  摘要：Training is an important business in the service sector. Usually, a training program involves multiple sessions and each session contains multiple activities. Although it is essential for customers to participate in all training sessions and activities, many customers fail to complete the program because the training experience is too stressful. Given the importance of customer retention in the training programs, we investigate the modeling and optimization of the retention-oriented training p...
• Last-Mile Attended Home Healthcare Delivery: A Robust Strategy to Mitigate Cascading Delays and Ensure Punctual Services AI翻译

  摘要：The attended home healthcare (AHH) industry is experiencing rapid growth due to the rising demand from an aging population and the potential benefits of alleviating pressures on traditional healthcare resources. However, ensuring timely one-on-one AHH services for homebound patients remains a challenge because of cascading delays arising from uncertainties in travel and service times. To address this issue in last-mile homecare delivery, we develop a systematic cascading delay mitigation strat...
• Transaction Fee Mechanisms and User Welfare in Permissionless Blockchains AI翻译

  摘要：A transaction fee is fundamental in maintaining the stability and decentralization of a permissionless blockchain, the infrastructure underlying major cryptocurrency networks such as Ethereum and Bitcoin. This fee, set and paid by users when initiating each transaction, aggregates to over $24 million daily on Ethereum, imposing a nontrivial barrier to wider adoption. What is worse is that it is disproportionately borne by small users. Like Bitcoin, Ethereum started with a name-your-own-price s...
• The Interplay of Organizational Structure and Strategic Inventory Under Supply Chain Competition AI翻译

  摘要：In this study, we investigate the impact of organizational structures on supply chain participants, specifically when retailers establish strategic inventory in a competitive environment. We build a two-period supply chain model in which two retailers procure from a common supplier, compete in multiple markets, and can carry inventory from the first period to the second. We characterize the optimal strategies for firms under three scenarios, depending on whether each retailer operates under ce...
• MT-GPD: A Multimodal Deep Transfer Learning Model Enhanced by Auxiliary Mechanisms for Cross-Domain Online Fake News Detection AI翻译

  摘要：The proliferation of fake news, more recently multimodal fake news, poses a significant threat to individuals, organizations, and society. While online social media platforms have employed automated methods to combat fake news, they face two notable challenges: the scarcity of labeled data and the diversity of news domains. To enhance the effectiveness and efficiency of online platforms in mitigating the spread of fake news, this study proposes MT-GPD (multimodal deep transfer learning with ga...
• Flexible Revenue-Sharing Contract in a Digital-Content Supply Chain Under Heterogeneous Beliefs of the Parties AI翻译
  作者：Avinadav, Tal; Chernonog, Tatyana; Khmelnitsky, Eugene
  作者单位：Bar Ilan University; Tel Aviv University
  摘要：We study the design of a novel, flexible revenue-sharing contract between a platform and an app developer (or other digital content provider) when the parties hold heterogeneous beliefs with regard to the future income. The current contracts adopted by platforms in reality invoke a policy of two or three commission levels based on historical revenue data. We design a contract in which the commission is a continuous function of the revenue generated by the app or other digital content within th...
• Procurement for Empowerment: The Impact of Female Decision-Makers in Reproductive Health Supply Chains AI翻译
  作者：Karimi, Amir; Roy, Dwaipayan

  摘要：Access to contraceptives empowers women to not only exercise their reproductive rights and avert unintended pregnancies, but also to prevent a spectrum of adverse societal and health outcomes (e.g., unfulfilled career aspirations, unsafe abortions, maternal deaths.) However, in low- and middle-income countries (LMICs), where resources are limited and women are under-represented as decision-makers in national governments, reproductive health has not traditionally been prioritized. Motivated by ...
• Rationing scarce healthcare capacity: A study of the ventilator allocation guidelines during the COVID-19 pandemic AI翻译

  摘要：In the United States, even though national guidelines for allocating scarce healthcare resources are lacking, 26 states have specific ventilator allocation guidelines to be invoked in case of a shortage. While several states developed their guidelines in response to the recent COVID-19 pandemic, New York State developed these guidelines in 2015 as pandemic influenza is a foreseeable threat, one that we cannot ignore. The primary objective of this study is to assess the existing procedures and ...
• Incentives for Information Revelation in a Supply Chain and the Bullwhip Effect AI翻译

  摘要：Getting downstream firms in a supply chain to share private information about consumer demand with their suppliers is generally considered a prerequisite to dampening the bullwhip effect, that is, the amplification of demand shocks as they pass upstream in a supply chain. If downstream firms are reluctant to share their demand information, how can they best be incentivized to do so, and what does the optimal incentive scheme imply for the bullwhip effect and supply chain efficiency? We examine...
• Spatial-Data-Driven Facility Location Planning AI翻译

  摘要：The placement of facilities in service regions with continuously distributed demand poses a difficult problem, often requiring discretization methods that can potentially introduce approximation errors. This study presents a robust approach to address this challenge of continuous spatial distribution by considering the problem of facility placement under the spatial uncertainty associated with future demand locations, without resorting to discretization and its associated errors. We propose a ...
