demand whose joint distribution is assumed known with certainty. We investigate a new class of newsvendor games with ambiguity in the joint demand distributions, which is represented by a Frechet class of distributions with some, possibly overlapping, marginal information. To model this new class of games, we use ideas from distributionally robust optimization to handle distributional ambiguity and study the robust new...

摘要：We consider an infinite-horizon lost-sales inventory model where the supply takes positive lead times and is a random function of the order quantity (e.g., random yield/capacity). The optimal policy for this model is computationally intractable, and no heuristic has been proposed in the literature. In this paper, we focus on a simple class of constant-order policies (COPs) that place the same order in every period regardless of the system state. Under some assumptions on the random supply func...

摘要：There are different workforce models in the gig economy. Although some ondemand service providers rely strictly on either traditional employees or independent contractors, others rely on a blended workforce, which melds a layer of contingent workers with a core of permanent employees. In deciding on the right number of right people to staff at the right time, managers must appropriately weigh the pertinent tradeoffs. In this paper, we study cost-minimizing staffing decisions in service systems...

摘要：Most results in revenue-maximizing mechanism design hinge on getting the price right-selling goods to bidders at prices low enough to encourage a sale but high enough to garner nontrivial revenue. This approach is difficult to implement when the seller has little or no a priori information about bidder valuations or when the setting is sufficiently complex, such as matching markets with heterogeneous goods. In this paper, we apply a robust approach to designing auctions for revenue. Instead of...

摘要：We study the fluid model of a many-server queue with multiple customer classes and obtain optimality results for this model. For the purpose of minimizing the long-run average queue-length costs and abandon penalties, we propose three scheduling policies to cope with any general cost functions and general patience-time distributions. First, we introduce the target-allocation policy, which assigns higher priority to customer classes with larger deviation from the desired allocation of the servi...

摘要：Passes are prepaid packages of multiple units of goods or services with flexible consumption times. They may take a variety of forms such as commuter passes in transportation, capped quotas in telecommunications, or memberships in health or beauty clubs. We consider a monopolist selling products or services to strategic customers by dynamically pricing passes in conjunction with individual items. The strategic behavior is captured by a dynamic choice model that endogenizes strategic purchase, ...

摘要：Pricing over multiple periods under forward-looking, strategic consumer purchasing behavior has received significant recent research attention; however, whether consumers actually benefit from this behavior and would voluntarily choose to be strategic has not been previously considered. We explore this question by developing a model of endogenous time preferences, consistent with microeconomic theories of boundedly rational intertemporal decision making, in which consumers choose to become str...
