Metamodel Uncertainty

In risk-related research of fire safety engineering, metamodels are often applied to approximate the results of complex fire and evacuation simulations. This approximation may cause epistemic uncertainties, and the inherent uncertainties of evacuation simulations may lead to aleatory uncertainties. However, neither the epistemic ‘metamodel uncertainty’ nor the aleatory ‘inherent uncertainty’ have been included in the results of the metamodels for fire safety engineering. For this reason, this paper presents a metamodel that includes metamodel uncertainty and inherent uncertainty in the results of a risk analysis. This metamodel is based on moving least squares; the metamodel uncertainty is derived from the prediction interval. The inherent uncertainty is modelled with an original approach, directly using all replications of evacuation scenarios without the assumption of a specific probability distribution. This generic metamodel was applied on a case study risk analysis of a road tunnel and showed high accuracy. It was found that metamodel uncertainty and inherent uncertainty have clear effects on the results of the risk analysis, which makes their consideration important.

According to the chemical industrial parks current development trend in China, the fire risks, fire safety situations and the existing problems of petrochemical parks have been widely surveyed. And the main basic contents of chemical industrial parks fire safety planning are described in the paper. Through the researches on fire safety planning of chemical industry park and its evaluation system, based on the security planning of the chemical park, the fire safety planning methods and planning procedure to improve the petrochemical industrial park fire prevention levels are proposed on the basis of fire risk analysis.
