Subject Ph. D.

IFPEN aims to become a key player in the triple energy, ecological and digital transition by offering differentiating technological solutions in response to the societal and industrial challenges of energy and climate. The implementation of new methodological approaches that combine data science and experimentation is among the solutions under study to accelerate progress and reduce R&D costs. Learning algorithms based on time series data, which constitute most generated data, are currently gaining momentum in the literature, whether supervised or unsupervised (ARIMA, LSTM⬦). The field of Prognostics and Health Management (PHM) is of particular interest. It is a discipline that focuses on the degradation mechanisms of systems to estimate their health status, anticipate failures, and optimize maintenance. For instance, on a pilot plant, it is very challenging to obtain data during operational problems, which are becoming more frequent due to the high variability of loads to process and operational conditions to explore. This thesis aims to overcome these challenges by exploring data-driven methodologies. The choice of this approach is justified by the extensive diversity of data available at IFPEN. Additionally, new experimental trials may be conducted as a complementary measure.
