Modeling individual self-protective behavior during epidemics
Fig 3
Decision trees for individual agents.
Individual agents make decisions through three decision trees. An agent’s compliance with NPIs, such as wearing a mask or maintaining social distancing, is determined through decision trees (A1) and (A2), depending on its vaccination status. If an agent is eligible for vaccination, it decides on its willingness to get vaccinated using the decision tree (B). Only two probability values (highlighted) are based on an agent’s perception that changes over time: and
, while other probability values are fixed at a certain value for simplification. This is to minimize the complexity of the model and have only one dynamic opinion value closely related to each of the two self-protection behaviors: NPI compliance and vaccination willingness.
