摘要:Since the liberalization of power markets in Europe, almost all investments have required government subsidies. This demonstrates the failure of short-term markets to send the right price signals to investors, but other market failures have been brought to light, among which is market incompleteness. The literature has consistently shown the benefits of risk-sharing instruments to complete a market and boost investments in the absence of market power. Because of entry barriers and legacy asset...

摘要:We propose a new framework that unifies different fairness measures into a general, parameterized class of convex fairness measures suitable for optimization contexts. First, we propose a new class of order-based fairness measures, discuss their properties, and derive an axiomatic characterization for such measures. Then, we introduce the class of convex fairness measures, discuss their properties, and derive an equivalent dual representation of these measures as a robustified order-based fair...

摘要:This study explores the effective use of order-tracking information in dualsourcing inventory systems in both backlogging and lost-sales settings. Our inventory model features a normal source, comprising a two-stage tandem queue with Erlangdistributed processing times at each stage, and an emergency source that bypasses the first stage. We show that under certain conditions the optimal policy is characterized by two thresholds and one switching curve determined by the workload at the emergency...

摘要:Immediately following a major earthquake, reconnaissance surveys seek to assess structural damage throughout the region with the help of a limited number of on-ground inspections. The goal is to collect informative and representative data that will guide subsequent relief efforts. We formulate a new type of vehicle routing problem, in which vehicles are tasked with data collection, and the objective function measures data quality using a nonlinear, nonseparable experimental design criterion. W...

摘要:Apportionment is the problem of distributing h indivisible seats across states in proportion to the states' populations. In the context of the U.S. House of Representatives, this problem has a rich history and is a prime example of interactions between mathematical analysis and political practice. Grimmett suggests to apportion seats in a randomized way such that each state receives exactly its proportional share qi of seats in expectation (ex ante proportionality) and receives either left per...

摘要:In a single-parameter mechanism design problem, a provider is looking to sell some service to a group of potential buyers. Each buyer i has a private value vi for receiving this service, but a feasibility constraint restricts which buyers can be simultaneously served. Recent work in economics introduced (deferred-acceptance) clock auctions as a superior class of auctions for this problem due to their transparency, simplicity, and strong incentive guarantees. Subsequent work focused on evaluati...

摘要:In many real -world markets, participants have non -convex preferences, and the allocation problem needs to consider complex constraints. Electricity markets are a prime example, but similar problems appear in many markets, which has led to a growing literature on market design. Competitive equilibrium does not generally exist in such markets. Today, power markets use heuristic pricing rules based on the dual of a relaxed allocation problem. With increasing levels of renewables, these rules ha...

摘要:This paper investigates the seller's revenue -maximizing mechanism in the face of a customer who searches for outside alternatives over a finite horizon. The customer's utility from searches is modeled as a general function-referred to as the recall function-of the past search outcomes. Without observing the customer's valuation of the product or any realization of search outcomes, the seller can propose and commit to a contract with the customer before the search process begins. Under a gener...

摘要:We consider the problem of allocating a single type of resource with limited supply to distinct groups, each with a finite population and characterized by a unique reward and arrival rate. We develop a stochastic model and formulate the problem as a Markov decision process. We study the structural properties of the optimal value function and derive the optimal allocation policy. Contrary to the conventional approach of incrementally extending access to groups of lower priority over time, our f...

摘要:We explore the optimization of the middle-mile fulfillment process in the context of e-commerce. In collaboration with a prominent e-commerce retailer in North America specializing in electronics and computer products, we develop a stochastic optimization problem to demonstrate how an efficient middle mile can alleviate strain on the critical last mile, leading to cost reduction and improved performance. First, we prove that the optimal policy is of a state-dependent threshold type. However, c...
