报告摘要:Historically, research in decision making under uncertainty in operations research (OR) has focused on models and their optimization. In an ideal setting, optimization was substantiated by estimating the model parameters, such as distributions, based on actual data. Machine learning (ML) has been developed to predict the quantity of interest (predictive analytics). However, ML does not generally address optimal decision-making under uncertainty that is appropriate for OR problems (prescriptive analytics). In recent years, a new approach emerges, i.e., combining ideas from ML and OR in developing a framework for using data to prescribe optimal decisions in OR problems.  In this talk, we first give a review on this development and then show an on-going research project in a healthcare management application.  In the project, we intend (1) to develop a ML predictive model to early identify high-risk subpopulation for further follow-up interventions, and (2) to use the predictive model to guide allocation of limited health care resources to balance efficiency - readmission reduction and health outcomes of patients.
