• Flexible Data Aggregation for Prediction and Decision Making with Contextual Information: Applications in Retailing AI翻译
  作者：Peng, Zhenkang; Li, Chengzhang; Rong, Ying; Luo, Zichao; Ma, Guangrui; Zhao, Mingyong

  摘要：Problem definition: How should online retailers make demand predictions or operational decisions with limited relevant data? Motivated by conventional data aggregation approaches, we develop a flexible data aggregation (FlexDA) framework to adapt to different degrees of heterogeneity across products, thereby striking a better balance between the bias and variance of data-driven predictions and decisions. Methodology/ results: Under the FlexDA framework, we propose aggregating the individual da...
• The Nonlinear Impact of Promised Delivery Time on Online Purchasing AI翻译
  作者：Oblander, Shin; Jerath, Kinshuk
  作者单位：University of British Columbia; Columbia University
  摘要：Problem definition: For e-commerce companies to assess how best to invest in improving delivery times, it is important to understand how improving delivery times affects customer demand. In collaboration with a business-to-business (B2B) e-commerce company, we study how the promised delivery time in a quote affects the customer's purchase probability. Methodology/results: We use observational and experimental data from our partner with quote-level variation in promised delivery times. This all...
• Human-Centric Order Picking: Performance Prediction and Robot Assignment at a Robotic Fulfillment Center AI翻译

  摘要：Problem definition: E-commerce giants scale up their order-picking operations by adopting robotic fulfillment centers (RFCs). In RFCs, automated guided vehicles transport movable shelf racks to pickers' workstations, instead of having human pickers travel to pick items. Unfortunately, this apparent relief for pickers turns out to be a curse: Pickers become the bottleneck in the order-picking process. They undertake high-intensity, stationary, and repetitive tasks, which often cause both physic...
• 3D Printer Rentals: Technical Service Design and Pricing for Customers of Varying Expertise AI翻译
  作者：Zhang, Yue; Tomlin, Brian
  作者单位：Duke University; Dartmouth College
  摘要：Problem definition: Businesses with short-term production needs can rent equipment (e.g., 3D printer) from a manufacturer or distributor (hereafter, OEM) or use a manufacturing-services firm (e.g., print farm). Those who rent may vary in their expertise and therefore in their cost of attaining quality. Those who use a print farm benefit from the expertise of print-farm technicians. An OEM that offers rentals has an incentive to provide technical service to improve customer expertise so as to m...
• Analytics with Robust Epidemiological Compartmental Optimization Models AI翻译

  摘要：Problem definition: During pandemics, policymakers must make critical decisions about public health interventions and allocations of scarce resources in response to rapidly evolving diseases under high levels of uncertainty. Epidemiological models, such as the Susceptible-Exposed-Infectious-Recovered-type (SEIR-type) compartmental model, are indispensable tools for predicting how a pandemic may spread over time and how different public health interventions could affect the outcome. Based on su...
• Quality Signaling in Rewards-Based Crowdfunding: The Role of Deferred Payments AI翻译
  作者：Lyu, Jiancheng; Shen, Xiaobei; Zhou, Yuqian; Kong, Xiangyin
  作者单位：Chinese Academy of Sciences; University of Science & Technology of China, CAS; Zhejiang University
  摘要：Problem definition: The rise of crowdfunding hides a flaw: creators' private information that is unobservable enables them to exploit backers, stalling the sector. To shield backers, platforms now escrow part of raised funds as deferred-payment insurance. We explore whether the implementation of deferred payment (DePay) shapes quality signaling under private information and how to utilize DePay for better campaign outcomes. Methodology/results: We build a stylized signaling game with a represe...
• Robust Generator Maintenance Schedule for Frequency-Secure Power Systems AI翻译
  作者：Yang, Yang; Sun, Qiuzhuang; Peng, Jimmy Chih-Hsien; Tang, Loon Ching; Ye, Zhisheng
  作者单位：University of Macau; University of Macau; Singapore Management University; National University of Singapore; National University of Singapore
  摘要：Problem definition: Normal operations of a power system require that alternating current frequency be maintained at a nominal value, for example, 50 Hz, whereas severe deviation from this value due to power deficiencies can cause cascading generator trips. Maintaining the frequency requires adequate inertia and frequency regulation reserve, which are primarily provided by online generators. In daily operations, generators due for preventive maintenance must be taken offline, and thus an improp...
• Cancer Screening Outreach Guided by Machine Learning: The Benefits of Proactive Care AI翻译
  作者：Park, Minje; Chan, Carri W.; Boell, Keith; Mitchell, Elliot G.; Tariq, Abdul A.; Vawdrey, David K.
  作者单位：University of Hong Kong; Columbia University; University of Pennsylvania; Pennsylvania Medicine; Childrens Hospital of Philadelphia
  摘要：Problem definition: With the advance of data analytics, many disease prediction models have been developed with the intent of detecting diseases earlier and improving patient outcomes through earlier treatment. The operationalization of interventions and care based on these predictive models is critical to attaining these goals. We study the real-world effects of a machine learning-guided colorectal cancer screening outreach program deployed at a health system in Pennsylvania. Methodology/resu...

  摘要：Problem definition: Influencer marketing has become a prevalent strategy to promote products through social media. This paper examines the value of influencer marketing when followers not only learn from the influencer's signal but can also engage in social learning by observing peers' purchase behaviors and reviews. Methodology/results: We adopt an information design framework to analyze how a firm should value an influencer based on two key dimensions: the accuracy of the influencer's past r...
