Abstract: In the event of a disaster in Germany a so-called executive staff is set up. In support of their work they refer to emergency plans, which describe the chronological order of a set of suitable measures for a dedicated event e.g. an evacuation. These plans only exist in the form of large printed documents. Hence, the technical support for executing emergency plans is very limited. In this paper we present a model for a workflow management system (WfMS) for supporting the modeling, execution and management of emergency plans before and during a disaster. It is based on the idea that emergency plans are similar to business processes and can therefore be modeled as workflows. In contrast to most traditional WfMS, the introduced approach supports unstructured activities and their delegation as well as the management of resources. Furthermore, we analyze drawbacks of the current process for disaster management using emergency plans.
