Overcoming Heterogeneity in Business Process Modeling with Rule-Based Semantic Mappings

The paper tackles the problem of notational heterogeneity in business process modeling. Heterogeneity is overcome with an approach that induces semantic homogeneity independent of notation, driven by commonalities and recurring semantics in various control flow-oriented modeling languages, with the goal of enabling process simulation on a generic level. Thus, hybrid process models (for end-to-end or decomposed processes) having different parts or subprocesses modeled with different languages become simulate-able, making it possible to derive quantitative measures (lead time, costs, or resource capacity) across notational heterogeneity. The result also contributes to a better understanding of the process structure, as it helps with identifying interface problems and process execution requirements, and can support a multitude of areas that benefit from step by step process simulation (e.g. process-oriented requirement analysis, user interface design, generation of business-related test cases, compilation of handbooks and training material derived from processes). A use case is presented in the context of the ComVantage EU research project, where notational heterogeneity is induced by: (a) the specificity and hybrid character of a process-centric modeling method designed for the project application domain, and (b) the collaborative nature of the modeling effort, with different modelers working with different notations for different layers of abstraction in a shared on-line tool and model repository.
