摘要：Single-leg revenue management is a foundational problem of revenue management that has been particularly impactful in the airline and hotel industry: Given n units of a resource, for example, flight seats, and a stream of sequentially arriving customers segmented by fares, what is the optimal online policy for allocating the resource? Previous work focused on designing algorithms when forecasts are available, which are not robust to inaccuracies in the forecast, or online algorithms with worst...

摘要：Product bundling is a widely used selling strategy among multiproduct firms, yet designing and pricing bundles optimally remain a complex challenge. This paper addresses this fundamental issue by exploring the selection and pricing of a single bundle from a range of products. For instance, in the single bundle with the rest (SBR) framework, the bundle is optimally chosen and priced, whereas the remaining products are offered individually, collectively maximizing profit. We show that the SBR op...

摘要：Apportionment is the act of distributing the seats of a legislature among political parties (or states) in proportion to their vote shares (or populations). A famous impossibility proven by Balinski and Young shows that no apportionment method can be proportional up to one seat (i.e., quota) while also responding monotonically to changes in the votes (i.e., population monotone). Grimmett proposed to overcome this impossibility by randomizing the apportionment, which can achieve quota as well a...

摘要：We consider a practically motivated variant of the canonical online fair allocation problem: A decision maker has a budget of perishable resources to allocate over a fixed number of rounds. Each round sees a random number of arrivals, and the decision maker must commit to an allocation for these individuals before moving on to the next round. The goal is to construct a sequence of allocations that is envy-free and efficient. Our work makes two important contributions toward this problem: We fi...

摘要：This paper studies inventory management policies to improve the last-mile delivery of healthcare products in remote settings prone to supply chain disruptions. It is motivated by the need for a reliable and cost-effective delivery system to resupply new mosquito-repellent products to combat malaria in the Lake Tanganyika region of the Democratic Republic of the Congo. The primary delivery methods used to supply villages along Lake Tanganyika can become inoperable during periods of flooding, ma...

摘要：Motivated by practical considerations in machine learning for financial decision making, such as risk aversion and large action space, we consider risk-aware bandits optimization with applications in smart order routing (SOR). Specifically, based on preliminary observations of linear price impacts made from the Nasdaq TotalView-ITCH (NASDAQ ITCH) data set, we initiate the study of risk-aware linear bandits. In this setting, we aim at minimizing regret, which measures our performance deficit co...

摘要：We study optimal transport-based distributionally robust optimization problems in which a fictitious adversary, often envisioned as nature, can choose the distribution of the uncertain problem parameters by reshaping a prescribed reference distribution at a finite transportation cost. In this framework, we show that robustification is intimately related to various forms of variation and Lipschitz regularization even if the transportation cost function fails to be (some power of) a metric. We a...

摘要：We study dynamic pricing and resource allocation in large-scale service systems where multiple service units serve customers who are both price and delay sensitive. Customers are segmented into classes characterized by class-specific service rates and demand functions shaped by posted prices and estimated delays. To jointly optimize revenue and delay performance, we propose a family of state-dependent greedy heuristics that (i) assign dedicated service capacities to each customer class, and (i...

摘要：We consider an optimal liquidation model in which an investor is required to execute meta-orders during intraday trading periods, and his trading activity triggers child orders and endogenously affects future order flow, both instantaneously and permanently. Under the assumptions of risk neutrality and deterministic constants of the impact parameters, we provide closed-form solutions and illustrate the relationship between trading strategies and feedback effects. The optimal trading strategy i...
