  摘要：How do firms respond after being exposed to a low-probability, high-consequence (lp-hc) disruption event? This study examines inventory and flexibility patterns in manufacturing firms in the years following an lp-hc event, the Great East Japan Earthquake of 2011. We find patterns suggesting that most firms exposed to the event began to increase their raw material inventories (RAW) over the longer term and increased their volume flexibility for a shorter period. Furthermore, we found that firms...
• Implications of vaccine shopping during pandemic AI翻译

  摘要：Many individuals have strong preferences regarding COVID-19 vaccines and would like to choose the vaccine they get. This practice, known as vaccine shopping, presents unique challenges to timely vaccine rollout: On the one hand, people may not get vaccinated if they are unable to receive their preferred vaccine, and on the other hand, a policy maker is inclined to distribute vaccines in a brand agnostic fashion to avoid wastage. We study whether a policy maker should allow individuals to choos...
• Discrete-item inventory control involving unknown censored demand and convex inventory costs AI翻译

  摘要：We study inventory control involving lost sales and hence censored demand. In a long-run average framework, the demand distribution is largely unknown. As long as the stationary inventory costs are strictly convex to the extent that the second lost item costs strictly more than the first one, the regret would be Omega(T-2/3). Our discrete-item setting has rendered the presence or absence of strong censoring indicators or equivalently, being knowledgeable or ignorant of one more demand request ...
• The influence of trauma on internal integration: An approach-avoidance analysis in disaster relief operations AI翻译

  摘要：Disaster relief workers face unique factors in their operating environments that can inhibit internal integration. For example, disaster relief often involves exposure to traumatic events affecting relief workers' commitment to cooperation and the organization. As such, disaster relief organizations dedicate substantial amounts of scarce resources to support workers exposed to trauma. Unfortunately, contradictory views exist in the literature on how trauma exposure affects commitment and integ...
• Fair and efficient vaccine allocation: A generalized Gini index approach AI翻译
  作者：Gutjahr, Walter J.
  作者单位：University of Vienna
  摘要：The paper proposes an optimization model for the allocation of vaccines to a heterogeneous population composed of several subpopulations with different sizes and epidemiological disease transmission parameters. As the objective, an aggregated function combining a standard utilitarian efficiency criterion with a Gini index-related penalty term is considered. Contrary to previous work, we adopt an outcome equity view: The inequity measure is not based on vaccination fractions or other input fact...
• A boosting policy to optimize user forum performance: Model and validation AI翻译

  摘要：Near-constant Internet access through desktop or mobile devices has turned self-service support forums into the first port of call for users seeking to troubleshoot product or service issues. The firms providing these products and services also benefit from this trend since it reduces user support costs by diverting service requests away from costlier support channels, such as help desks. For the continued success of such a forum, however, the managing entity must ensure that users receive tim...
• It's not simply luck: The impact of network strategy, schedule padding, and operational improvements on domestic on-time performance in the US airline industry AI翻译

  摘要：Airlines showcase their on-time performance (OTP), a globally accepted operational performance metric, to demonstrate punctuality, service reliability, and attract air travelers. Airlines can adopt passive strategies, such as schedule padding, and active strategies, such as making operational changes/improvements, to improve their OTP. While there is a high degree of variation in airlines' OTP from year to year, it is unclear if and the extent to which airlines' active or passive actions impac...
• 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...
