Exploiting User-definable Synchronizations in Graph Transformation

Parametric Synchronized Hyperedge Replacement (PSHR) is a graph transformation formalism where productions specifying the behavior of single components can be synchronized to give full transitions. The main feature of PSHR is that the synchronization model is user-definable. To enhance the applicability of the approach we propose a simplified and more suggestive semantics, preserving however the expressive power of the original one. We also show how some common synchronization models can be formalized and exploited inside PSHR. This allows to simplify the modelling step, and the produced model too. We apply this approach to the airport case study of FET-GC project AGILE.
