Contribution à la reconfiguration des lignes de production : définition et démarche de choix de configurations alternatives.

Abstract : In this thesis we propose a formalism for defining RMS configurations, based on the modularity of the system, including both physical and logical aspects (so far considered separately in the literature), and performance (KPI) and model (flow simulation) aspects to align the proposal with the requirements of Industry 4.0 (the RAMI 4.0 architecture). The modular vision allows a precise description and analysis and leads to a better knowledge of the system to drive a reconfiguration. A reference data model emerges from this modular vision, and is used to generate the configuration database, which is the foundation of the proposed selection process for new configurations. This approach aims at capitalizing on past, present and potentially future configuration data of the system, in order to meet the needs of proactivity, data reuse and more generally of knowledge management in a reconfiguration process. A metric to evaluate the impact of a reconfiguration is proposed, in order to ensure a relevant configuration choice. An illustrative example and two industrial case studies have been conducted. They allow to validate the relevance of the proposed approach, and have also allowed to show that the approach is valid for mature systems as well as for systems still under design. The approach offers new perspectives for RMS controlled with holons. Nevertheless, the notion of aggregation (data, control logics, models) as well as the lack of automation of the selection process are some drawbacks of the proposal, but also represent promising topics for future works.
