A discussion of object-oriented process modeling approaches for discrete manufacturing on the example of the semiconductor industry

We introduce a domain specific object-oriented data model for the high-tech discrete manufacturing on the example of the semiconductor company Infineon Technologies AG. This model is needed to describe the complex supply chain of a global company in the competitive semiconductor arena with frequent product changes. However, the data model alone is not solving all problems. For this we need e.g. event-driven internet-based workflows. To get those in a structured way, we show possibilities to come from an object-oriented data model to object-oriented business processes based on existing process models. Two ways - one with SysML and one with ARIS - are shown conceptually and are discussed. An outlook is given on how this approach will provide internet-based workflows on the one hand, and it also shows up process improvement potentials on the other hand.
