Abstract:

This thesis describes experiments designed to measure the effect of collaborative communication on task performance of a multiagent system. A discrete event simulation was developed to model a multi-agent system completing a task to find and collect food resources, with the ability to substitute various communication and coordination methods. Experiments were conducted to find the effects of the various communication methods on completion of the task to find and harvest the food resources. Results show that communication decreases the time required to complete the task. However, all commun

Doctor of Philosophy<br>Department of Computing and Information Sciences<br>Scott A. DeLoach<br>Organization-based Multiagent Systems (OMAS) have been viewed as an effective paradigm for addressing the design challenges posed by today’s complex systems. In those systems, the organizational perspective is the main abstraction, which provides a clear separation between agents and systems, allowing a reduction in the complexity of the overall system. To ease the development of OMAS, several methodologies have been proposed. Unfortunately, those methodologies typically require the designer to hand

Abstract:

Multi-agent systems are a new computational approach for solving real world, dynamic and open system problems. Problems are conceptualized as a collection of decentralised autonomous agents that collaborate to reach the overall solution. Because of the agents autonomy, their limited rationality, and the distributed nature of most real world problems, the key issue in multi-agent system research is how to model interactions between agents. Negotiation models have emerged as suitable candidates to solve this interaction problem due to their decentralised nature, emphasis on mutual selection of a

Abstract:

Rational agent behaviour is frequently achieved through the use of plans, particularly within the widely used BDI (Belief-Desire-Intention) model for intelligent agents. As a consequence, preventing or handling failure of planned activity is a vital component in building robust multiagent systems; this is especially true in realistic environments, where unpredictable exogenous change during plan execution may threaten intended activities. Although reactive approaches can be employed to respond to activity failure through replanning or plan-repair, failure may have debilitative effects that act

Recently, the design and development of multiagent systems (MASs) has become increasingly concerned with the recognition that they will be used in a dynamic and open environment. In such environments, it is a very difficult and complicated task to anticipate all possible runtime situations at design time. Therefore, in order to respond to changes in this environment it is necessary to allow the system to provide dynamic responses at runtime. This thesis is concerned with one particular aspect of such responses. Our novel contribution is that we explicitly identify clarify and address the probl

Abstract:

Nesta tese, propõe-se integrar, de modo sistemático, modelos organizacionais para prover interoperabilidade organizacional em sistemas multiagentes abertos. A interoperabilidade organizacional consiste em permitir que, em uma mesma organização de agentes, coexistam agentes desenvolvidos a partir de modelos organizacionais distintos. Para realizar tal intuito, aplica-se uma abordagem baseada em técnicas da Engenharia Dirigida por Modelos. A abordagem proposta divide-se em três etapas principais: (1) representar a estrutura conceitual de modelos organizacionais através de metamodelos; (2) identi

Abstract:

A representação do conhecimento de maneira mais fiel possível à realidade é uma meta histórica e não resolvida até o momento na área da Inteligência Artificial. Problemas são resolvidos e decisões são tomadas levando-se em conta diversos tipos de conhecimentos, os quais muitos são tendenciosos, inexatos, ambíguos ou ainda incompletos. A fim de tentar emular a capacidade de representação do conhecimento humano, levando-se em conta as diversas dificuldades inerentes, tem-se construído sistemas computacionais que armazenam o conhecimento das mais diversas formas. Dentro deste contexto, este traba

Abstract:

La thèse porte sur le contrôle des systèmes de systèmes (SdS) et, sur la manière de construire des SdS adaptables et fiables. Ce travail fait partie du laboratoire d’excellence Labex MS2T sur le développement des SdS technologiques. Les SdS sont des systèmes complexes constitués de plusieurs systèmes indépendants qui fonctionnent ensemble pour atteindre un objectif commun. L’ingénierie des SdS est une approche qui se concentre sur la manière de construire et de concevoir des SdS fiables capables de s’adapter à l’environnement dynamique dans lequel ils évoluent. Compte tenu de l’importance du c

Abstract:

The thesis presents and evaluates the application of the paradigm of agents to the management of the urban wastewater system. The system is conceptualised as a multi-agent system from the development of the models of agents and communication paths. In the development, it has become obvious that coordination (of volumes and pollutant loads) between all the wastewater treatment inputs and the available capacity of the treatment is a key point in the system’s performance. To consider this factor, a coordinating agent is defined. This agent executes the coordination of inputs and the prioritisati

Abstract:

Cette thèse s'inscrit dans le contexte de l'allocation en ligne multi-agents multi-tâches, dont le but est de coordonner efficacement un ensemble d'agents (ressources) afin de distribuer des tâches entre eux. À titre d'exemple d'application, nous pouvons citer les cas où des clients font des requêtes à un fournisseur de services qui cherchera la meilleure répartition des tâches parmi son ensemble d'agents : des taxis répondant à la demande des clients ou des robots assurant la distribution de colis.Contrairement au cadre hors ligne, qui suppose une connaissance totale du problème d'allocation

Abstract:

Cette thèse s’intéresse à la question de l’évaluation des Systèmes Multi-Agents (SMA). Les caractéristiques propres que possèdent ces derniers, notamment en termes d’autonomie, de distribution, de dynamique et de socialité, ont grandement contribué à l’élargissement de leurs champs d’application, mais en contrepartie, elles ont rendu leur analyse plus ardue. Ainsi, les méthodes d’évaluation dans les systèmes informatiques classiques s’avèrent insuffisantes à analyser les SMA, étant donné qu’elles ne tiennent pas compte de leurs spécificités. L’objectif de cette thèse consiste donc à proposer u

La modélisation de la dynamique des piétons, des cyclistes et des conducteurs de véhicules est d'un grand intérêt théorique et pratique. Au cours des deux dernières décennies, la Recherche dans un large éventail de domaines tels que l'infographie, la physique, la robotique, les sciences sociales, la sécurité et les systèmes de formation a créé des simulations impliquant des individus de type hétérogènes. Deux grands types de simulation d'individus dans un univers virtuel peuvent généralement être distingués selon qu'elles cherchent à atteindre : un haut niveau de réalisme de comportement (simu

Abstract:

La coordinació i assignació de tasques en entorns distribuïts ha estat un punt important de la recerca en els últims anys i aquests temes són el cor dels sistemes multi-agent. Els agents en aquests sistemes necessiten cooperar i considerar els altres agents en les seves accions i decisions. A més a més, els agents han de coordinar-se ells mateixos per complir tasques complexes que necessiten més d'un agent per ser complerta. Aquestes tasques poden ser tan complexes que els agents poden no saber la ubicació de les tasques o el temps que resta abans de que les tasques quedin obsoletes. Els agent

Abstract:

Nous prenons le point de vue d'un agent sur le point d'entrer dans une organisation multi-agent, où il aura à choisir parmi plusieurs rôles disponibles. Notre objectif est de donner à cet agent les moyens d'évaluer avant d'entrer dans une organisation les implications que cette action aura sur ses capacités de satisfaire les désirs de son utilisateur. Quand il entre dans une organisation, un agent devient le sujet de plusieurs contraintes imposées par des entités externes (d'autres agents, l'organisation même, la société). Comme le montre cette thèse, l'autonomie sociale de décision est une ca

Abstract:

L'observation des systèmes complexes artificiels à grande échelle est difficile en raison de leur dimension et de leur ouverture. Cette thèse propose le modèle SMA-R (Système Multi-Agent Récursif) basé sur la récursivité pour l'observation multi-niveau des systèmes complexes artificiels. À partir d'un Système Multi-Agent donné, ce modèle est capable de construire une représentation abstraite multi-niveau. Le modèle d'agent récursif proposé possède un module contenant les connaissances, les capacités et le contexte de récursivité; un module pour observer les changements; deux mécanismes pour co
