TOWARDS A SELF-ADAPTIVE MULTI-AGENT APPROACH FOR ENHANCING THE QUALITY OF SERVICE PROVIDED BY OPEN INFORMATION SYSTEMS

摘要

Current information systems are plunged into highly dynamical environments which produce occurrences of unpredictable situations. This dynamics combined with the inherent geographical and functional distribution of such systems, make usual adaptation techniques which are global or dependent of the intended global function realised by the system, unsuitable. Our contribution concerns a partial instantiation of a local adaptation method, based on adaptive multi-agent systems, to manage the QoS of information systems. This management is done according to two points of view addressed in an integrate way: a quantitative one and a qualitative one. First obtained results, showing the benefits of cooperation to the adaptation of such systems, are then discussed.
