An extension of the graph-grammar based simulator GroIMP for visual specification of plant models using components

The FSPM platform GroIMP was extended by a graphical editor for components of rule-based models, enabling a better re-use and comparison of submodels. Components can be arbitrarily nested and can have several types of connectors with different semantics. The new tool provides a parallel main­tenance of model code and of the graphical view showing the component structure.
