Abstract
The pyrolysis-related properties of the specimen are obtained by optimizing the repulsive particle swarm optimization technique. Eight pyrolysis-related properties were obtained: virgin thermal conductivity, char thermal conductivity, virgin specific heat, char specific heat, char density, heat of pyrolysis, pre-exponential factor, and activation energy. The surface temperature and the mass loss rate obtained using the optimized properties were consistent with the measured values. In assuming that the properties obtained are physically valid, and that the surface temperature and mass loss rate measured in the experiment are correct, a valid fire phenomenon may be considered for replication if fire analysis is conducted using the properties obtained from the procedures proposed in this study.
