Genetically optimized prediction of remaining useful life

چکیده
The application of remaining useful life (RUL) prediction is very important in terms energy optimization, cost-effectiveness, and risk mitigation. existing RUL algorithms mostly constitute deep learning frameworks. In this paper, we implement LSTM GRU models compare the obtained results with a proposed genetically trained neural network. current solely depend on ADAM SGD for optimization learning. Although have worked well these optimizers, even little uncertainties prognostics can result huge losses. We hope to improve consistency predictions by adding another layer using Genetic Algorithms. hyper-parameters – rate batch size are optimized beyond manual capacity. These architecture tested NASA Turbofan Jet Engine dataset. predict given autonomously provide superior results.

Bayesian Approach for Remaining Useful Life Prediction
Prediction of the remaining useful life (RUL) of critical components is a non-trivial task for industrial applications. RUL can differ for similar components operating under the same conditions. Working with such problem, one needs to contend with many uncertainty sources such as system, model and sensory noise. To do that, proposed models should include such uncertainties and represent the bel...
متن کاملEnsemble of optimized echo state networks for remaining useful life prediction
The use of Echo State Networks (ESNs) for the prediction of the Remaining Useful Life (RUL) of industrial components, i.e. the time left before the equipment will stop fulfilling its functions, is attractive because of their capability of handling the system dynamic behavior, the measurement noise, and the stochasticity of the degradation process. In particular, in this paper we originally reso...
متن کاملA Study on Remaining Useful Life Prediction for Prognostic Applications
We consider the prediction algorithm and performance evaluation for prognostics and health management (PHM) problems, especially the prediction of remaining useful life (RUL) for the milling machine cutter and lithium‐ion battery. We modeled battery as a voltage source and internal resisters. By analyzing voltage change trend during discharge, we made the prediction of battery remain discharge ...
متن کاملA Similarity-based Prognostics Approach for Remaining Useful Life Prediction
Physics-based and data-driven models are the two major prognostic approaches in the literature with their own advantages and disadvantages. This paper presents a similarity-based data-driven prognostic methodology and efficiency analysis study on remaining useful life estimation results. A similarity-based prognostic model is modified to employ the most similar training samples for RUL estimati...
متن کاملRemaining Useful Life Estimation In the Presence of Given Shocks
In a system, prediction of remaining useful lifetime (RUL) of servicing before reaching to a specified breakdown threshold is a very important practical issue, and research in this field is still regarded as an appreciated research gap. Operational environment of an equipment is not constant and changes regarding to stresses and shocks. These random environmental factors accelerate system deter...
