Titre anglais : Formal specification and design of distributed systems
Abstract : To design Distributed Systems (DS), the advantages of integration of Petri Nets (PN) and Object Oriented (OO) concepts had been widely discussed in the literature. Some integrations are mainly concerned with providing a formal basis for object oriented languages. Others focus on combining the abstract data type of the object technology with Petri nets. In both approaches the use of Petri nets is explicit so the resulting model diverge from the classical OO technology. The aim of this work is to bridge the gap between the two paradigms by a formal transformation from a 'pure' OO model derived from the Reference Model for Open Distributed Processing to a Petri net modular model. So specification, design and validation of Distributed Systems can be considered in the OO paradigm which is most appropriate while verification is done in the PN paradigm for better formality. The OO model we use is dedicated to design of distributed systems and support validation of the result in the earliest. The transformation into a PN model allows to undertake formal verification and simulation of the design.
Key-words : Distributed Systems, Specification, Design, RM-ODP, Validation, Formal Verification, Simulation, Petri Nets.
