Workshop on Applications of Region Theory (ART 2013)
Website of ART 2013
Regions have been defined about 20 years ago by A. Ehrenfeucht and G. Rozenberg as sets of nodes of a finite transition system that correspond to potential conditions that enable or disable transition occurrences in a corresponding elementary net system. Thus, regions have been the essential concept for synthesis of an elementary net systems from its “anonymous” state graph (states are unknown but transitions between states are known). Since that time, many generalizations and variants of the synthesis problem of Petri nets from behavioral descriptions have been studied, including synthesis of more general Petri net classes, synthesis from languages, synthesis from partially ordered runs and synthesis from incomplete behavioral descriptions. All this work has in common that the transition names are given more or less directly by the behavioral description. The places of the net to be synthesized always correspond to regions which are defined in many different ways, depending on the form of the behavioral description. A main issue in this research is the study of regions, whence we call the entire research direction region theory. The aim of this workshop is to bring together people working in these or other application areas of region theory, to exchange ideas and concepts and to work on common workshop results.
