This book constitutes the proceedings of the 16th International Conference on Application and Theory of Petri Nets, held in Torino, Italy in June 1995 The 26 revised refereed papers presented were selected from 73 submissions from 22 countries; in addition there are abstracts or full papers of the three invited talks. All theoretical and applicational aspects are addressed by the contributors coming from industry and academia. This volume representatively documents the progress achieved in this application-oriented area of research and development since the predecessor conference held one year earlier.

This book constitutes the refereed proceedings of the 25th International Conference on Applications and Theory of Petri Nets, ICATPN 2004, held in Bologna, Italy in June 2004. The 19 revised full regular papers and 5 revised tool presentation papers presented together with 6 invited papers were carefully reviewed and selected from 62 submissions. All current issues on research and development in the area of Petri nets are addressed, in particular concurrent systems design and analysis, modular systems development, formal specification, model validation, model checking, workflow management, flow charts, networking, formal methods in software engineering, etc.

This book constitutes the refereed proceedings of the 21st International Conference on Application and Theory of Petri Nets, ICATPN 2000, held in Aarhus, Denmark, in June 2000. The 20 revised full papers presented together with four invited surveys and four tool presentations were carefully reviewed and selected from 57 submissions. The papers address all current aspects of Petri net research and development including system design and verification, UML, compositionality, process algebras, model checking, computer networking, business process engineering, communication networks, etc. Various classes of Petri nets are discussed including safe Petri nets, high-level Petri nets, colored Petri nets, P/T nets, and timed Petri nets.

This book constitutes the refereed proceedings of the 20th International Conference on Application and Theory of Petri Nets, ICATPN'99, held in Williamsburg, Virginia, USA, in June 1999. The 21 revised full papers presented were carefully selected from 45 submissions. Also included are three invited presentations. The book presents state-of-the-art research results on all current aspects of Petri nets as well as advanced applications in a variety of areas.

This book constitutes the refereed proceedings of the 18th International Conference on the Application and Theory of Petri Nets, ICATPN'97, held in Toulouse, France, in June 1997. The 22 revised full papers presented in the volume were selected from a total of 61 submissions; also included are three invited contributions. All relevant topics in the area are addressed. Besides a variety of Petri net classes, workflow management, telecommunication networking, constraint satisfaction, program semantics, concurrency, and temporal logic are among the topics addressed.

The refereed proceedings of the 24th International Conference on Applications and Theory of Petri Nets, ICATPN 2003, held in Eindhoven, The Netherlands, in June 2003. The 25 revised full papers presented together with 6 invited contributions were carefully reviewed and selected from 77 submissions. All current issues on research and development in the area of Petri nets are addressed, in particular concurrent systems design and analysis, model checking, networking, business process modeling, formal methods in software engineering, agent systems, systems specification, systems validation, discrete event systems, protocols, and prototyping.

This volume contains the proceedings of the 22nd International Conference on Application and Theory of Petri Nets. The aim of the Petri net conferences is to create a forum for discussing progress in the application and theory of Petri nets. Typically, the conferences have 100{150 participants { one third of these coming from industry while the rest are from universities and research institutions. The conferences always take place in the last week of June. This year the conference was organized jointly with the 2nd International Conference on Application of Concurrency to System Design (ICACSD 2001). The two conferences shared the invited lectures and the social program. The conference and a number of other activities are co-ordinated by a steering committee with the following members: G. Balbo (Italy), J. Billington (Aust- lia), G. De Michelis (Italy), C. Girault (France), K. Jensen (Denmark), S. - magai (Japan), T. Murata (USA), C.A. Petri (Germany; honorary member), W. Reisig (Germany), G. Rozenberg (The Netherlands; chairman), and M. Silva (Spain). Other activities before and during the 2001 conference included tool dem- strations, a meeting on \XML Based Interchange Formats for Petri Nets", - tensive introductory tutorials, two advanced tutorials on \Probabilistic Methods in Concurrency" and \Model Checking", and two workshops on \Synthesis of Concurrent Systems" and \Concurrency in Dependable Computing". The tu- rial notes and workshop proceedings are not published in these proceedings, but copies are available from the organizers.

This book constitutes the refereed proceedings of the 31st International Conference on Applications and Theory of Petri Nets and Other Models of Concurrency, PETRI NETS 2010, held in Braga, Portugal, in June 2010. The 16 revised papers classified as theory papers (10), application papers (2), and tool papers (4) were carefully reviewed and selected from 50 submissions. All current issues on research and development in the area of Petri nets and related models of concurrent systems are addressed, novel tools as well as substantial enhancements to existing tools are presented.

This volume consists of the proceedings of the 29th International Conference on Applications and Theory of Petri Nets and Other Models of Concurrency (PETRI NETS 2008). The Petri Net conferences serve as annual meeting places to discuss the progress in the ?eld of Petri nets and related models of conc- rency. They provide a forum for researchers to present and discuss both app- cations and theoretical developments in this area. Novel tools and substantial enhancements to existing tools can also be presented. In addition, the conf- ences always welcome a range of invited talks that survey related domains, as well as satellite events such as tutorials and workshops. The 2008 conference had six invited speakers, two advanced tutorials, and four workshops. Detailed information about PETRI NETS 2008 and the related events can be found at http://ictt. xidian. edu. cn/atpn-acsd2008. The PETRI NETS 2008 conference was organized by the Institute of C- puting Theory andTechnologyat Xidian University,Xi'an, China, where it took place during June 23-27, 2008. We would like to express our deep thanks to the Organizing Committee, chaired by Zhenhua Duan, for the time and e?ort - vested in the conference and for all the help with local organization. We are also grateful for the ?nancial support of the National Natural Science Foundation of China (NSFC) (Grant No. 60433010), Xidian University, and the Institute of Computing Theory and Technology at Xidian University.
