We develop a logistics and transportation simulation that can be used to provide insights into potential outcomes of proposed military deployment plans. More specifically, we model the large-scale real-world military Deployment Planning Problem. It involves planning the movement of military units from their home bases to their final destinations using different transportation assets on a multimodal transportation network. We use an intelligent design of experiments approach to evaluate logistics factors with the greatest impact on the overall achievement of a typical real-world military deployment plan.
