Holonic and ambient control, using infotronic technologies

Les travaux présentés dans le cadre de cette thèse visent à explorer de nouvelles pistes d’amélioration de la flexibilité, de la sécurité et de la performance des systèmes de production en introduisant les technologies infotroniques dans leur système de pilotage. Cela s’inscrit dans la continuité des travaux sur le modèle PROSIS (Product, Resource, Order and Simulation Isoarchic System). La première piste concerne l’usage de la technologie RFID pour assurer l’intégrité du système d’information et de décision vis-à-vis de l’état matériel du système de production. Pour cela, un tag RFID est associé à la partie matérielle de chaque holon (M_holon), et permet d’assurer la synchronisation avec la partie informationnelle et décisionnelle associée (I_holon). La seconde piste gravite autour du concept d’intelligence ambiante. Les différents traitements de l’information à effectuer par les différents I_holons leurs sont proposés sous la forme de services disponibles en libre accès, en fonction de leurs besoins, par des unités informatiques de soutien. La dernière piste est relative à l’interconnexion entre les activités de production proprement dites et les fonctions support de transitique. Un système de transitique Montrac comprenant des navettes autonomes a été intégré au Holonic Manufacturing Execution System développé dans l’équipe, en utilisant les principes de PROSIS. Les démonstrateurs de ces 3 facettes d’un tel système de pilotage ont été implémentés et validés dans le cadre d'une plateforme de production. Cela a également permis de valider la performance de l’approche vis-à-vis de différents benchmarks issus de la littérature.The work done during this thesis aims to explore new ways to improve the manufacturing systems flexibility, safety and performances, introducing infotronic technologies into their control systems. This follows some previous work on the PROSIS (Product, Resource, Order and Simulation Isoarchic System) control model. The first way is about the use of RFID technology to ensure the integrity of the information and decision system, regarding the physical state of the manufacturing system. For that, a RFID tag is associated with the material part of each holon (M_holon), and this ensures the synchronisation wi the informational and decisional part (I_holon). The second way is the use of the ambiant intelligence concept. The I_holon has various information processing tasks to do during his lifetime. The tools to do these tasks are proposed to them in the form of services, freely available, and hosted by specialised support entities. The third way of improvement is related to the interconnexion of the actual product processing activities and the internal logistics functions. A Montrac transitic system, including autonomous shuttles, has been integrated in the Holonic Manufacturing Execution System developped during this thesis using the PROSIS principles. These ways of improvement has been implemented in demonstrators to validate their viability in a real small-size workshop. This has allows the comparison of the PROSIS approach with others, using the results of academic benchmarks

Architecture orientée services : pilotage d’atelier via intelligence ambiante

International audienceL'intelligence ambiante appliquée aux systèmes de production va profondément transformer les approches du pilotage de la production. Les technologies infotroniques vont élargir les capacités d'interagir, de réagir et de personnaliser les systèmes de pilotage avec des possibilités innovantes qui devraient déjà être envisagées et étudiées en profondeur. En effet, au-delà des applications d'identification, de traçabilité et de sécurité qui sont généralement considérés, ces technologies offrent la possibilité d'associer à chaque entité, constituant un système de production, une intelligence décisionnelle. Des propriétés d'autonomie sont ainsi associées à l'entité. Grace à ces avancées technologiques, le système de pilotage PROSIS (Product, Resource, Order, Simulation Isoarchic System), basé sur le paradigme holonique et une architecture isoarchique, est fondé sur une gamme de services ambiants fournis aux entités holoniques. Après avoir présenté le modèle PROSIS, nous abordons l’architecture orientée services, les services ambiants fournis sont décrits et la manière dont ces services peuvent être fournis est présentée

AHP/ANP a Decision Making Service in PROSIS Model

International audienceAn approach that relies on the use of the holonic paradigm, on an isoarchic architecture and on a decision-making capacity based on a multicriteria analysis is presented. The various concepts of this approach are addressed first. Then, the multicriteria decision methods based on AHP (Analytic Hierarchy Process) and its generalization ANP (Analytic Network Process) are detailed, as well as the implementation phases. The first obtained results on a case study are presented

Study of an intelligent and multicriteria scheduling service, using academic benchmarks

International audienceThe implementation of new production organization methods becomes essential in the evolution of companies context. These methods include scheduling. In this context, scheduling is generally multicriteria. To solve this problem we need multicriteria optimization methods to search all optimal solutions and multicriteria decision making methods to choose the best compromise between potential solutions. The objective here, is to evaluate the performance of a multicriteria decision making method used, in real time, in the holonic, isoarchic and multicriteria model (named PROSIS (Product, Resource, Order, Simulation, Isoarchic System)) through academic benchmarks. After presenting the existing intelligent control based on an intelligent scheduling service, the choice of the multicriteria aid method named 'Analytic Hierarchy Process' (AHP) is justified. After that, the implementation of the multicriteria scheduling service in PROSIS is described. At the end, the benchmarks allowing to study the performance of the multicriteria scheduling are presented before analysing the results

Service Oriented Architecture in PROSIS holonic control

May 25 - May 27International audienceAmbient intelligence applied to manufacturing systems will deeply transform approaches to production organization and control. Infotronics technologies will enlarge the capabilities to interact, to react and to customize control systems with innovative possibilities that should already be envisaged and thoroughly studied. Indeed, beyond identification, traceability and security applications that are generally considered, these technologies offer the possibility to associate to each entity, constituting a production system, a decisional intelligence. Autonomy properties are thus associated to the entity. Under these new advances, a control system based on the holonic paradigm and an isoarchic architecture, named PROSIS (Product, Resource, Order, Simulation Isoarchical System), was proposed. This approach provides a range of ambient services to the holonic entities. The aim of this paper is to present the service oriented architecture in the PROSIS control system. After presenting the holonic control system (PROSIS) model, the ambient services that can be provided are described and the way these services could be delivered are presented

RFID Synchronization for Ambient Services in PROSIS Holonic Control

International audienceProduct traceability is now an obligation in terms of observability and flexibility of manufacturing systems and logistics chains. RFID technologies are due to be more and more integrated into existing communication networks. New infotronic technologies will enlarge the capabilities to interact, to react and to customize control systems with innovative possibilities. New control approaches should be proposed based on the use of emerging technologies that would allow their operability in manufacturing sites. A model for ambient control production systems is proposed, based on a set of holonic entities interacting through set of entities that offer ambient services. After describing the PROSIS model, some of the ambient services that can be provided and the way these services could be provided are presented. Then, the impact of the proposed approach in terms of performance evaluation is studied
