Simulation of wildland fire suppression is useful to evaluate deployment plans of firefighting resources and to experiment different fire suppression strategies and tactics. Previous work of fire suppression simulation uses analytical models based on a continuous space. This paper presents a design of fire suppression simulation using a discrete event agent model based on a discrete cellular space. We present a framework of wildland fire suppression simulation and describe how firefighting agents in direct attack, parallel attack, and indirect attack are modeled. Experiment results are provided to demonstrate the agent models and to compare them in different fire suppression scenarios.
