• Coordinated charging station search in stochastic environments: A multiagent approach AI翻译

  摘要：Range and charge anxiety remain essential barriers to a faster electric vehicle (EV) market diffusion. To this end, quickly and reliably finding suitable charging stations may foster an EV uptake by mitigating drivers' anxieties. Here, existing commercial services help drivers to find available stations based on real-time availability data but struggle with data inaccuracy, for example, due to conventional vehicles blocking the access to public charging stations. In this context, recent works ...

  摘要：We propose and analyze a novel framework to understand the role of noninstrumental information sharing in service operations management, that is, information shared by the firm not to affect consumers' actions, but to better manage their experience in the firm's process. The operations of the firm are organized as a process, consisting of a sequence of tasks, each of random duration. The firm shares real-time information with the consumer about the progress of their flow unit in the firm's pro...
• To centralize or decentralize: Mergers under price and quality competition AI翻译

  摘要：This paper examines firms' post-merger integration (PMI) strategy under price and service-quality competition when facing either deterministic or stochastic demand. Although horizontal mergers are prevalent in practice and have been analyzed extensively in the literature, little attention has been paid to the choice of PMI level. We develop a game-theoretic model, in which multiple firms compete on price and service quality with either deterministic or stochastic demand, and two of them decide...
• Serving two masters? Optimizing mobile ad contracts with heterogeneous advertisers AI翻译

  摘要：Our research question is motivated by a real problem faced by an existing demand aggregator. The aggregator represents multiple advertisers, each of whom signs one of two types of contracts with the aggregator for bidding on an RTB (real-time bidding) platform. A quality contract occurs on a cost-per-impression (CPM, i.e., cost per thousand impressions) basis. The advertiser is promised a minimum number of impressions and pays a CPM that is a function of the targeting quality as measured by th...
• Constrained optimization of objective functions determined from random forests AI翻译

  摘要：In this paper, we examine a data-driven optimization approach to making optimal decisions as evaluated by a trained random forest, where these decisions can be constrained by an arbitrary polyhedral set. We model this optimization problem as a mixed-integer linear program. We show this model can be solved to optimality efficiently using pareto-optimal Benders cuts for ensembles containing a modest number of trees. We consider a random forest approximation that consists of sampling a subset of ...
• Collaboration-competition dilemma in flattening the COVID-19 curve AI翻译

  摘要：Testing for COVID-19 is a key intervention that supports tracking and isolation to prevent further infections. However, diagnostic tests are a scarce and finite resource, so abundance in one country can quickly lead to shortages in others, creating a competitive landscape. Countries experience peaks in infections at different times, meaning that the need for diagnostic tests also peaks at different moments. This phase lag implies opportunities for a more collaborative approach, although countr...
• Operations (management) warp speed: Rapid deployment of hospital-focused predictive/prescriptive analytics for the COVID-19 pandemic AI翻译

  摘要：At the onset of the COVID-19 pandemic, hospitals were in dire need of data-driven analytics to provide support for critical, expensive, and complex decisions. Yet, the majority of analytics being developed were targeted at state- and national-level policy decisions, with little availability of actionable information to support tactical and operational decision-making and execution at the hospital level. To fill this gap, we developed a multi-method framework leveraging a parsimonious design ph...
• Implementing trade-in programs in the presence of resale platforms: Mode selection and pricing AI翻译

  摘要：Resale platforms such as Swappa and ThredUP, which provide a channel for product-holders to sell used products, have become common. Interestingly, in the presence of resale platforms, some firms, such as Apple, set lower rebates for the trade-in-for-upgrade (TU) mode instead of implementing the trade-in-for-upgrade-and-cash (TUC) mode as Huawei does. In this paper, we build game-theoretical models to explore how a firm should adjust its trade-in strategy (e.g., choose pricing and mode selectio...
• Dynamic pricing and production control in a two-item make-to-stock system with flexible dual sourcing and lost sales AI翻译

  摘要：We consider a joint control of pricing and production in a two-item inventory system, where each item can be produced by its dedicated source or a shared flexible source, under the lost-sales setting. The demands of the two items are correlated. Due to the complexity caused by the lost-sales assumption and the interplay between pricing and production decisions, we show the optimal value function satisfies five structural properties under certain conditions. The optimal ordering and pricing pol...
• Impact of praise cashback strategy: Implications for consumers and e-businesses AI翻译

  摘要：This study focuses on a broadly adopted but largely underexplored cashback strategy, the praise cashback strategy (PCS), which aims to entice consumers to keep purchases and post positive online reviews. The literature acknowledges the impact of cashback strategies on consumers' purchase and review behaviors; however, it does not focus on how they affect consumers' return behaviors. Moreover, there are few studies on the effect of cashback strategies on consumer surplus and social welfare in t...
