MANUFACTURING AND PETRI NETS

A Workshop within the
XVIII International Conference on
Applications and Theory of Petri Nets
Toulouse, June 23, 1997

Workshop description

Petri nets have been applied in manufacturing for many years. Manufacturing systems, where many processes evolve concurrently and share common resources, are indeed complex. Thus formal modeling, analysis and synthesis techniques are important issues for their design and operation. In recent years, as flexible manufacturing systems are increasingly used in practice, Petri nets are commonly used for performance evaluation and real-time control (directly or under the form of the Grafcet which is an international standard for Programmable Logic Controllers).

This directory contains the proceedings of the ``Second International Workshop on Manufacturing and Petri nets'' (Toulouse June 23, 1997). It is indeed the second workshop on this subject within the ``International Conferences on Application and Theory of Petri Nets'' after that of the Osaka conference last year.

We have received 13 submissions and 9 have been accepted for presentation after evaluation of two or three referees. In addition, two invited papers are given, one is a survey on distributed simulation for discrete event systems, and the other one is about logic and fuzzy Petri nets. The topics of the other papers range from scheduling and production planning to verification and fault tolerance.

We would like to express our gratitude to all authors of submitted papers and the referees. For the local organization of the Workshop all of us are thankful to Pierre Azema and his colleagues.
