  摘要：During emergencies humanitarian supply chains need to respond swiftly, very often without time for good planning that may end up in excessive waste and emissions. This short-term focus on saving people's lives during disaster responses may harm communities and the planet in the long-run. Even long-term (development) focus on improving the life conditions of the poor may be either unsustainable due to the lack of community involvement or inequitable due to lack of resources. At the same time, c...
• Improving Funding Operations of Equity-based Crowdfunding Platforms AI翻译

  摘要：Equity-based crowdfunding platforms enable investors to come together to invest in startups and help lay-investors to follow the lead of investors with good startup evaluation skills. Crowdfunding platforms often gather users' inputs to evaluate investors and startups, but such inputs are quite noisy and often rely on past performance. Many investors with good evaluation skills do not have substantial past investment experience but still can lead investment rounds. This helps provide investmen...

  摘要：Technologies that enable e-visits-remote interactions between patients and physicians-are touted as a way to improve and expand primary care. We study a setting in which a physician can divert some of the patient demand away from the office visits and into the e-visits, which utilize less of the physician's service capacity while maintaining an appropriate quality of care. We explicitly model a distinguishing feature of primary care settings: patient office revisit intervals are determined joi...
• Differentiating Interhospital Transfer Types: Varied Impacts and Diverging Coordination Strategies AI翻译

  摘要：Interhospital transfer (IHT) is common in care delivery. As a form of care transition, IHT faces coordination challenges and can negatively affect care outcomes. Understanding the underlying reasons and the associated operational challenges of different IHT types can help hospital managers design mitigation mechanisms to improve the IHT care outcomes. We conceptually and empirically differentiate between clinical and non-clinical transfers based on their unique characteristics and compare thei...

  摘要：Meeting the United Nations Sustainable Development Goals (SDGs) will require adapting or redirecting a variety of very complex global and local human systems. It is essential that development scholars and practitioners have tools to understand the dynamics of these systems and the key drivers of their behavior, such as barriers to progress and leverage points for driving sustainable change. System dynamics tools are well suited to address this challenge, but they must first be adapted for the ...
• Women are an Advantage in Supply Chain Collaboration and Efficiency AI翻译

  摘要：A large body of literature has documented gender differences in prosocial behaviors, but little is known about the implications of different gender pairings of partner firm agents for supply chain performance. Using a production decision experiment which features asymmetric information and asymmetric risk sharing, we report three key findings. First, women are more collaborative than men in the role of both buying agents and supply agents. Second, information about counterparts' gender affects...
• Mitigating Product Shortage Due to Disruptions in Multi-Stage Supply Chains AI翻译

  摘要：We focus on the optimal use of risk mitigation inventory (RMI) and reserve capacity to manage disruption risk in serial multi-stage supply chains where product transformation occurs at each stage. We find that under reasonable conditions it is better to hold more RMI downstream than upstream even when the upstream holding costs are lower. We also find that it is often optimal to hold more reserve capacity downstream than upstream. While in one-stage supply chains RMI and reserve capacity alway...
• Constrained Assortment Optimization Problem under the Multilevel Nested Logit Model AI翻译

  摘要：We study the choice-based constrained assortment optimization problem under the multilevel nested logit model with a no-purchase option in every choice stage. For this problem, each candidate product is associated with a fixed profit. The goal is to identify the optimal assortment satisfying a cardinality constraint to maximize the expected profit per customer. There is a cardinality limitation imposed on nodes in the second lowest level. A polynomial-time algorithm with computational complexi...
• Optimal Bayesian Demand Learning over Short Horizons AI翻译
  作者：Wang, Jue
  作者单位：Queens University - Canada
  摘要：We investigate the optimal Bayesian dynamic pricing and demand learning policy over short selling horizons, where the pricing decisions are time-sensitive. The seller fine-tunes the price near an incumbent price in order to maximize the total revenue. The existing literature focuses on policies that are asymptotically optimal, that is, near optimal when the selling horizons are sufficiently long, but little is known about the optimal Bayesian policies, especially over short horizons. We formul...
• Printing Spare Parts at Remote Locations: Fulfilling the Promise of Additive Manufacturing AI翻译

  摘要：We investigate the benefits of on-site printing at remote geographic locations, where access to spare parts is intermittent and supplies are replenished at fixed intervals. Organizations typically have no solution to spare parts shortages other than expensive expediting orders, or waiting for a part to arrive with the next replenishment. We investigate whether on-site three-dimensional (3D) printing of spare parts can bring relief. Our work extends dual-sourcing literature with fixed order cyc...
