Resource Modeling in Workflow Applications Michael zur Muehlen University of Muenster, Department of Information Systems Steinfurter Str. 107, D-48149 Muenster, Germany ismizu@wi.uni-muenster.de Abstract. Collaborative applications such as workflow management systems separate between a process model and an organizational model. While the process modeling capabilities of current workflow management systems are at a high level, the organizational meta models provided by these systems are very often at a very elementary level. Moreover, most systems fail to provide means to integrate non-human actors in workflow applications such as intelligent agents or technical resources, such as PPC systems or CNC machines. We provide a generic framework for the representation of resources that can be addressed by a workflow activity. In addition to a generic meta model we discuss dynamic issues that occur during the assignment process. A proposal for the realization of feedback evolution in order to enable organizational learning and security considerations conclude this paper.
