Weakly Coupled Dynamic Programs, Fluid Limits, and COVID-19: How Optimization Can Help Inform Policymaking

Huikang Liu and Wolfram Wiesemann summarize recent work developing a model-based national patient prioritization scheme in response to the limited capacity in the UK due to the continued COVID-19 pandemic. Their approach leverages dynamic programming to simultaneously estimate capacity and account for the dynamics of patient states and available resources.
