Les systèmes de classeurs

Learning Classifier Systems (LCSs) are rule-based systems that automatically build their ruleset. Initially, LCSs were dedicated to the modelling of the emergence of cognitive abilities thanks to adaptive mechanisms, particularly evolutionary processes. After a renewal of the field more focused on learning, LCSs have been reconsidered as sequential decision problem solving systems endowed with ...

Patterns de coopération de systèmes d'information

Cooperation of heterogeneous legacy information systems in organizations is a reality, offering to users a unified access to heterogeneous and distributed information. Our goal is to capitalize design knowledge involved in cooperative application development and to define cooperation patterns adapted from Fowler’s analysis patterns. These patterns, derived from ACSIS cooperative architecture, a...

Techniques de localisation et de résumé des données dans les systèmes P2P. (Data Localization and Summarization Techniques in P2P Systems)

The goal of this thesis is to contribute to the development of data localization and summarization techniques in P2P environments. At the application layer, we focus on exploiting the semantics that can be captured from the shared data. These semantics can improve the search efficiency, and allow for more query facilities. To this end, we introduce a novel data indexing technique into P2P syste...

Environnement G-DEVS/HLA pour la simulation distribuée de systèmes de production multiprocessus

This paper presents a simulation environment for manufacturing systems integrating control processes and operational processes. From the operational processes specification according to the JIS Z 8206 norm and from the control processes as Workflows standards, distributed G-DEVS models are generated. At first, the transformation of a process in G-DEVS models is described. Then, the implementati...
