Travaux de thèse d'Omar BOUGACHA : "Contribution to post-prognostic decisions: new framework based on prognosis-decision interactions"

Abstract : With the emergence of prognostics and health management (PHM) methodology, companies are trying to fully exploit the data sources they have to build models for their assets and predict their future behavior. Therefore, the decision-making process is no longer based on only historical and actual data, but it integrates future information. On one hand, decisions in the PHM context are based on future information. On the other hand, the estimation of future conditions of the systems requires a knowledge on its future loads and usage (i.e. future decisions). Several works have studied the decision-making process in the PHM context. However, none of these works have addressed the prognostic-decision interdependency. Moreover, most of the post-prognostic decision-making works present several omissions: 1) How to emphasize the relationship between the prognostic and decision-making modules? 2) How often should the PHM process be launched? 3) How long ahead should the decision-making module plan? 4) How to better/fully use prognostic information in the decision process? 5) How to clarify the applicability of the PHM framework? 6) How to make the PHM framework robust to the system's conditions changes? These
questions are addressed along this thesis  [...]
