N2 - A risk analysis tool called Probabilistic Fire Simulator
(PFS) is developed for the computation of the
distributions of fire model output variables and the
sensitivities of the output variables to the inputs. In
this work, a new technique is developed for the use of
two different fire models in the same Monte Carlo
simulation. The Two-Model Monte Carlo technique provides
a computationally effective means to improve the accuracy
of the fast but inaccurate models, using the results of
the more accurate but computationally more demanding
models. The technique is tested in two scenarios:
calculation of a ceiling jet temperature and a simulation
of a simple room fire, and finally applied on NPP relay
room fire.
