3. Outlook

Current fire safety models are the subject of intense research. The introduction of various regulations on fire safety in the transport and building sectors is a driving force behind these developments. In the years to come, two avenues seem to be taking shape:

• on the one hand, the field models receive increasingly sophisticated sub-models to deal with various aspects, in particular radiation and the link between solid pyrolysis and the gas phase;

• on the other hand, increased computing capacity means that problems can be approached in a probabilistic way. The use of zone models, which are less sophisticated but faster, is thus becoming increasingly common in probabilistic studies, and this trend may be followed by more complex models in the future.
