UN ENVIRONNEMENT G-DEVS/HLA :
APPLICATION A LA MODELISATION ET SIMULATION DISTRIBUEE DE WORKFLOW

Abstract : The researches of this thesis are divided in:
− the proposition of conservative distributed simulation algorithms of models DEVS / G-DEVS,
− the definition and the realization of a G-DEVS modeling and simulation (M&S) environment HLA compliant implementing the proposed algorithms,
− the application of the environment in the M&S of Workflow.
First, we introduced a G-DEVS distributed root coordinator component, including an algorithm of commu-nication with the RTI HLA based on the mechanism of conservative synchronization and using positive Looka-head. Then, we proposed two original algorithms for the computation of Lookahead concerning the current state of a G-DEVS model. These algorithms, based on the analysis of the variation domain of the “lifetime” function of the model, increase the performances of the distributed simulation as the led experiments illustrate it.
Based on these approaches, we developed a distributed G-DEVS / HLA M&S environment. This environ-ment was integrated into an application of Workflow. The possibilities offered by the environment were illus-trated by the study of company's real cases of Workflow.
