Modeling of Service Systems

An important aspect in the field of service science is service modeling; however, no comprehensive modeling approach exists. In this regard, the authors analyze literature of service science and look at existing modeling approaches. Based on this analysis they identify concepts necessary for modeling services. This paper specifies a semi-formalized meta-model comprising the concepts found and for having a more applicable meta-model, the authors transfer it into a technical space. Additionally a concrete syntax and implemented an editor, which supports service modeling, is specified. Overall, this work comprises existing approaches and presents a well-structured formalized meta-model for the domain of service modeling. This meta-model may be used as a starting point for further research within the area of service modeling.
