An optimal control policy for COVID-19 pandemic until a vaccine deployment

When an outbreak starts spreading, policy makers have to make decisions that affects health of their citizens and the economic. Some might induce harsh measures, such as lockdown. Following a long harsh lockdown, economical declines force policy makers to rethink reopening. But what is the most effective reopening strategy? In order to provide an effective strategy, here we propose a control strategy model. Our model assesses the trade-off between social performance and limited medical resources by determining individuals9 propensities. The proposed strategy also helps decision makers to find optimal lockdown and exit strategy for each region. Moreover, the financial loss is minimized. In addition, a study of a COVID-19 dataset for Los Angeles County is performed to validate our model and its results.
