Contribution à la robustesse dans les CSPs distribués par réplication locale

Abstract : We aim to ensure a DisCSP resolution in presence of failed agents. Methods handling fault tolerance in MASs aim to ensure the continuity of the system operation. But, none of these methods are applied to solve a DisCSP. The failure of an agent generates the loss of a part of the DisCSP providing wrong results. Therefore, to obtain expected results, it is necessary to ensure the resolution of the failed agent local CSP.We propose to replicate the local CSPs of the failed agents within active agents. This replication allows local CSP resolution of the failed agent by another agent. The resolution is done by merging the replicates of failed agents CSPs with the CSPs of other agents. This technique conserve the initial DisCSP modeling. The proposed replicates distribution algorithm ensures that the CSPs of failed agents are not replicated within the same agent. In this way, the problem keeps its distributed aspect.
