Comparison of simple graphical process models

Comparing structure of graphical process models can reveal different variations of processes. Since most contemporary norms for process modeling lean on directed connectivity of objects in the model, their connections structure form sequences which can be translated into performing scenarios. While the sequences can be tested for completeness in performing process activities using simulation methods, the similarity or difference of static characteristics of sequences in different model variants is difficult to explore. The goal of the paper is to test the appliance of a method for comparison of graphical models by analyzing and comparing the static characteristics of process models. Therefore a metamodel of process models is developed and a comparison procedure conducted using a graphical model comparison algorithm
