Solving the Problem of Multiple-Criteria Building Design Decisions with respect to the Fire Safety of Occupants: An Approach Based on Probabilistic Modelling

Table 3

Probability distributions of the random variables used for the computer fire simulation in the hospital building considered in a MCDM problem.

Variable	Symbol	Mean	Coeff. of var.	Distribution
The fluctuation of the oil fire HRR around the mean value (Figure 10)		605 kW	0.05	Normal
The random duration of oil fire (Figure 10)		433 s	0.07	Normal
The fluctuation of the flue fire HRR around the mean value at (Figure 11)		0 kW	0.07	Lognormal
The fluctuation of the cupboard fire HRR around the mean value at (Figure 12)		0 kW	0.05	Lognormal
The temperature of wind glass breaking		250°C	0.05	Normal
The fraction of the broken glass area		0.222	0.354	Beta

HRR: heat release rate.
The variables and () are assumed to be correlated with the correlation coefficients calculated by (10).
Beta distribution with the parameters 6 and 21 and the mode of 0.2.
