More and more often civil and military threats tend to occur within urban environments which raise the demand for increasing the knowledge and understanding of these events and their effects on society. Crisis simulation modeling could provide excellent support for this demand, and we present a generic platform for modeling and simulation of crises in urban environments, SimCUE, that is proposed by FOI. Such a tool could be used for planning of operations and in preparation for training rescue personnel and decision makers in emergency response. Initially our own existing models will be used as a basis for the platform but we intend and need to extend those with more models describing different kinds of disasters. An overview of existing research models and efforts is presented as well as some examples of plausible scenarios where the tool can be used.
