Changeable factory systems are a viable strategy for manufacturing companies to cope with dynamic and uncertain environments, characterized by frequent engineering changes, product and technology innovations, and continuous improvement initiatives often resulting in changes of factory systems. Flexibility and changeability are considered beneficial properties helping to be prepared for the various possibilities of an uncertain future. To support the analysis of these system properties, suitable modelling techniques are required covering both structural and element properties. Hence, the objective of this paper is to provide a graph-based domain specific modelling approach for factory systems. Metamodels for nodes and edges are suggested based on metamodel and ontology design theory and an extensive review of factory planning literature. The approach is demonstrated by modelling a simple compressor shaft workshop production. Finally, promising application perspectives of the graph-based modelling approach are outlined.
