Multi-objective adjustment of remaining useful life predictions based on reinforcement learningKozjek, Dominik (Avtor) Malus, Andreja (Avtor) Vrabič, Rok (Avtor) predictive maintainanceremaining useful lifereinforcement learningEffective tracking of degradation in machine tools or vehicle, ship, and aircraft engines is key to ensure their high utilization, effective maintenance, and safety. Data from the built-in sensors can be used to build models that accurately predict the remaining useful life (RUL) of the observed system. However, existing approaches often lack the ability to incorporate domain-specific knowledge in form of degradation models. This paper proposes a reinforcement-learning based approach for encoding the degradation model used for multi-objective adjustment of RUL predictions. The approach is demonstrated with a case of RUL prediction for aircraft engines.20202020-09-29 09:16:54Članek v reviji121028sl
