Within the framework of HAZARD I, fire egress analysis
is performed using the EXITT program. Yet another way
to analyze fire egress employs newly developed multiple
objective dynamic programming. This paper compares
these two approaches by applying them to a model fire of
moderate power in a residential building. The findings
demonstrate that multiple objective dynamic programming
can compute all the paths EXITT finds, but EXITT can't
find all the paths multiple objective programming can.
Some trade-offs inherent in choosing among the computed
egress paths are discussed, and the features of the two
fire egress methods are contrasted.
