Abstract
Process management has proven to be instrumental for the engineering and assessment of courses of actions for business operations in many industrial application domains. Processes management means appear therefore as natural vehicle for the definition and analysis of operating procedures also for the emergency management domain. The question arises of what is an appropriate modelling methodology and how tools tailored to the needs of emergency organisations can support this modelling methodology. This paper reports on the experiences gained in the course of modelling specific emergency processes, in our case the cross-organisational treatment of mass casualties. Then, we will introduce the tool platform of project ERMA that has been designed to support such processes.
