Abstract

This paper approaches the problem of analysing control strategies in the case of fire in a building. The elements of this problem present behaviours of different nature and therefore the use of a hybrid modelling formalism is necessary. Petri nets are used to model the discrete aspects and differential equation systems are used for the continuous ones. In order to realistically evaluate the safeness provided by the fire management system, faults, failures and other uncertainties, such as people behaviour, should be included in the model. Due to the model complexity, results are obtained using Monte Carlo simulation.
