Preface
This booklet contains the proceedings of the Workshop on Software Engineering and Petri Nets (SEPN), held on June 26, 2000. This workshop was held in conjunction with the 21st International Conference on Application and Theory of Petri Nets (ICATPN-2000), organised by the CPN group of the Department of Computer Science, University of Aarhus, Denmark. The SEPN workshop papers are also available in electronic form via the web page: www.daimi.au.dk/pn2000/proceedings
The aim of the workshop was to bring together researchers and practitioners with inter- ests in Petri nets and/or software engineering, with the goal of exploring more closely the potential impacts and pitfalls in applying net-based formalisms to software development problems.
All submitted papers were refereed and evaluated under the direction of a program com- mittee with the following members:
Jonathan Billington, University of South Australia (Australia) Ugo Buy, University of Illinois at Chicago (USA)
Robert France, Colorado State University (USA) Dino Mandrioli, Politecnico di Milano (Italy) Mauro Pezze, Politecnico di Milano (Italy)
Sol Shatz, University of Illinois at Chicago (USA)
The program for the workshop included ten selected papers and two invited talks. The invited speakers were: Professor Michal Young (Oregon State University, USA) and Pro- fessor Manfred Broy (Technishe Universitat Munchen, Germany).

Co-organizers, SEPN-2000
