  摘要：Fuel is an essential commodity in society with an amplified role during disasters. Disasters often cause a spike in demand for fuel and impose physical and operational constraints on fuel distribution. Accordingly, public and private sector stakeholders seek disaster preparedness and response interventions to ensure an adequate supply of fuel for emergency activities. We develop models to quantify downstream operational flow capacity, i.e., the volume of fuel that can be distributed from bulk ...
• Business Model Innovation for Ambulance Systems in Low- and Middle-Income Countries: Coordination and Competition AI翻译

  摘要：Several low- and middle-income countries' emergency transportation systems (ETSs) do not have a centralized emergency number. Instead, they have many independent ambulance providers, each with a small number of ambulances. As a result, ETSs in these contexts lack coordination and ambulances. Using a free-entry equilibrium model, we show that in such decentralized systems, the probability that any given call can be served by at least one ambulance, that is, its coverage, is at most 71.54%, rega...

  摘要：Live-streaming e-commerce has gained tremendous success as a new form of business model over the past few years. Nevertheless, there has been scarce research examining the effect of exogenous stimulus-driven factors (i.e., social cues such as promotion coupons) on the profit of the live-streaming platform. We model the continuous evolvement of the aggregate viewer involvement level with geometric Brownian motion and investigate the optimal timing and depth of promotion insertion policy. Our fi...
• How much do customer ordering practices drive medical supplies distribution (in)efficiency for primary care markets? AI翻译

  摘要：Companies across many industries seek to understand how customer ordering impacts supply chain distribution performance. In the US medical supplies industry, wholesalers are uniquely positioned to use information about downstream customers to study and potentially influence buyer policies and practices due to their industry scale and data visibility. In this study, wholesale medical supplies buyers are first examined based on their ordering practices over a 2-year window using the theoretical ...
• Multiperiod channel coordination in franchise networks: The necessity of internal inventory trading and franchiser involvement AI翻译

  摘要：Facing consumers' growing demand for fast order fulfillment, it is important yet challenging for franchise companies to best incentivize frequent inventory sharing among their independent franchise retailers or dealers to achieve channel coordination. Past literature has only addressed such channel coordination for one-time inventory sharing using contractual agreements, which unfortunately do not work for frequent inventory sharing. In this study, we consider multiple inventory-sharing opport...
• Optimal inventory control with cyclic fixed order costs AI翻译
  作者：Taube, Florian; Minner, Stefan

  摘要：We consider a periodic review single-item inventory model under stochastic demand. Every m periods, in the regular order period, fixed order costs are K. In the periods in-between, the intraperiods, higher fixed order costs of L>K$L>K$ apply. The literature on optimal inventory policies under fixed order costs does not account for these time-dependent fixed order costs. By generalizing existing proofs for optimal inventory policies, we close this gap in inventory theory. The optimal inventory ...
• Bridging the gap: Applying analytics to address gender pay inequity AI翻译

  摘要：Employers are under increasing pressure from regulators, investors, and their own employees to address gender pay inequity in their compensation structure. However, managers tasked with measuring and closing gender and other pay gaps have few helpful quantitative tools at their disposal. We design and implement an algorithm that measures whether an employer has a pay gap and suggests salary adjustments to close it, all while supporting the employer's goals with respect to equity, culture, and ...
• The role of volunteer experience on performance on online volunteering platforms AI翻译

  摘要：Online volunteering platforms allow humanitarian organizations (HOs) to recruit volunteers to work remotely on projects of varying urgency. While removing time and space constraints enables HOs to scale up their volunteer force, HOs must manage greater heterogeneity in volunteers' experience. We investigate empirically how volunteers' experience impacts two performance metrics on online volunteering platforms: project completion rate and volunteer retention. In addition, we examine the conditi...
• Partially partitioned templating strategies for outpatient specialty practices AI翻译
  作者：Bai, Miao; Berg, Bjorn; Sir, Esra Sisikoglu; Sir, Mustafa Y.
  作者单位：University of Connecticut; University of Minnesota System; University of Minnesota Twin Cities
  摘要：Templating strategies specify policies on capacity allocation and appointment booking, which are central to patient access management in outpatient specialty practices (SPs). In the widely implemented partitioned templating strategy, appointment capacity is allocated exclusively to each patient group defined by a combination of patient attributes and medical conditions, which often results in utilization challenges for SPs. Motivated by problems faced by an SP within a large academic medical c...
• Impact of pandemics on humanitarian retailing operations: A voucher's case AI翻译

  摘要：In 2020, the world started a fight against a pandemic that has severely disrupted commercial and humanitarian supply chains. Humanitarian organizations (HOs), like the World Food Programme (WFP), adjusted their programs in order to manage this pandemic. One such program is cash and voucher assistance (CVA), which is used to bolster beneficiaries' freedom of choice regarding their consumption. In this vein, WFP supports local retailers to provide CVA to beneficiaries who do not have access to a...
