Abstract

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.
