摘要：Problem definition: We have witnessed a rapid rise of on-demand platforms, such as Uber, in the past few years. Although these platforms allow workers to choose their own working hours, they have limited leverage in maintaining availability of workers within a region. As such, platforms often implement various policies, including offering financial incentives and/or communicating customer demand to workers in order to direct more workers to regions with shortage in supply. This research examin...

摘要：Problem definition: We consider a setting where online advertisers seek to acquire impressions from an advertising exchange through a multitier network of intermediaries, and study the mechanisms offered by the ad exchange and intermediaries when the advertisers' values are private. Academic/practical relevance: As opposed to traditional manufacturer/retailer settings, intermediaries in display advertising auction off contingent goods that they purchase only if downstream buyers signal interes...

摘要：Policy modeling refers to the application of operations research and allied quantitative methods to model policy problems. The idea is to help make better policy choices when data are uncertain or unavailable, the time allowed for analysis is very short relative to the natural time scale of the problem, or other resources seemingly necessary for analysis are constrained. This article reviews some personal adventures in policy modeling with attention to problem introduction, the role of operati...

摘要：Problem definition: In this paper, we identify the unique challenges and trade-offs in hydro system development for developing countries and provide a supply chain perspective to expand these countries' hydro networks for energy, irrigation, and flood control. Academic/practical relevance: The interconnected issues of water, energy, food, and flood are among the most formidable challenges faced by developing countries worldwide. The development of hydro systems has the potential to address all...

摘要：Problem definition: In a supply network consisting of a buyer, a purchasing agent, and a supplier, the buyer can procure the component from the supplier directly and rely on the purchasing agent for complementary services (named direct sourcing (DS)) or authorize the purchasing agent to conduct both procurement and complementary services (named agent sourcing (AS)). When parties bargain pairwisely, how do their bargaining powers influence the equilibrium procurement outsourcing structure? Acad...

摘要：Problem definition: Merchant commodity and energy production assets operate in markets with volatile prices and exchange rates. Plant closures adversely affect societal entities beyond the specific plant being shut down, such as the parent company and the local community. Motivated by an aluminum producer, we study if mitigating these hard-to-assess broader impacts of a shutdown is financially viable using the plant's operating flexibility. Academic/practical relevance: Our social commerce per...

摘要：Problem definition: Buyers can encourage competition among multiple suppliers of goods or services by redistributing their shares of the business based on recent observable performances. This is usually needed because actual efforts or investments by suppliers are typically unobservable, a moral hazard issue. This poses the problem: How should such redistribution be linked to the suppliers' recent performances to motivate the best supplier performance? Academic/practical relevance: Such perfor...

摘要：Problem definition: Are consumer product returns largely a function of retailers' return policies, or can manufacturers influence them through production characteristics and product attributes? How do operational levers under a manufacturer's control affect return rates? Academic/practical relevance: Consumer returns raise major questions for manufacturers and retailers because losses related to returns are substantial. However, levers commonly used to discourage returns, such as strict return...

摘要：Problem definition: Major hospitals frequently lack adequate space to accommodate emergency patients. Managers can take actions to create surge capacity, an immediate additional supply of medical services to accommodate increased demand. We study operational strategies that improve surge capacity, and we identify how they can be most effectively deployed based on the characteristics of individual hospitals. Academic/practical relevance: Recent government regulations in the United States have i...

摘要：Problem definition: In this paper, we study a reliable hub location model, the objective of which is to minimize the associated costs plus the penalty for unserved demands. The model assigns to each origin-destination pair a primary path and a backup path to hedge against the risk of random disruptions. Aside from the fixed costs of locating hubs, the fixed costs incurred by hub-connecting arcs that exhibit economies of scale in transportation are considered. Academic/practical relevance: The ...
