Net rewriting system for GSPN a RMS case study

The use of Petri Nets in the design of Reconfigurable Manufacturing Systems is an attractive field. Petri Nets allow modelling in an abstract way RMSs and to make specification, refinement, verification and validation of these systems. Moreover, the use of Stochastic Petri Nets allows the designer to catch more indispensable aspects (time and stochastic events) of RMSs, thus the designer can make performance evaluation. In order to study the reconfigurability, explicitly, in Petri nets, several works proposed extension for PN called reconfigurable Petri nets. However, these extensions do not deal yet with stochastic Petri nets. The objective of this paper is to present an extension of Stochastic Petri nets to deal with reconfigurability.
