HIERARCHICAL SYSTEM DESIGN USING REFINABLE RECURSIVE PETRI NET

摘要

This paper is in the framework of the specification and verification of concurrent dynamic systems. For this purpose we propose the model of Refinable Recursive Petri Nets (RRPN) under a maximality semantics. In this model a notion of undefined transitions is considered. The underlying semantics model is the Maximality Abstract Labeled Transition System (AMLTS). Then, the model supports a definition of a hierarchical design methodology. The example of a cutting flame machine is used for illustrating the approach.
