Full textAbstract:
Job shop scheduling, especially in machine intensive manufacturing is heavily reliant upon job assignment systems for the management of machines on the shop-floor. Considering the machines as the elements of a network in the shop-floor, similar approach could be extended to the elements of supply chain of the manufacturing enterprise. This approach, combined with relevant concepts of the agent-based and holonic systems, has caused motivation to this research, whose primary aim is proposing new job allocation models in multi-level manufacturing operations. That aim has been achieved by bringing the concept of topology of distributed systems into the current agent-based and holonic manufacturing systems. After presenting a conceptual holonic model of multi-level manufacturing operations for fulfillment of an external customer order, the work has focused on shop-floor level. Interaction protocol in multi-agent systems and its relation with the architecture of the agents’ network were studied and new models for task allocation were proposed in the context of a machine-intensive shop-floor. Having examined the models in the shop-floor, the best performing models were further customized and extended to manufacturing supply network (top-floor level). At the both levels, the research uses information and data from case studies of real-world manufacturing. The results obtained were very promising for a ring-like job allocation model, to improve the key performance indicators of operations at the both levels. Although the research seeks practical solutions in Manufacturing Systems, its developed concept on the platform of MAS topology might be utilized within other engineering fields that benefit from the agent technology.

Full textAbstract:
In real-word manufacturing environments, finding the right job sequences and their associated schedules when resource, precedence, and timing constraints are imposed is a difficult task. For most practical problems classical scheduling easily leads to an exponential growth in the number of possible schedules. Moreover, a decision time period of hours or even minutes is too long. Good solutions are often needed in real-time. The problem becomes even more complicated if changes, such as new orders or resource breakdowns, occur within the manufacturing system. One approach to overcome the challenges of solving classical scheduling problems is the use of distributed schemes such as agent or holonic-based control architectures.
This dissertation presents an innovative control architecture that uses the holonic concept, capable of delivering good solutions when applied in dynamic environments. The general holonic control framework presented in this research has specific characteristics not found in others reported so far. Using a modular approach it takes into account all the categories of hardware and software resources of a manufacturing system. Due to its modularity, the holonic control framework can be used for assigning and scheduling different task types, separately or simultaneously. Thus, it can be used not only for assigning and scheduling transport tasks, but also for finding feasible solutions to the job assignment and scheduling of processing tasks, or to better utilize the auxiliary equipment and devices in a manufacturing system.
In the holonic system, under real-time constraints, a feasible schedule for the material handling resources emerges from the combination of individual holon's schedules. Internal evaluation algorithms and coordination mechanisms between the entities in the architecture form the basis for the resultant schedules. The experimental results obtained show a percentage difference between the makespan values obtained using the holonic scheduling approach and the optimal values of under seven percent. Since current control systems in use in industry lack the ability to adapt to dynamic manufacturing environments, the holonic architecture designed and the tests performed in this research could be a part in the effort to build the foundations for the control systems of the next generation manufacturing systems.Ph.

Full textAbstract:
In the last decades significant changes in the manufacturing environment have been noticed: moving from a local economy towards a global economy, with markets asking for products with high quality at lower costs, highly customised and with short life cycle. In this environment, the manufacturing enterprises, to avoid the risk to lose competitiveness, search to answer more closely to the customer demands, by improving their flexibility and agility, while maintaining their productivity and quality. Actually, the dynamic response to emergence is becoming a key issue, due to the weak response of the traditional manufacturing control systems to unexpected disturbances, mainly because of the rigidity of their control architectures. In these circumstances, the challenge is to develop manufacturing control systems with autonomy and intelligence capabilities, fast adaptation to the environment changes, more robustness against the occurrence of disturbances, and easier integration of manufacturing resources and legacy systems. Several architectures using emergent concepts and technologies have been proposed, in particular those based in the holonic manufacturing paradigm. Holonic manufacturing is a paradigm based in the ideas of the philosopher Arthur Koestler, who proposed the word holon to describe a basic unit of organisation in biological and social systems. A holon, as Koestler devised the term, is an identifiable part of a (manufacturing) system that has a unique identity, yet is made up of sub-ordinate parts and in turn is part of a larger whole. The introduction of the holonic manufacturing paradigm allows a new approach to the manufacturing problem, bringing the advantages of modularity, decentralisation, autonomy, scalability, and re-use of software components. This dissertation intends to develop an agile and adaptive manufacturing control architecture to face the current requirements imposed to the manufacturing enterprises. The architecture proposed in this dissertation addresses the need for the fast reaction to disturbances at the shop floor level, increasing the agility and flexibility of the enterprise, when it works in volatile environments, characterised by the frequent occurrence of unexpected disturbances. The proposed architecture, designated by ADACOR (ADAptive holonic COntrol aRchitecture for distributed manufacturing systems), is based in the holonic manufacturing paradigm, build upon autonomous and cooperative holons, allowing the development of manufacturing control applications that present all the features of decentralised and holonic systems. ADACOR holonic architecture introduces an adaptive control that balances dynamically between a more centralised structure and a more decentralised one, allowing to combine the global production optimisation with agile reaction to unexpected disturbances. Nas últimas décadas têm-se assistido a mudanças significativas no ambiente de fabrico: evoluindo de uma economia local para um economia global, com os mercados a procurar produtos com elevada qualidade a baixos preços, altamente customizados e com um ciclo de vida curto.
Neste ambiente, as empresas de manufactura, para evitar o risco de perda de competitividade, procuram responder às solicitações dos clientes, melhorando a sua flexibilidade e agilidade, mantendo os mesmos índices de produtividade e qualidade. Na verdade, a resposta dinâmica à emergência está a tornar-se num assunto chave, devido `a fraca resposta a perturbações que os sistemas de controlo de fabrico tradicionais apresentam, principalmente devido à rigidez das suas arquitecturas de controlo.
Nestas circunstâncias, é fundamental o desenvolvimento de sistemas de controlo de fabrico com capacidades de autonomia e inteligência, rápida adaptação às mudanças, maior robustez à ocorrência de perturbações e fácil integração de recursos físicos e sistemas legados. Diversas arquitecturas usando conceitos e tecnologias emergentes têm sido propostas, em particular algumas baseadas no paradigma da produção holónica.
O paradigma da produção holónica é inspirado nas ideias de Arthur Koestler, que propôs a palavra holon para descrever uma unidade básica de organização de sistemas biológicos e sociais.
Um holon, de acordo com a definição de Koestler, é uma parte identificável do sistema com identidade única, composta por sub-partes e fazendo simultaneamente parte do todo. A introdução do paradigma da produção holónica permite uma nova abordagem aos sistemas de controlo de fabrico, trazendo vantagens de modularidade, descentralização, autonomia, escalabilidade e reutilização de componentes.
Esta dissertação pretende desenvolver uma arquitectura de controlo ágil e adaptativa que suporte os requisitos actuais impostos `as empresas de manufactura. A arquitectura proposta visa a necessidade de uma reacção rápida a perturbações, ao nível da planta fabril, melhorando a flexibilidade e agilidade da empresa quando esta opera em ambientes voláteis, caracterizados pela ocorrência frequente de perturbações inesperadas. A arquitectura proposta, designada por ADACOR (ADAptive holonic COntrol aRchitecture for distributed manufacturing systems), é baseada no paradigma da produção holónica e construída sobre holons autónomos e cooperativos, permitindo o desenvolvimento de aplicações de controlo de fabrico que apresentem todas as características dos sistemas descentralizados e holónicos.
A arquitectura holónica ADACOR introduz um controlo adaptativo que balança dinamicamente entre uma estrutura de controlo mais centralizada e uma mais descentralizada, permitindo combinar a optimização da produção com a ágil reacção a perturbações.

Le travail présenté dans cette thèse concerne le développement d'un Framework pour les Systèmes Multi-Agents Holoniques. Ce type de système se compose de structures auto-similaires appelées holons. Un ensemble de holons peut être vu, selon le niveau d'observation, comme une entité unique ou comme un groupe de holons en interactions. Pour concevoir un framework générique et modulaire, nous utilisons une approche organisationnelle. Nous définissons les comportements des entités du framework en termes de rôles et d'interactions. Le framework met l'accent sur la modélisation et la représentation de trois aspects importants d'un SMA Holonique. Structure et Gestion d'un Holon : cette partie du framework prend en compte l'organisation des membres et la gestion du super-holon. Une organisation spécifique est proposée pour définir les statuts des membres vis-à-vis de leur super-holon. Interactions dépendantes du Problème : Pour réaliser les buts et les tâches du super-holon, les membres doivent interagir et coordonner leurs actions. Ces comportements, dépendants du problème, constituent les organisations internes. Notre framework offre aussi la possibilité de modéliser ces aspects. Dynamique : La dynamique est une caractéristique inhérente des SMA. Le framework considère également deux caractéristiques intrinsèques aux SMA holoniques : la Fusion (création et intégration dans le super-holon) et l'Auto-Organisation. Chaque organisation est modélisée en utilisant le modèle Rôle-Interaction-Organisation (RIO). Ce modèle offre une spécification formelle des rôles et permet la vérification et la validation des spécifications. Le framework a été formellement spécifié et cette formalisation, nous a permis de prouver d'importantes propriétés importantes sur l'auto-organisation du système. Nous proposons également une méthodologie pour l'analyse et la conception des systèmes complexes basée sur la notion de "Vues du Système". Chaque vue se consacre à un aspect particulier du système, et est représentée par une holarchie. Deux applications illustrent les concepts présentés dans ce travail. La première applique le framework au cas du Maillage Adaptatif pour le dimensionnement de réseaux radiomobiles. Cette application illustre le raffinement de la partie auto-organisation du framework et la spécification formelle d'un problème réel. La deuxième présente quant à elle, l'application des SMA holoniques pour la simulation d'un important site industriel. Plusieurs holarchies sont utilisées pour capturer les interactions entre les chaînes de production et le trafic routier interne au site. Pour implémenter ces concepts nous proposons un ensemble de modules basés sur la plateforme MadKitThe work presented in this PhD thesis is concerned with the development of a framework for Holonic MultiAgent Systems. This type of systems consists in self-similar structures called holons. A set of holons may be seen, depending on the level of observation, as a unique entity or as a group of holons in interaction. In order to conceive a generic and modular modeling framework, we use an organizational approach. We define then the behavior of the frame work entities in terms of roles and their interactions. The framework is concerned with the modeling and representation of three important aspects of a Holonic MAS. Holon Structure and Management : This part of the framework considers how the members organize and manage the super-holon. It offers a specific organization whose roles define the status of the member from the super-holon's point of view. Goal-Dependent Interactions : In order to achieve the goals/tasks of the super-holon, the members must interact and coordinate their actions. These goal-dependent behaviors are called Internal Organizations and our framework also offers means to model these aspects of the super-holons functioning. Dynamics : Dynamics are inherent characteristics of MAS. The framework considers in particular two of the most attractive characteristics of Holonic MAS: Merging (Creating and Joining a super-holon) and Self-Organization. Each organization is modeled using the Role-Interaction-Organization (RIO) Model. This model offers a formal specification of roles that enables the validation and verification of the model. We have formally specified the framework. Based on this formalization we were able to prove important properties concerning the self-organization of the system. We propose some guidelines based upon this framework for the analysis and design of Complex Systems. Two applications illustrate the concepts presented. The first uses the framework to the Adaptive Meshing Problem applied to the dimensioning of radiomobile networks. It illustrates the refinement of a self-organization module and formal specification. The second presents the use of holonic MAS for the simulation of an important industrial plant. Multiple holarchies are used to capture the interaction between the production and traffic inside the plant. In order to implement these concepts we propose a set of modules based on the MadKit platform

Full textAbstract:
The present context and tendencies in modern production system, as mass customization, requires improvements with respect to the agility of the production organizations. In this sense, agile approaches have been proposed, such as the holonic approach. In Holonic Manufacturing System (HMS) the production entities, as resources and products, are envisaged with a type of intelligence. These smart-entities are called holons (HLs) whose intelligence is related to their autonomy and collaboration skills. The HMS also comprises a Holonic Control (HC) that must properly organize holon collaborations in order to become agile. Actually, HMS development requires engineering tools for design and testing. In this doctoral thesis, a meta-model for HC is proposed, whose instances are simulated within a particular tool called ANALYTICE II. This tool presents a clear separation between high-level control and emulated resources. Firstly, before the proposition of the HC meta-model, the resource holonification is proposed in this environment. Each Resource-HL is obtained by means of a virtual resource that provides data and services of an emulated-resource at a high level of control. Subsequently, the meta-model for HC over Resource-HLs following a process-driven production approach is proposed. The essence of the solution is based on Rule Base System (RBS) concepts being the causal relations of control dealt with by entities called Rules. The inference process in this RBS is realized through collaborations based upon notifications. The Resource-HLs notify the Rules about factual knowledge with respect to their states. Each Rule that is notified deliberates about the proper moment to execute some control action, as the coordination of a set of Resource-HLs, using causal knowledge. The inference occurs within a notification chain enabled by a group of Resource-HL agents and Rule agents. This kind of inference can be expected to provide advantages for the HC, such as high reactivity and entity decoupling. Furthermore, it allows for the creation of co-operative mechanisms for dealing with determinism and conflict issues. Moreover, this approach of rule-oriented control allows for coherent control implementation and expression. The control mechanisms emerge based on causal control knowledge expressed by experts in the Rules. Experts are exclusively concerned with the proper control knowledge needed for exploiting system flexibilities in order to increase system agility. Furthermore, some experts could even be artificial agents automatically dealing with knowledge of the Rules. Briefly, this process-driven HC solution concomitantly treats a set of control issues while also being a self-contained and open solution. Indeed, the solution openness allows its interpretation as a product-driven solution. The product-driven control is a tendency to reach agility by the decoupling of production demands and execution via entities like Smart-Product-HLs. Each Smart-Product-HL is concerned with a specific customized production order. The Smart-Product-HLs, with certain autonomy, use Resource-HLs to reach their production goals. In the meta-model interpretation, their interactions are organized by Rules for Resource-HL cooperation that avoids inappropriate system behavior. In this context, the execution of Rules depends upon the explicit Smart-Product-HL interest in their utilization. In some manner, each Smart-Product- HL deals with Rules as a kind of expert agent. The solution has been applied in a set of examples in ANALYTICE II presenting some simulation independence because each control instance is not aware that Resource-HLs and Smart-Product-HLs are simulated.

In manufacturing, the search for new techniques to improve the production is always a challenge. These techniques must be adapted to the dynamic environment. A point very dealt in this area is the transportation system which has, as one of its sub problems, the assigning tasks to the AGVs. To solve this problem, it is common to use vehicle dispatching, and these techniques are usually multicriteria. Although they are multi-criteria, is not common contemplate criteria of different sectors of the factory, which could indicate conflicting strategies. Another point that influences the performance of the manufacturing is the control architecture. Traditionally, this architecture is centralized or decentralized, and have pros and cons. To achieve benefits from both traditional architectures, new architectures have been pursued; a widely used option is the holonic. This research presented a holonic architecture control for the dispatch of vehicles using multiple criteria rules, given optimization criteria from different sectors of the factory and providing a global optimization bias. Analyzes were performed to assess the adhesion of the proposed holonic architecture in the manufacturing environment, achieving the inclusion of new elements naturally, analyzing the behavior when an unpredicted event occurs and enabling compliance with different optimization variables belonging to different sectors of the factory.
Na manufatura, a busca por novas técnicas para melhorar a produção é sempre um desafio. Estas técnicas devem se adequar ao ambiente dinâmico da manufatura. Um ponto tratado neste âmbito é o sistema de transporte, que tem como um de seus subproblemas a atribuição de tarefas para os AGVs. Para a resolução deste problema, é comum utilizar técnicas de despacho de veículos, sendo que estas técnicas geralmente são multicritério. Apesar de serem multicritério, não é comum contemplarem critérios de diferentes setores da fábrica, o que poderia indicar estratégias conflitantes. Outro ponto que influencia no desempenho da manufatura é a arquitetura de controle. Tradicionalmente, a arquitetura é centralizada ou descentralizada, apresentando prós e contras. Existe uma busca sobre novas arquiteturas para atingir benefícios proveniente das duas tradicionais; uma opção muito usada é a holônica. Neste trabalho é apresentada uma arquitetura holônica de controle para o despacho de veículos usando regras multicritério, atendendo critérios de otimização de diferentes setores da fábrica e proporcionando um viés de otimização global. Foram realizadas análises para avaliar a aderência da arquitetura holônica proposta no ambiente de manufatura, atendendo à inclusão de novos elementos de maneira natural, analisando o comportamento diante de eventos não programados e possibilitar o atendimento de diferentes variáveis de otimização pertencentes à diferentes setores da fábrica.

De nos jours, avec l’émergence d’objets et de voitures connectés, les systèmes de trafic routier deviennent de plus en plus complexes et présentent des comportements hiérarchiques à plusieurs niveaux de détail. L'approche de modélisation multiniveaux est une approche appropriée pour représenter le trafic sous plusieurs perspectives. Les modèles multiniveaux constituent également une approche appropriée pour modéliser des systèmes complexes à grande échelle comme le trafic routier. Cependant, la plupart des modèles multiniveaux de trafic proposés dans la littérature sont statiques car ils utilisent un ensemble de niveaux de détail prédéfinis et ces représentations ne peuvent pas commuter pendant la simulation. De plus ces modèles multiniveaux considèrent généralement seulement deux niveaux de détail. Très peu de travaux se sont intéressés à la modélisation dynamique multiniveau de trafic.Cette thèse propose un modèle holonique multiniveau et dynamique du trafic à grande échelle.La commutation dynamique des niveaux de détail lors de l’exécution de la simulation permet d’adapter le modèle aux contraintes liées à la qualité des résultats ou aux ressources de calcul disponibles.La proposition étend l'algorithme DBSCAN dans le contexte des systèmes multi-agents holoniques. De plus, une méthodologie permettant la commutation dynamique entre les différents niveaux de détail est proposée. Des indicateurs multiniveaux basés sur l'écart type sont aussi proposés afin d'évaluer la cohérence des résultats de la simulationNowadays, with the emergence of connected objects and cars, road traffic systems become more and more complex and exhibit hierarchical behaviours at several levels of detail. The multilevel modeling approach is an appropriate approach to represent traffic from several perspectives. Multilevel models are also an appropriate approach to model large-scale complex systems such as road traffic. However, most of the multilevel models of traffic proposed in the literature are static because they use a set of predefined levels of detail and these representations cannot change during simulation. Moreover, these multilevel models generally consider only two levels of detail. Few works have been interested on the dynamic multilevel traffic modeling.This thesis proposes a holonic multilevel and dynamic traffic model for large scale traffic systems. The dynamic switching of the levels of detail during the execution of the simulation allows to adapt the model to the constraints related to the quality of the results or to the available computing resources.The proposal extends the DBSCAN algorithm in the context of holonic multi-agent systems. In addition, a methodology allowing a dynamic transition between the different levels of detail is proposed. Multilevel indicators based on standard deviation are also proposed in order to assess the consistency of the simulation results

Full textAbstract:
A área do petróleo é uma das que mais podem se beneficiar da melhoria de eficiência da gestão da cadeia de suprimentos. Entretanto, o comportamento dinâmico de tais cadeias é muito complexo para ser modelado de forma analítica. Por outro lado, estas cadeias mostram várias características intrínsecas em comum com sistemas multiagentes, que oferecem a flexibilidade necessária para modelar as complexidades e a dinâmica das cadeias de suprimentos reais sem a necessidade de premissas muito simplificadoras. Como o problema de gerenciamento da cadeia de suprimentos apresenta uma estrutura recursiva, torna-se ainda mais conveniente usar um modelo baseado em agentes holônicos, que mostram uma estrutura do tipo fractal. Além disso, o tipo de relacionamento entre as entidades da cadeia e a necessidade de uma otimização global sugerem modelar suas interações na forma de restrições. Por esta razão, esta tese propõe um modelo distribuído de otimização através da definição de um novo problema denominado Problema de Satisfação de Restrições Holônico com Otimização (HCOP), que é baseado nos conceitos do Problema de Satisfação de Restrições Distribuído com Otimização (DCOP) e agentes holônicos. Além disso, foi desenvolvido um meta-algoritmo baseado no algoritmo DTREE para solucionar este tipo de problema, onde vários algoritmos disponíveis de otimização centralizados podem ser embutidos e integrados de tal forma a obter a configuração mais adequada para cada caso. Assim, uma típica cadeia de suprimentos da indústria do petróleo foi modelada como um HCOP, e foi desenvolvido um protótipo que implementa o meta-algoritmo proposto em um ambiente que integra sistemas de otimização de produção e logística, que são representativos em relação a situações reais. Finalmente foram realizados experimentos sobre um estudo de caso da empresa PETROBRAS, que permitiram a verificação da viabilidade deste modelo e a comprovação de suas vantagens em relação às abordagens convencionais.The oil area is one of those that may most benefit from the improved efficiency of supply chain management. However, the dynamic behavior of such chains is too complex to be modeled analytically. Moreover, these chains show several intrinsic characteristics in common with multiagent systems, which offer the required flexibility to model the complexities and dynamics of real supply chains without rather simplifying assumptions. As the problem of managing the supply chain has a recursive structure, it becomes more convenient to use a model based on holonic agents, which show a fractal-type structure. Furthermore, the type of relationship between entities in the chain and the need for global optimization suggest to model their interactions in the form of constraints. For this reason, this thesis proposes an optimization distributed model by defining a new problem called Holonic Constraint Optimization Problem (HCOP), which is based on concepts from Distributed Constraint Satisfaction Optimization Problem (DCOP) and holonic agents. In addition we developed a meta-algorithm based on DTREE algorithm for solving this type of problem, where several algorithms available for centralized optimization algorithms can be embedded and integrated so as to obtain the most suitable configuration for each case. Thus, a typical supply chain of the petroleum industry was modeled as a HCOP, and we developed a prototype that implements the meta-algorithm in an environment that integrates the optimization systems for production and logistics, which are representative in relation to actual situations. Finally experiments were performed on a case study of the company PETROBRAS, which allowed the verification of the feasibility of this model and the proof of their advantages over conventional approaches.

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 scénariosToday, 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

Le monde des entreprises est profondément soumis à un ensemble de contraintes toujours plus exigeantes provenant d’une part des clients, exigeant des produits plus personnalisables, de qualité supérieure et à faible coût, et d’autre part des aléas internes auxentreprises, comprenant les pannes machines, les défaillances humaines, la fluctuation de la demande, les fréquentes variations de production. Cette thèse propose une architecture de contrôle de systèmes de production, basée sur les principes holoniques développées dans l’architecture ADACOR (ADAptive holonic COntrol aRchitecture), et l’étendant en s’inspirant des théories de l’évolution et en utilisant des mécanismes d’auto-organisation. L’utilisation des théories de l’évolution enrichit l’architecture de contrôle en permettant l’évolution de deux manières distinctes, en réponse au type et au degré de la perturbation apparue. Le premier mode d’adaptation, appelé auto-organisation comportementale, permet à chaque entité qui compose le système d’adapter dynamiquement leur comportement interne, gérant de cette façon de petites perturbations. Le second mode, nommé auto-organisation structurelle, traite de plus grandes perturbations, en permettant aux entités du système de ré-organiser leurs relations, et par conséquent modifier structurellement le système. L’architecture holonique auto-organisée de contrôle de systèmes de production proposée dans cette thèse a été validée sur une cellule de production flexible AIP-PRIMECA. Les résultats ont montré une amélioration des indicateurs clés de performance par rapport aux architectures de contrôle hiérarchiques et hétérarchiquesThe manufacturing world is being deeply challenged with a set of ever demanding constraints where from one side, the costumers are requiring products to be more customizable, with higher quality at lower prices, and on other side, companies have to deal on a daily basis with internal disturbances that range from machine breakdown to worker absence and from demand fluctuation to frequent production changes. This dissertation proposes a manufacturing control architecture, following the holonic principles developed in the ADAptive holonic COntrol aRchitecture (ADACOR) and extending it taking inspiration in evolutionary theories and making use of self- organization mechanisms. The use of evolutionary theories enrich the proposed control architecture by allowing evolution in two distinct ways, responding accordingly to the type and degree of the disturbance that appears. The first component, named behavioural self- organization, allows each system’s entity to dynamically adapt its internal behaviour, addressing small disturbances. The second component, named structural self-organization, addresses bigger disturbances by allowing the system entities to re-arrange their rela- tionships, and consequently changing the system in a structural manner. The proposed self-organized holonic manufacturing control architecture was validated at a AIP-PRIMECA flexible manufacturing cell. The achieved experimental results have also shown an improvement of the key performance indicators over the hierarchical and heterarchical control architecture

Aujourd'hui, dans un monde globalisé, la conception des produits est en train de basculer vers la conceptiondistribuée multi-sites. En effet, la complexité des produits avec des contraintes économiques et d'ingénierie ontaccéléré la transformation et l'organisation des activités de conception en service-orientés dans un réseau distribué.Alors, la conception pour la configuration des produits émerge comme un outil efficace pour résoudre les nouveauxdéfis de la conception des produits. Beaucoup de recherches sur la conception pour la configuration considèrent leproblème de la conception pour la configuration uniquement comme un problème d'arrangement des composants.En effet, le processus de conception implique de multiple-métiers, la distribution des métiers et des acteurs, etl'interaction dans un environnement dynamique et incertain. De plus, nous pensons que la structure interne duprocessus de conception est une image homomorphe des discontinuités du produit perçu. En considérant l'espacede la conception pour la configuration comme multi vues, multi dimensionnels et incertain, cette thèse porte surl'étude de la conception pour la configuration comme un problème holistique.Nous avons proposé à étudier : (1) appréhender et modéliser la conception pour la configuration comme unproblème de recherche de consensus entre différents métiers ; (2) appréhender et modéliser les relations intra etinter domaines considérant la conception pour la configuration comme un problème holistique ; (3) formaliser lesgrammaires génératives pour la modélisation de produit dans les deux principaux espaces : fonctionnel et structurelet (4) modéliser les liens entre ces deux espaces à l'aide du concept d'holon de conception. A partir de cesconsidérations, nous établissons les hypothèses les plus importantes de notre recherche : (a) Hypothèse de multivues; (b) Hypothèse de flou ; (c) Hypothèse de dérivation ; (d) Hypothèse holistique et (e) Hypothèse d'attracteur.Nous avons décrit un modèle de conception pour la configuration dans lequel les aspects d'optimisation desconfigurations et la recherche des noyaux des configurations sont intégrés. D'ailleurs, nous avons proposé desgrammaires fonctionnelles floues graphes et des grammaires fonctionnelles floues formelles pour représentergraphiquement et formellement les structures fonctionnelles de produit. Nous avons aussi proposé une approche demodélisation holonique des configurations. Les concepts d'Holon Conception Floue et de l'Attracteur Flou sontproposés pour comprendre la coévolution dans la conception pour la configuration. Nous avons étudié un casindustriel de la conception pour la configuration à l'aide des modules pour un groupe motopropulseurProduct design is switching to the multi-site distributed design. Indeed, the complexity of products with engineeringand economic constraints have accelerated the transformation and organization of design activities into serviceorientedin a distributed network. So, design for product configuration emerges as an effective tool to address thenew challenges of product design. Many researches on design for configuration consider the design problem only asa problem of arrangement of components. Indeed, the design process involves multi-trades, distribution of tradesand actors, and interaction in a dynamic and uncertain environment. Moreover, we believe that the internal structureof the design process is a homomorphic image of the product perceived discontinuities. Considering the space ofthe design for the configuration as multi-views, multi-dimensional and uncertain, this thesis focuses on the study ofdesign for the configuration as a holistic problem.We proposed to study: (1) understand and model design for configuration as a consensus-building problem betweendifferent trades; (2) understand and model the relationships within and between domains considering the design forconfiguration as a holistic problem; (3) formalize the generative grammars for product modeling in two main spaces:functional and structural and (4) model the links between these two spaces with the concept of design holon. Fromthese considerations, we establish the most important assumptions of our research: (a) Assumption of multi-view;(b) Assumption of fuzzy; (c) Assumption of derivation; (d) Holistic assumption and (e) Assumption of attractor.We have described a design model for configuration wherein the optimization aspects of configurations andsearching of configurations cores are integrated. Moreover, we proposed fuzzy graphs functional grammars andformal fuzzy functional grammars to represent formally and graphically the functional structures of product. We alsoproposed an approach of holonic modeling for configurations. The concepts of Fuzzy Design Holon and FuzzyAttractor are proposed to understand the co-evolution in design for configuration. We studied an industrial case ofdesign for configuration using modules of a power train

Thesis (MScEng)-- Stellenbosch University, 2013.ENGLISH ABSTRACT: This work entails a study of the control software of transportation systems for use in recon gurable manufacturing systems (RMSs). Various control approaches are considered, with the focus on enhancing recon gurability. The work is unique in the sense that the RMS is designed to manufacture small parts/products and is meant to be used in developing countries. Manufacturing systems that can ensure product quality and delivery, are a critical need in countries where the bulk of manufacturing systems function with manual labour. RMSs and holonic manufacturing systems (HMSs) are identi ed as concepts that can potentially compete with manual manufacturing systems. The competing system must thus have a low initial adoption risk, be able to adapt to changing product functionality and demands, and have a comparable throughput rate. IEC61311-3, IEC64199 function block and agent-based control architectures are evaluated. The control software is tested on an experimental conveyor system. The thesis shows that IEC61131-3 and IEC64199 architectures are advantageous in lower levels of control. IEC64199 function blocks provide human interface and development tools and simpli es the distribution of control. The human interface and development tools of IEC64199 function blocks may prove bene cial in providing system monitoring and rapid low skilled adaptation of the control system, increasing recon gurability of systems in under-developed countries. Unfortunately, the low maturity of the development environments for IEC64199 function blocks is a limitation. It is shown that an IEC64199 function block controller becomes complex as the actuator/sensor count exceed 10. Agent-based systems o er reliable control and powerful communication tools but requires a higher level of expertise than IEC64199 function blocks. Agent-based systems are proposed for the core high level control. Complex systems can be controlled with agents and intelligence can be added to control systems in a recon gurable way. For the recon gurable control of large manufacturing systems, agent-based control was found to be superior to IEC64199 function blocks.
AFRIKAANSE OPSOMMING: Hierdie werk behels 'n studie in die beheersagteware van vervoerstelsels vir die gebruik in herkon gureerbare vervaardigingstelsels. Verskeie benaderings word oorweeg, met die fokus op die verbetering van herkon gureerbaarheid. Die werk is uniek in die sin dat die herkon gureerbare vervaardigingstelsel ontwerp is vir die vervaardiging van klein onderdele/produkte en is bedoel vir die gebruik in die ontwikkelende lande. Vervaardigingstelsels wat die kwaliteit van die produk en a ewering kan verseker, is 'n kritieke behoefte in die lande waar die grootste deel van die vervaardiging met handearbeid gedoen word. Herkon gureerbare vervaardigingstelsels en holoniese vervaardigingstelsels is geïdenti seer as konsepte wat moontlik kan meeding met die handmatige produksie-stelsels. Die mededingende stelsel moet dus 'n lae aanvanklike aannemingsrisiko hê, in staat wees om te kan aanpas by die veranderende produk funksionaliteit en aanvraag, en 'n vergelykbare deurvloeikoers kan lewer. IEC61311-3, IEC61499 funksie-blok en agent-gebaseerde beheer argitekture word geëvalueer. Die beheer sagteware is getoets op 'n eksperimentele vervoerband stelsel. Die tesis toon dat IEC61131-3 en IEC61499 argitekture voordelig is in die laër vlakke van beheer. IEC61499 funksie-blokke voorsien menslike koppelvlak en ontwikkelings-gereedskap, en vereenvoudig die verspreiding van beheer. Die menslike koppelvlak en ontwikkelings-gereedskap van die IEC61499 funksieblokke is moontlik voordelig in die voorsiening van stelselmonitering en vinnige laag-geskoolde aanpassing van die beheer stelsel. Dit mag dus moontlik die herkon gureerbaarheid van stelsels, in onder-ontwikkelde lande, verhoog. Die lae vlak van volwassenheid van die ontwikkelingsomgewings vir IEC61499 funksie-blokke verlaag hul bruikbaarheid. Daar word aangetoon dat IEC61499 funksie-blok beheerders baie kompleks raak as die hoeveelheid van aktueerders en sensors meer as 10 raak. Agent-gebaseerde stelsels bied betroubare beheer, en kragtige kommunikasie-gereedskap, maar vereis 'n hoër vlak van kundigheid as IEC61499 funksie-blokke. Agent-gebaseerde stelsels word voorgestel vir die hoëvlak beheer. Komplekse stelsels kan beheer word met agente en intelligensie kan bygevoeg word om stelsels te beheer in 'n herkon gureerbare manier. Dit was gevind dat agent-gebaseerde beheer beter is as IEC61499 funksie-blok beheer vir die herkon gureerbare beheer van groot vervaardigings stelsels.

Ces deux dernières décennies, les systèmes embarqués ont été introduits dans de nombreux domaines d'application (transport, industrie, habitat, médical...). Ces systèmes se sont vu confier des tâches plus importantes pour délivrer de nouveaux services aux utilisateurs avec des délais de mise sur le marché toujours plus courts et à moindre coût. L'intégration rapide de ces systèmes au sein de produits manufacturés est un avantage concurrentiel pour les industriels. Cependant, les pannes associées à ces systèmes et le niveau de complexité croissant des équipements ont rendu les interventions de maintenance bien plus délicates. L'identification des causes de certaines pannes représente actuellement un véritable challenge dans les activités de la maintenance. Elles entrainent une indisponibilité excessive des équipements.Cette thèse propose une architecture générique de surveillance "active" pour l'aide à la maintenance de systèmes mobiles. Cette architecture repose sur des entités de surveillance "intelligentes" capables d'évaluer l'état de santé des équipements surveillés. Notre contribution se situe à la rencontre de différentes communautés de Recherche et s'appuie notamment sur des concepts développés par lacommunauté PHM (Pronostics and Health Management).L'architecture proposée est mise en œuvre et appliquée a la surveillance d'un système réel de transport ferroviaire dans le cadre du projet SURFER (SURveillance active FERroviaire) conduit par Bombardier-Transport.

Les travaux effectués dans le cadre de cette thèse porte sur le contrôle intelligent, isoarchique et multicritère de flux de personnes dans une zone fermée. Nous proposons un système de contrôle basé sur la biométrie multimodale et le RFID qui sont deux techniques complémentaires pour une sécurisation robuste et flexible du flux de personnes. La biométrie multimodale est utilisée pour une reconnaissance plus fiable des individus, et le RFID pour la sécurisation et le stockage des informations identitaires des personnes à surveiller. Ce système est complètement décentralisé et la décision concernant une demande d'accès est prise de manière autonome au niveau de chaque porte de chaque zone sous contrôle. Les entités internes participantes au processus de prise de décision répondent à des concepts exprimés via le paradigme holonique. L'ouverture automatique d'une porte est conditionnée à la conjonction de plusieurs critères. Une méthode d'aide multicritère à la décision est ainsi déployée au sein de chaque porte d'accès pour fusionner les réponses des identifications biométriques et pour traiter en temps réel les demandes d'autorisation d'accès. Tout d'abord, un état de l'art a été réalisé sur la biométrie, la multimodalité biométrique, la technologie RFID et les systèmes de contrôle d'accès physique. Ensuite, un système de contrôle intelligent, isoarchique et multicritère a été proposé, intégrant l'utilisation simultanée de la multimodalité biométrique et du RFID. Enfin, un démonstrateur du système a été implémenté dans le cadre du contrôle de flux de détenus dans une prisonThe proposed work deals with the intelligent control, isoarchic and multicriteria of people flow in a restricted area. Our proposal is a control system based on a multimodal biometrics and RFID which are considered as two secured complementary techniques for robust and flexible people flow control. Multimodal biometrics is used for more reliable individual recognitions and the RFID for securing and storing supervised individuals identity information. This system is completely decentralized and the decision related to a control access request is made autonomously at each gate of each controlled area. The internal entities which participate to the decision making process respond to the holonic paradigm concepts and principles. The automatic gate opening is conditioned with several criteria conjunction (biometrics identifications, RFID identification, access permissions, authorized paths, status of the zone at time t, etc.). A multicriteria decision aid method is thus deployed in each access gate to merge biometrics identifications responses and to automatically treat the real-time access authorization requests. First, a state of art related to the biometric recognition, the contribution of multimodal biometric, the RFID technology and the physical access control based on biometric, was done. Then, an intelligent, isoarchic and multicriteria control of people flow system was proposed, including the use of multimodal biometric and RFID. At the end, a system simulation test bed was implemented to control prisoners flow in a jail. It supports the integration of various biometrics and RFID technologies

La maintenance de flottes de systèmes mobiles dans le monde du transport et de la logistique revêt de nos jours une importance croissante de par l’augmentation des attentes des exploitants et opérateurs en termes de sécurité, de fiabilité, de suivi, de diagnostic et de maintenance de ces systèmes. Dans ce contexte, Les mainteneurs des flottes doivent souvent faire face à d'énormes quantités de données brutes, informations et événements de surveillance liés aux contexte de leurs systèmes. De plus, ces événements, données et informations manquent souvent de précision et sont souvent contradictoires ou obsolètes. Enfin, le degré d'urgence des décisions de maintenance est rarement pris en compte. Ce travail est consacré à la proposition et à la mise au point d’une architecture de surveillance pour l’aide à la maintenance d’une flotte de systèmes mobiles. Cette architecture, appelée EMH², est destinée à faciliter le diagnostic et le suivi de ce type de flotte. Elle est construite sur les principes holoniques, des plus bas (capteurs) aux plus hauts niveaux (ensemble d’une flotte de systèmes mobiles). Elle se base également sur une standardisation des événements traités afin de traiter les données de manière générique. Cette architecture, indépendante des types de systèmes surveillés et de leur niveau hiérarchique, peut devenir l'épine dorsale d’une stratégie efficace de maintenance proactive d’une flotte. Une méthodologie de déploiement est ainsi proposée. Une étude en simulation et une application sur une flotte de 10 trains actuellement en service est présentéeThe maintenance of mobile systems fleets in the world of transport and logistics is of increasing importance today due to the increasing expectations of operators in terms of safety, reliability, monitoring, diagnosis and maintenance of these systems. In this context, fleet maintainers often have to deal with huge amounts of raw data, information and monitoring events related to the context of their systems. Moreover, these events, data and information are often lack precision and often contradictory or obsolete. Finally, the urgency of maintenance decisions is rarely taken into account. This work is devoted to the proposal and the development of a monitoring architecture to help maintain a fleet of mobile systems. This architecture, called EMH², is intended to facilitate the diagnosis and monitoring of this type of fleet. It is built on holonic principles, from the lowest (sensors) to the highest levels (a whole fleet of mobile systems). It is also based on a standardization of processed events in order to process the data generically. This architecture, independent of the types of systems monitored and their hierarchical level, can become the backbone of an effective strategy for proactive fleet maintenance. A deployment methodology is thus proposed. A simulation study and an application on a fleet of 10 trains currently in service is presented

Estimant qu'il est nécessaire de fonder la valeur intrinsèque de la nature et constatant l'insuffisance des pistes tracées par Baird Callicott pour ajuster son axiologie subjective moderne à un cadre de pensée postmoderne, j'entreprends de repenser ses notions de sujet et de valeur intrinsèque afin d'y intégrer non seulement l'invalidation écologique-quantique d'une séparation tranchée entre sujet et objet, mais également des éléments prégnants de la pensée postmoderne :la contextualisation, le constructivisme, et l'aperspectivisme découlant de ces deux traits (la pensée ne peut plus indûment privilégier une perspective particulière). J'utilise pour cela comme outil heuristique la théorie intégrale de Ken Wilber, et mets à profit une série d'analyses et de concepts novateurs inscrits dans une post-métaphysique intégrale, afin de proposer une voie de dépassement au dualisme inhérent à l'axiologie de Callicott et d'équilibrer son approche foncièrement matérielle de l'ontologie morale et du soi relationnel par et au sein d'un holisme intégral (extérieur et intérieur). Celui-ci repose sur la ré-introduction des intériorités du monde :le holisme n'est en effet pas simplement un multiplexe de relations internes entre surfaces matérielles mais également, et nécessairement, le multiplexe des relations intérieures qui co-constituent toute entité, tout holon.
Un holon désigne un tout-partie – à la fois entièreté persistante en relation avec d'autres entièretés et partie constituante d'une entièreté plus profonde – qui possède donc intrinsèquement une dimension individuelle et une dimension collective. Celles-ci se doublent de dimensions extérieures (aspects du holon accessibles à l'observation par les sens physiques ou leurs extensions) et intérieures (aspects du holon qui échappent à l'observation matérielle et requièrent, pour leur appréhension, dialogue et interprétation).
Je préconise d'intégrer aux notions de sujet et de valeur intrinsèque ces quatre dimensions co-constitutives de tout holon, irréductibles les unes aux autres, et nécessairement impliquées pour tout référent. L'intersubjectivité, littéralement intrinsèque à tout rapport au monde comme à tout référent, en elle-même irréductible à des composantes matérielles, représente le dépassement des dualismes modernes en même temps que la ré-introduction en propre de l'intériorité inhérente du monde. Atomisme et holisme sont transcendés en une approche intégrale qui réinscrit, en regard des relations internes entre surfaces matérielles, les relations intérieures qui les agencent. Par le biais de la théorie intégrale de Wilber, je propose donc de réconcilier l'axiologie de Callicott et sa théorie de la valeur intrinsèque de la nature avec un cadre de pensée postmoderne réhabilitant les intériorités du vivant.
---------------
Considering it necessary to articulate and to ground an understanding of the intrinsic value of nature, and finding that Callicott's proposals for adjusting his modern subjective axiology to a postmodern framework fall short on several accounts, I set about to rethink and reexamine his notions of subject and intrinsic value so as to have them integrate not only the ecological-quantic invalidation of the modern subject-object dichotomy but also some prominent features of postmodern thought :contextualism, constructivism, and, following those, aperspectivism (intenability of unduly privileging a single perspective).
To this end, I make use of Ken Wilber's Integral Theory as a heuristic tool and take advantage of several innovative analysis and concepts, set in the context of an integral post-metaphysics, in order to suggest a way of transcending the dualism inherent to Callicott's axiology whilst allowing for the fundamentally material conception of his moral ontology and relational self to be balanced by and within an integral holism (exterior and interior). This means re-introducing the world's interiorities :holism isn't simply about a multiplex of internal relations between material surfaces but also, and necessarily, about the multiplex of interior relations that are co-constitutive of any entity, of any holon.
A holon designates a whole-part – both a persisting entirety or whole involved in relations with other entities and a constitutive part of deeper wholes – that intrinsically possesses an individual and a collective dimension. These are both further comprised of exterior (aspects of the holon that are accessible to observation by the physical senses or their extensions) and interior (aspects of the holon that evade material observation and require, for their apprehension, a dialogue and interpretation) dimensions.
Intersubjectivity, which is literally intrinsic both to any relation with the world and to the co-creation of any referent, and is in itself irreducible to whatever material component, appears as the fundamental overcoming of modernity's dualisms. Concurrently, a holonic understanding of the notions of subject and of intrinsic value is recommended, such that the main constitutive and irreducible dimensions of any holon become foundational to both these notions. Atomism and holism are transcended into an integral approach that acknowledges the interior relations prominent in giving agency and meaning to the various internal relations between material surfaces focused on by Callicott. Through Wilber's Integral Theory, I thus suggest the means of reconciling Callicott's axiology and theory of the intrinsic value of nature with a postmodern framework that rehabilitates life's interiorities.

On the basis of extensive practical experience in the development of agent-based systems for manufacturing execution and agent-based systems in general, a reference model for holonic execution known as HERA (Holonic Execution Reference Architecture) is developed. The model is characterised by a focus on holarchy - Koestler's Janus Effect (Koestler, 1967) is explicitly captured. However, the Holonic Manufacturing Systems (HMS) Consortium's view of a holon having an information processing part and a physical part (Brennan and Norrie, 2003) is also present. We refer to these parts as the behaviour and the embodiment respectively.

In the semiconductor supply chain, information exchanging is a very important topic. How to smoothly exchange the information of different formats inside the company? How to promptly fulfill information requests from the cooperative companies? For securing those highly-sensitive information and seizing business opportunities, the difficult and important questions like these are needed to be considered thoroughly. Therefore, we build the Holonic Information Exchange System (HIES) to efficiently translate and dispatch extensive information of different formats among Communication Holon (CH), Data Warehouse (DWH), Manufacturing Execution System (MES), and Virtual Manufacturing (VM) system. This supply chain is designed to adopt the communication specification set by RosettaNet. Moreover, the major component of HIES, Exchange Holon, is designed to inherit the Generic Holon that possessed all the basic properties of Holon and was successfully developed in our previous work. In order to improve and enhance the stability of this information exchanging system, the HIES is empowered with the abilities of error detecting and function recovery for each message flow under processing and Exchange Holon itself. We believe that the HIES is one of the best solutions for the enterprises to efficiently and stably exchange and integrate internal information.

A Holonic Manufacturing System (HMS), which is designed to realize the agile manufacturing enterprise, must be able to integrate the entire range of manufacturing activities from market demands, design, modeling, through production. These entire activities are implemented by several distributed sites. In order to effectively integrate these distributed sites, in this project, we adopt distributed object, mobile object, and object web technologies as well as the holon and holarchy concepts derived from studying social organizations and living organisms to develop a Holonic Information Coordination System (HICS). The major role of HICS is a Communication Holon. This Communication Holon processes the basic holonic attributes which includes intelligence, autonomy, and cooperation. Each distributed site (e.g. Virtual Manufacturing Site and Manufacturing Site) must own a Communication Holon as the bridge to conduct information coordination and communication among the distributed sites of the HMS. The customer site must also own a Communication Holon so as to place an order and query order-related information. This HCIS is designed to meet the future requirements of supply chain information integration for a virtual enterprise.

As the demand for new products to have various functions increases and only small quantity of products are required, also as the competition pressure continues to grow, the manufacturing industry needs a highly flexible manufacturing system to cope with the complicated manufacturing environment. To meet the above requirements, we adopt the concepts that were derived from the study of social organizations and living organisms, and translate them into a set of appropriate concepts, such as Holon and Holarchy, for manufacturing industries. Holon and Holarchy possess the properties of intelligence, autonomy, cooperation, reconfigurability, and extensibility. Besides, the systems shall also possess the properties of security certification and error recovery. Based on these properties, in this project, a systematic approach is proposed to develop a Holonic Manufacturing Execution System (HMES) for semiconductor industry. This systematic approach is started with system analysis by collecting domain requirements and analyzing domain knowledge. Then the HMES Holarchy is designed by the process of constructing abstract object model based on domain knowledge, partitioning application domain into functional Holons, identifying generic parts among functional Holons; developing the Generic Holon, defining Holarchy messages, define Holarchy framework of HMES, and finally designing functional Holons based on the Generic Holon. This project adopts the technologies of distributed object-oriented approach with CORBA infrastructure, N-tier client/server architecture, knowledge base, and data warehousing to develop the entire Holonic Manufacturing Execution System. Finally, we demonstrate the feasibility and capability of HMES by designing and implementing the Scheduling Holon and WIP Holon.

This paper presents an approach that can be applied in the design of holonic manufacturing systems (HMSs). The development combines concepts from object-oriented analysis, software architecture design, object-oriented simulation and software implementation. In object-oriented analysis, the object-oriented modeling technology is proposed as a method for capturing and representing the specification of holons with the features of reusability, re-configurability and scalability. A holonic design pattern (CWS holon) is suggested to cope with the dynamic environment without the need for major change in control software and hardware during run-time. The object-oriented simulation is used to bridge the gaps existing between object-oriented analysis/design and software programming. In software implementation, the 3-tier architecture is proposed to implement the idea of the holonic manufacturing control system based on Web-based technology. In this paper, we both present problems and build models required for the development of holonic manufacturing control systems (HMCSs). The specific tasks are: (1) to propose an appropriate software architecture for HMCSs, (2) to define the specification of a cell-workstation (CWS) holon, (3) to advocate the use of design pattern to build reusable, reconfigurable and extendible control software for the CWS holon, (4) to design the cooperative mechanism (contract net) for better system adaptability, (5) to upgrade communication capability of exiting CNC machines from RS232C to TCP/IP based on Ethernet. Finally, to demonstrate the proposed development, a paradigm of a holonic flexible manufacturing system was designed and implemented. Not only does this methodology require less time and cost in evolutionary control software, it also greatly enhances the competitive capability of companies operating on a flexible basis.

The Intelligent Building/Home System (IBS) enhances the human life style. It makes our life more comfortable, efficient, and safety. With increasing of computer, communication network, and building automation protocol, the IBS has been possible to implement in every building soon. The critical problem to the IBS that can be a popular one is that how to construct the IBS quickly and efficiently. So we proposed a systematical method and model to construct an IBS and a control kernel to integrate it. After that, the IBS will be easy to construct and it will be a flexible and scalable system. An IBS always includes the following components, 1). security system, 2). alarm system, 3). access control system, 4). audio/video system 5). lift system, 6). HVAC system, 7). power management system, 8). lighting system. In the past, these components were all standalone system and had to communicate through a complex wire technique with high cost until recently. The new building automation protocol adopts the open and distributed architecture with an uni-field bus that even the power line can be used as the communication field bus. Under this structure, we group the field devices to several basic utilities unit that organize the components in IBS through cooperation among these basic utilities. According to these features of IBS, a holonic SCADA (HSCADA) can be applied to it. In HSCADA, a holon represents an autonomy and cooperation building block. There two types of holon, namely, software holon and firmware holon which are separated into the software layer and firmware layer and an integrated control kernel, namely supervisory request oriented control kernel (SROCK). In IBS, each component can be composed by software holon meanwhile the basic utilities and hardware device control can be composed by firmware holon. Each holon can implement the needed intelligence into itself. A group of holons can handle all behaviors in the IBS. In HSCADA, the SROCK is an integrated control unit which supports the capabilities as follows. 1). holon integration, 2). user request editor, 3). user request process, 4). error recovery. The first one increases the flexibility, scalability of systems that controlled by SROCK whereas applied in Internet. The second one supports a user-friendly control interface between IBS and occupancy such as macro request, and control command automatically retrieving. These allow the occupancy using the service more efficiently. Finally, when the devices in IBS break down, the SROCK can do error recovery that makes it a reliable system. The error can’t break down and effects the system.

Hierarchical shop floor control framework probably is the most popular control schema applied in industry. However, due to the inflexible of the control schema, such as the lack of autonomous capability about the individual control construct or the rigid relations existed among the control constructs, hierarchical framework has faced certain challenges from the current manufacturing environments. The concepts of holonic manufacturing systems (HMS) have addressed part of the problems. In this research, a holon identification process based on a business modeling method, ARIS, has been proposed. Three stages have been included in the process. One is to identify the individual holon constructs from an ARIS model according the characters of HMS. The relations among the identified holons were built in the second stage. Finally, a method to construct the holarchy, or the structure of the identified holons was developed. The proposed method has been implemented in a CIM system.

The competitive environment for the manufacturing industry has changed rapidly. Product life cycle getting short, production schedule getting tight, and customer demands getting diverse. Facing such challenging environment, the manufacturing enterprises have to improve the agility or responseness of their manufacturing system significantly for their survival in the market. Manufacturing agility or responseness is exactly what “Agile Manufacturing” is aiming to reach. However, to reach the ideal of Agile manufacturing is totally by no mean to be a trivial task. A manufacturing execution control system (MECS), which is robust, configurable, easy to construct and fit to real practice in industry is required. Here in this research, we only focus on the manufacturing execution control of a manufacturing cell rather than the whole manufacturing plant. Nevertheless, the concept of holonic architecture was adopted to model the whole manufacturing system, including manufacturing cell and its subsidiaries. Also, multi-agent system architecture was employed to design a manufacturing cell execution control system which intend to be robust, reconfigurable, easy to construct and fit to the real practice in industry. The designed system is expected to be able to effectively and flexibly integrate the whole system horizontally and vertically so as to facilitate the ideal of agile manufacturing. In this research, the whole operation in the manufacturing cell execution control was divided into two layers: managerial decision layer and operational control layer. The operation in the managerial decision layer was modeled by event-driven process chain (EPC), while the operation in the operational control layer was modeled by MED-CPN, which is Modularized Event Driven Color Petri-Net proposed in this research. Based on EPC and MED-CPN, an agile manufacturing cell execution control system was designed for a generic agile manufacturing cell (GAMC), which was also proposed in this research for capable of modeling almost any kind of agile manufacturing cell.

Virtual enterprise and concurrent engineering are two of the most promising business strategies to address global competition. By unifying the concepts of virtual enterprise and concurrent engineering, allied concurrent engineering aims to integrate the engineering activities and resources from different enterprises through enterprise alliances to quickly respond to customer expectations. The essence of allied concurrent engineering is a distributed and collaborative engineering process, where people in different disciplines, from different enterprises cooperate to design a product and develop related processes through remote coordination, communication, and control. The objective of this research is to design a holonic system framework for engineering data management to support allied concurrent engineering by providing functions for Product and Process Item Definition and Management, Project Planning and Management, Activity Work Area Service, Information Service and Library Management. The framework is designed based on the concepts of holonic systems to reflect the dynamic organized, distributed, cooperative, and heterogeneous natures of allied concurrent engineering processes.

A Holonic Manufacturing System (HMS), which is designed to realize the agile manufacturing enterprise, must be able to integrate the entire range of manufacturing activities from market demands, design, modeling, production, through delivery. These entire activities are implemented by several distributed sites. In order to effectively integrate these distributed sites, in this approach, we adopt distributed object, mobile object, and object web technologies as well as the holon and holarchy concepts derived from studying social organizations and living organisms to develop a Holonic Information Coordination System (HICS). This approach is started with system analysis by collecting domain requirements and analyzing domain knowledge. Then HMS Holarchy is designed by the process of constructing abstract object model based on domain knowledge; partitioning application domain into functional Holons; identifying generic parts among functional Holons; and finally designing functional Holons based on the Generic Holon. Generic Holon will adopts the technologies of distributed object-oriented approach with CORBA infrastructure, N-tier client/server architecture, knowledge base and data warehousing to achieve the abilities of reconfiguration, error recovery and security certification. In order to verify the applicability of Generic Holon, this approach develops Communication Holon by inheriting Generic Holon and using Communication Holon to establish HICS. Thus, the Communication Holon has the basic holonic attributes, such as intelligence, autonomy, and cooperation. Further, Communication Holon can handle information sharing, coordination among enterprises and process data object by different data format. Due to the security and error diagnosis mechanism of Generic Holon, HICS becomes more reliable than legacy system. Further, HCIS is designed to meet the future requirements of supply chain information integration for virtual enterprises

Abstract There are some disadvantages in traditional manufacturing systems using centralized control architecture, such as inflexibility, lack of scalability and hard to fit in distributed system layout. It''s a challenging task to build a new generation for manufacturing control paradigm with promising merits that can achieve real time response to environment changes and resolve resource conflicts in a distributed manner. This research addresses the Holonic manufacturing system that has shown its potentials in recent researches. The main focuses of the researches are as follows: (i) to present a methodology for modeling holonic manufacturing systems; and (ii) to design a generic negotiation mechanism among system agents. We present a two-phase object-oriented modeling methodology for building holonic manufacturing system using distributed computing. We also present a coordination mechanism based on negotiation decision function which is characterized of multi-parties, multi-issues, and single-encounter. We prove the convergences of the proposed negotiation mechanism, and apply it in a job shop manufacturing system in which utilization-dependent tactics and dynamic-weight-tuning function are utilized. Finally we present a Swarm-based simulation model using the proposed negotiation mechanism to demonstrate the efficiency of holonic manufacturing systems and the proposed negotiation mechanism.

Scheduling has been one of the major tasks in operational management. It has direct impact on the efficiency and effectiveness of production operations. In order to obtain a better production schedule to improve the performance of daily production operations and to increase the competition of the business organization, numerous academic researchers and industrial participants have devoted tremendous amount of effort in developing scheduling algorithms. Due to the combinatorial characteristics, the scheduling problems are classified as NP-hard. Therefore, various heuristics, such as genetic algorithm, simulated annealing, and others, have been developed and tested to show the strength of obtaining closed-to-optimal solutions. Besides, it is quite common that new orders and/or rush orders may arrive after the master production schedule has been determined. The need of scheduling new arrivals creates the problem of ‘re-scheduling’. Scheduling and re-scheduling become typical hurdles for production planning personnel. It is very common, when rescheduling is needed, to reschedule all the pending orders. Such rescheduling method results in building a new mater production schedule every time when a new order is received. It is very typical that the production planning department holds a large number of pending orders. To reschedule all the pending orders increases the responding time to confirm a new order and to alter scheduled activities, including material planning, human resource planning, and etc. In the modern industrial environment, longer responding time means less profit. Therefore, how to shorten the responding time of rush orders, i.e., how to reschedule rush order in less time, has become one important issue in production planning domain. This thesis develops a two-stage methodology to perform scheduling and rescheduling activities. The first stage determines the master production schedule. At the second stage, a partial rescheduling algorithm is developed to shorten the responding time to newly arrived rush orders. The partial rescheduling algorithm only reschedule the first several orders and the rush order and leaves the sequence of the rest orders unchanged. The problem is formulated as a nonlinear problem, which encompasses production costs, material and finished products storage costs, communication cost for changing delivery time, emergent procurement cost and penalty cost for late delivery. At both stages, genetic algorithm is used to solve scheduling and re-scheduling problems. The results show that the partial rescheduling methodology has advantages in terms of responding times and costs. It is also found that the numbers of orders to be rescheduled are between 5 and 7. Statistical tests show that capacity utilization, material storage cost, and communication cost have significant effect on rescheduling.

In modern industry, companies have been facing changeable market demands and limited resources. How to effectively arrange production activities based upon various objectives has become one of the most important challenges. This research proposes a holonic manufacturing system approach to scheduling and dispatching jobs on unrelated parallel machines. The proposed system is divided into two stages. At the first stage, grey relationship analysis is used to establish the sequence of jobs to be produced to cop multiple criteria, such as makespan, tardiness, and the number of late jobs. An HMS architecture is developed to dynamically dispatch jobs on 3 unrelated machines. This research differs from the typical scheduling system is that the former takes care multiple objectives, both qualitative and quantitative ones, the latter mainly considers single operational criteria. It also differs from autonomous systems in such a way that the proposed system considers both local and global objectives, the autonomous systems generally use negotiation schemes and focus on local objectives. In comparing to traditional dispatching rules, such as CR, EDD, and SPT, the results from this research showed the proposed system can perform better in terms of balanced performances.

Automatic Storage and Retrieval System (AS/RS) is a three-dimensional warehouse system which can automatically store incoming material and retrieve stored parts with no direct human handling. A typical AS/RS configuration includes several aisles with storage racks on both sides of each and with one storage/retrieval machine (S/R machine), or called crane, in each aisle and several material transportation systems in different floors for connecting the material flow between input/output ports in each floor and the S/R machine in each aisle. The AS/RS to be studied and controlled in this research is basically an AS/RS of typical configuration, but with multiple cranes allowable in each aisle and multiple cars in each material transportation system. The aim of this research is thus to develop a generic execution control system for such a material flow integrated AS/RS with aisles of multi-cranes. In this execution control system, the AS/RS system configuration can be flexibly defined, and a wide variation in the number of floors, aisles, cranes and transportation cars included can be handled by the generic control system, such that the controllable AS/RS can own the feature of high agility, reconfigurability and extendibility. Also, an agent-based holonic manufacturing architecture was adopted for designing the execution control system, in which each agent was modeled with EPC (Event-Driven Process Chain) for the upper level decision & planning operation and with a modified Colored Petri-Nets for the lower level equipment real time control operation.

Full textAbstract:
Interfaith dialogue is no luxury for Christians living in a pluralistic~ effervescent world of intenningling, multi-religious realities. Many Christians take seriously their responsibility towards interfaith dialogue. However, different Christians understand this responsibility in different ways, which often leads to acrimonious accusations of
unchristian dialogical approaches. The question is whether there is any means of ordering and assessing the Christian responsibility towards other religions in a mutually uplifting and increasingly holistic way? Ken Wilber provides an integral, or All-Quadrant, All-Level hermeneutics that may assist us with an answer. All holonswhich means everything in the "Kosmos" - emerge or arise in holarchical fashion. On one level, it is a whole, on the next transcendent level it is a part of the whole. This
process is infinite and is only ever released in One Taste/salvation/Nirvana/the Kingdom of God, or simply unqualifiable Suchness. Wilber provides an integrated methodology for understanding the process by which holons find their release in One Taste. The holon of Christian responsibility towards interfaith dialogue also emerges
through discreet, recognizable stages. Each stage is integrated into the next higher level. The lower levels are more fundamental since they exist as a part of the higher levels. However, the higher levels are more significant, since they have an increased capacity to explore aspects of dialogue previously hidden. The levels we explore are the mythic rational, the rational and the centauric. 'lbese levels emerge through four
interrelated dimensions or Quadrants: the Upper Left or spiritual/faith dimension of the person entering into dialogue, the Upper Right Quadrant or theology of dialogue that emerges, the Lower Left or communal and interpretive realm, and Lower Right which covers the social organizational patterns with which the person in dialogue chooses to associate him or herself. We define responsibility in tenns of these four
Quadrants: The response or theology (UR) of the person is dependent upon her response-ability, or interior faith development (UL), which is informed by the worldview (LL) of her faith community to whom she feels responsible, with the sociological patterns of her community (LR), to some extent, offers clues as to her stage of development.Religious Studies and Arabic
