This paper presents a comparison between two standby redundancy implementations within the context of a holonic controller for a manufacturing cell: using the Erlang/OTP programming framework and the JADE (Java Agent DEvelopment framework) multi-agent system (MAS) framework. Erlang (and its associated library OTP) contains several features that greatly simplify the implementation of standby redundancy. JADE is a popular MAS framework that has become the prevailing solution within academic research in holonic control. Both solutions implement standby redundancy using standard features of their respective frameworks. A case study comparison is performed using both quantitative and qualitative measures. The comparison shows that, for the case study, the Erlang/OTP implementation performs better than the JADE implementation for all the standby-redundant metrics: it achieves shorter changeover times, lower computational requirements overall, less computational and state synchronisation overhead, and greater fault handling flexibility. However, Erlang/OTP lacks the level of supporting communication and protocol infrastructure that is available in JADE due to JADE’s strong heritage within multi-agent systems.

Today, manufacturers are seeking new approaches that allow designers to effectively adapt manufacturing systems to an uncertain and disruptive environment. The concept of the reconfiguration of manufacturing systems is proposed in order to find solutions to the occurrence of disturbances within a complex manufacturing system. In the literature, integrating reconfiguration early in the design phase into system engineering by following an approach based on standards and paradigms is beginning to call for several new research studies. We propose a new approach based on system engineering to design manufacturing production systems so that they are reconfigurable from the point of view of operative and control part, ensuring coherence between models and meeting the requirements of the new industry. This approach is intended to guide the designer in modeling the manufacturing systems by integrating the concept of reconfiguration into system engineering.Then, developed models of different viewpoint are transformed according to predefined rules into holonic architecture models that bridge the gap between the conceptual modeling process and the simulation process. These holonic models are executable by the technology of multi-agent systems to facilitate their implementations. Afterwards, the designer will be able to verify and validate by simulation the criteria and key features of the reconfiguration in order to achieve the requested indicators. The obtained results show an effective reactivity to the internal and external disturbances with the most adequate configuration. We chose a reconfigurable manufacturing system which is the steel converter system to illustrate the utility and reliability of the proposed approach in different scenarios., Aujourd’hui, les industriels cherchent de nouvelles approches qui permettent aux concepteurs d’adapter efficacement les systèmes de fabrication face à un environnement incertain et perturbant. Le concept de la reconfiguration des systèmes de fabrication est proposé afin de trouver des solutions face à l’occurrence d’aléas au sein d’un système manufacturier complexe. Dans la littérature, l’intégration de la reconfiguration dès la phase de conception dans le cadre de l’ingénierie système en suivant une approche basée sur des normes et paradigmes commence à faire appel à plusieurs nouveaux travaux de recherche. Nous proposons une nouvelle approche basée sur l’ingénierie système pour concevoir les systèmes de production manufacturiers pour qu’ils soient reconfigurables du point de vue partie opérative et commande, en assurant la cohérence entre les modèles et en respectant les exigences de l’industrie nouvelle. Cette approche vise à guider le concepteur pour modéliser les systèmes manufacturiers en intégrant le concept de la reconfiguration dans le cadre de l’ingénierie système.Ensuite, les modèles développés des différents points de vue sont transformés suivant des règles prédéfinies vers des modèles d’architectures holoniques qui permettent de combler l’écart entre le processus de modélisation conceptuelle et le processus de simulation. Ces modèles holoniques sont exécutables par la technologie des systèmes multi-agents afin de faciliter leurs implémentations. Après, le concepteur sera capable de vérifier et valider par simulation les critères et les caractéristiques clés de la reconfiguration dans le but d’atteindre les indicateurs demandés. Les résultats obtenus montrent une réactivité efficace aux aléas internes et externes avec la configuration la plus adéquate. Nous avons choisi un système manufacturier reconfigurable qui est le système de conversion d’acier afin d’illustrer l’utilité et la fiabilité de l’approche proposée dans différents scénarios.

This work is aimed at applying holonic control system to poultry house travelling hopper feeders with the comparative cost analysis. It adopts HCBA which is suitable for controlling the reconfigurable automated processes. The feeder consists of parts for different types of poultry feeds dispensable from the feed reservoirs and carried around by travelling hoppers along the feed carts. The simulations were carried out using MATLAB and SIMATIC software. The responses of the speed of each traveling hopper were determined to be 1.04 sec, 1.91 sec and 0.0841% for rise time, settling time and percentage overshoot respectively. The parameters of the embedded controller in STEP 7 CONT_C FB41 data block translate to a constant gain of 10, integral time constant of 100 ms and derivative time constant of 280 ms. Visual results from the HMI show the system’s ability for customization, cooperation and autonomy for implementation of any poultry feeding program. The cost analysis shows that it is profitable for farm capacity of 10,000 birds and above with low labour cost and average annual energy cost of about N708,000. The feed wastage loss is reduced by 66% while depreciation is 10% as compared to cage system with belted conveyor feeder.

IF=3.035; International audience; Nowadays, industrials are seeking for models and methods that are not only able to provide efficient overall production performance, but also for reactive systems facing a growing set of unpredicted events. One important research activity in that field focuses on holonic/multi-agent control systems that couple predictive/proactive and reactive mechanisms into agents/holons. Meanwhile, not enough attention is paid to the optimization of this coupling. The aim of this paper is to depict the main research challenges that are to be addressed before expecting a large industrial dissemination. Relying on an extensive review of the state of the art, three main challenges are highlighted: the estimation of the future performances of the system in reactive mode, the design of efficient switching strategies between predictive and reactive modes and the design of efficient synchronization mechanisms to switch back to predictive mode. indicator of the production system, discrete-event observer, flexible manufacturing system.

In this paper, we present the system architecture of a flexible manufacturing planning and control system, named EtoPlan. The concept is based on the holonic control approach of building multiple and temporary hierarchies (holarchies). This paper describes the system architecture for flexible planning and control of activities and (groups of) Resources in a manufacture-to-order environment. The system architecture consists of generic control modules that can be applied on different hierarchical levels and for different kinds of manufacturing activities. The main function of the Resource Controller is the Determine Applicability function.

May 25 - May 27; International audience; Ambient 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.

International audience; New developments in production control can be grouped around two modes: distributed and centralised control. Interaction between these control modes can be seen as a B2M issue. We propose in this paper an alternative B2M architecture, using holonic products, in order to nable cooperation between centralised business and distributed manufacturing decision systems. We will first give the requirements of such a system, then outline the structure of the holonic product and finally study the possible interaction protocols between the products and the decision system.

Indexado ISI The formal specification of agent-based and holonic manufacturing control systems assumes a critical role in order to understand and synthesize those complex systems. This paper presents the formal specification of the coordination models for the ADACOR holonic control system. For this purpose, it is used High-Level Petri Nets to model the behavior of individual ADACOR entities, AUML interaction diagrams to represent the interaction between those entities and mailboxes structures to synchronize the evolution of the Petri net models associated to the holons. The authors would like to thank the European Commission and the partners of the Innovative Production Machines and Systems (I*PROMS;http://www.iproms.org/) Network of Excellence for their support.

To remain competitive, companies must react quickly to customer demands by improving their flexibility, agility, and reconfigurability while maintaining productivity and quality. On the other side, the current worldwide market competition forces companies to reconsider their organization, leading to the virtual enterprise and smart networked-enterprise models. In these circumstances, a major challenge is the migration from conventional factory floor control strategies to collaborative production automation and control systems. This article outlines new trends in manufacturing and describes the main concepts of the collaborative manufacturing control architecture ADACOR. It discusses how ADACOR supports integration and extension within the manufacturing value chain. The authors analyze ADACOR from the point of view of the collaborative manufacturing management paradigm, including how ADACOR fulfills the different specifications of the model's three axes.
