Abstract:
The goal of this thesis is twofold: first, we want to present the distributed belief accommodation and revision model for multi-agent systems that has been developed and, second, we wish to show its applicability to an appropriate domain. The Distributed Belief Accommodation & Revision model, called DeBAteR model, was developed for co-operative heterogeneous multi-agent systems used to model inherently dynamic distributed problems. In these systems, although the agents are able to detect changes both in the environment and in the problem specifications, each agent has only a partial view of th

Abstract:
This work concerns multi-agents systems for the management of a corporate semantic web based on an ontology. It was carried out in the context of the European project CoMMA focusing on two application scenarios: support technology monitoring activities and assist the integration of a new employee to the organisation. Three aspects were essentially developed in this work: the design of a multi-agents architecture supporting both scenarios, and the organisational top-down approach followed to identify the societies, the roles and the interactions of agents.

In such problems, a set of resources must be allocated to a set of agents, according to their own preferences.

Such problems are usually solved by means of centralized techniques, where an omniscient entity determines how to optimally allocate resources.

Abstract:
Les systèmes multi-agents sont constitués d'entités autonomes qui interagissent avec leur environnement pour résoudre un objectif collectif. Si l'on souhaite modéliser des systèmes contenant des millions d'agents, une puissance de calcul et de stockage importante devient nécessaire. Pour atteindre de telles simulations large échelle, distribuer le simulateur sur un réseau de machines est nécessaire, mais il faut prendre en compte quelques aspects. Le premier aspect se concentre sur deux types de répartition de la charge de calcul : la première basée sur l'environnement, la deuxième basée sur l

Abstract:
Cette thèse présente le modèle d'un mécanisme de raisonnement social fondé sur la théorie de la dépendance. Ce modèle permet à un agent de raisonner sur autrui et plus particulièrement de calculer ses relations et situations de dépendance. Un agent est dépendant d'un autre si celui-ci peut l'aider/l'empêcher d'atteindre un de ses buts. Nous considérons notre mécanisme de raisonnement social comme un composant essentiel pour la conception d'agents artificiels réellement autonomes, évoluant dans un univers multi-agents ouvert. La notion d'ouverture désigne la capacité d'ajouter ou de retirer dyn

Abstract:
Les systèmes multi-agents sont des systèmes dynamiques composés par plusieurs éléments qui interagissent entre eux. Ces éléments sont appelés agents. Un agent est un système dynamique caractérisé par deux propriétés. La première est que les agents sont autonomes— c’est-à-dire qu’ils ne sont pas dirigés par l’environnement extérieur et ils peuvent évoluer selon un comportement auto-organisé. La seconde est que les agents sont capables de communiquer entre eux pour accomplir des tâches complexes, telles que la coopération, la coordination et la résolution de conflits.

Abstract:
Multi-agent systems have been used in a wide range of applications from computer-based simulations and mobile robots to agent-oriented programming and intelligent systems in real environments. However, the largest environment in which software agents can interact is, without any doubt, the World Wide Web and ever since its birth agents have been used in various applications such as search engines, e-commerce, and most recently the semantic web. However, agents have yet to be used on the Web in a way that leverages the full power of artificial intelligence and multi-agent systems, which have th

Abstract:
Les Systèmes Multi-Agents (SMA) ont gagné en popularité en raison de leur vaste gamme d'applications. Les SMA sont utilisés pour atteindre des objectifs complexes qui ne pourraient être atteints par un seul agent. La communication et l'échange d'informations entre les agents d'un SMA sont essentiels pour contrôler son comportement coopératif. Les agents partagent leurs informations avec leurs voisins pour atteindre un objectif commun, ils n'ont donc pas besoin d'unité centrale de surveillance. Cependant, la communication entre les agents est soumise à diverses contraintes pratiques. Ces contra

Abstract:
Die mobile Robotik stellt ein sehr junges und komplexes Forschungsfelder unserer Zeit dar. Innerhalb der letzten Jahrzehnte wurde es Robotern möglich, sich innerhalb ihrer Umgebung zu bewegen, zu navigieren und mit ihrer Umwelt zu interagieren. Aufgrund der Tatsache, dass die Welt von Unsicherheit geprägt ist und ein Roboter immer nur partielle Information über sie erhalten kann, wurden probabilistische Navigationsverfahren entwickelt, mit denen sich Roboter lokalisieren und Objekte ihrer Umgebung modellieren können. Weiterhin wurden in letzter Zeit Verfahren untersucht, die die koo

Abstract:
In this thesis, we explore the topic of designing an architecture and processing algorithms for a multi-agent system, where agents need to address potential unexpected events in the environment, operating under soft real-time constraints. We first develop a classification of unexpected events into Opportunities, Barriers and Potential Causes of Failure, and outline the interaction required to support the allocation of tasks for these events. We then propose a hybrid architecture to provide for agent autonomy in the system, employing a central coordinating agent. Certain agents in the
