In recent years, Physics Informed Neural Networks (PINNs) have shown promising results in Prognostics and Health Management (PHM). A PINN relies on the physical bias inside a Neural Network (NN) to predict engineering equipment’s Remaining Useful Life (RUL). This physical integration can assume three forms: observational bias, inductive bias, or learning bias. This doctoral thesis will focus on inductive bias by creating physical layers inside an NN. This research aims to create a Convolutional Neural Network (CNN) with a modular structure composed of different “lego” layers. Each layer will have a different structure and goal. We will also study how the CNN structure can be modified and optimized according to the case study.
