Un ravageur virtuel pour expérimenter des méthodes réelles de lutte intégrée : l'utilisation de modèle à base d'agents pour explorer les comportement…
2015
Lobesia botrana is a microlepidoptera moth a common pest in European vineyards. Larvaes cause damages both by eating plant reproductive organs and indirectly by promoting the infection of grape berries by saprophytic pathogens.Since 1999, the Banyuls and Albères Agricultural Development Group (GDA) keeps track of infestations by L. botrana on control plots. Moreover, since 2012, thanks to the ANR TERVICLIM, the of Banyuls AOC region is covered by a network of temperature recording stations.This year, the GDA launches an IPM (Integreted Pest Management) plan based on mating disruption that requires the involvement of vine-growers. The aim of this paper is two-fold: the calibrating an agent-b…
Semantically enriched informed environment for multi-agent simulation : application to simulation in 3D virtual environment
2014
This thesis focuses on multi-agent simulation applied to the simulation of individuals in virtual 3D buildings. To do this, our work suggests to capitalize on the experience gained in the field of semantic web ontologies and inference engines to facilitate the design and development of intelligent behavior for agents operating in virtual worlds. The goal is to provide to agents a generic approach to managing their representation of the world and reason about this representation. For this, the central problem is based on the definition of a decidable ontology modeling all of the knowledge contained in the virtual 3D environment to enrich semantically the environment of a multi-agent simulati…
Qualifying Building Information Models with Multi-Agent System
2011
6 pages; International audience; This paper presents a new approach combining the 3D elements composing the environment of mobile agents with semantic descriptors from building information models. Our proposal is based on the IFC standard which is used in the field of Civil Engineering to build digital models of buildings during the design phase. The semantic of IFC objects composing the 3D environment is used to select and set up 3D objects and elements of simulation scenarios. The result of this process dynamically generates the input files to the JaSIM environment that performs the simulation.
SEMANTIC MANAGEMENT OF INTELLIGENT MULTI-AGENTS SYSTEMS IN A 3D ENVIRONMENT

8 pages; International audience; This paper presents a new approach combining the 3D elements composing the environment of mobile agents with semantic descriptors from Building Information Models. Our proposal is based on the IFC standard, which is used in the field of Civil Engineering to build digital models of buildings during the design phase. The semantic of IFC objects composing the 3D environment is used to select and set up 3D objects and elements of simulation scenarios.

These files deserve the representation of the virtual environment in which the simulation is …

Toward a Society of Robots: Behavior, Misbehavior, and Security
2010
In this article, we consider how a very large numbers of robots, differing in their bodies, sensing, and intelligence, may be made to coexist, communicate, and compete fairly toward achieving their individual goals, i.e., to build a society of robots. We discuss some characteristics that the rules defining acceptable social behaviors should possess. We consider threats that may be posed to such a society by the misbehaviors of some of its members, either due to faults or malice, and the possibility to detect and isolate them through cooperation of peers. The article presents examples of motion control protocols, for arbitrarily large groups of heterogeneous robots. We discuss intrusion dete…
Multi-Platform Agent Systems with Dynamic Reputation Policy Management
2011
Open, distributed multi-platform agent systems require new management approaches for resources and data secure access. In this paper a Jade-S based multi-platform agent system implementing dynamic reputation policy management is proposed. The implemented extension deals with biometrics, X-Security, DES cryptography and agent reputation. With more details, the proposed reputation management system helps to assess the agent's behavior and reliability, in order to select trusted agents. This is made possible by the knowledge that agents are able to acquire, over time, and that allows them to choose the best solution using own intelligence in total autonomy.
Marrakair: une simulation participative pour observer les émissions atmosphériques du trafic routier en milieu urbain
2017
National audience; D’après l’Organisation Mondiale de la Santé (OMS), la pollution de l’air est le principal risque environnemental pour la santé dans le monde 1 (OMS, 2013). Àl’échelle locale, la pollution atmosphérique agit sur quelques kilomètres et se manifeste à proximité des sources de pollution comme la proximité aux sites industriels. En milieu urbain, le premier contributeur aux émissions de NOx, CO, ou PM10 dans l’atmosphère est le trafic routier (CITEPA, 2014). La pollution atmosphérique automobile (PAA) se caractérise en effet par l’émission de composés toxiques et cancérigènes directement émis par les moteurs. L’intensité des émissions est à relier au nombre de véhicules présen…
Contribution of Multi-Agent Systems and Fuzzy logic to support tutors in Learning Communities
2016
The growing importance of online training has put emphasis on the role of remote tutoring. A whole new area of research, dedicated to environment for human learning (EHL), is emerging. We are concerned with this field. More specifically, we will focus on the monitoring of learners.The instrumentation and observation of learners activities by exploiting interaction traces in the EHL and the development of indicators can help tutors to monitor activities of learners and support them in their collaborative learning process. Indeed, in a learning situation, the teacher needs to observe the behavior of learners in order to build an idea about their involvement, preferences and learning styles so…
Simulation d'un transport spontané non régulé, par un système multi-agents
2009
International audience; Les Systèmes Multi-Agents constituent aujourd'hui une approche prisée par les géographes pour modéliser et simuler des systèmes complexes par une approche individu centrée. Nous proposons de simuler un transport spontané non régulé (donc peu contraint), et très dynamique (type taxi-brousse) basé sur deux agents : des taxis et des villageois. Cet article résumé est issu d'un travail collectif de plusieurs chercheurs à la formation MAPS** (Modélisation multi-agents appliquée aux phénomènes spatialisés) de juin 2009, suivi d'un développement particulier réalisé à l'UMR ESPACE*.
