A stochastic model for human behaviour
The model has input from other CESARE-Risk models, in particular the system model and the smoke and fire growth models.
Occupant response in a fire emergency can be depicted as involving three stages (recognition, action or coping behaviour, and evacuation). These stages are a convenient summary of many actions, the most diverse being in the coping stage, and they are not universally applicable. In order to cope with the operational demands of a time-based risk model, the time when evacuation starts is used to separate the first two stages (initial recognition and coping behaviour) from the third stage (evacuation movement), leading to the distinction between the response model and the evacuation model.
