The underlying equations used in the fire models HAZARDI
and CONRAD2 are examined to establish a prototype method
for sensitivity analysis applied to currently available
zone fire models. Generic differential equations are
derived which can supplement existing equations in fire
models to estimate the time-varying sensitivity of model
outputs. The implications on the validity of the
solutions obtained and on the computing resources
necessary to obtain such sensitivity information is
discussed. The results of the proposed analytical
approach is compared with estimates from finite
difference analyses for the CONRAD2 model. These finite
difference methods, while more computing intensive,
provide more believable results than the analytical
