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...

The primary objective of the project was the development of criteria to define the end-of– life condition of pavements. These criteria could then be used in pavement performance modelling to obtain a more robust measure of remaining life. Another objective was the generation of a new model for maintenance costs. This could then be combined with the existing models for roughness and rutting to d...

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 learni...

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...

In this study, a real and significant industrial problem in a steam power plant was investigated. Reheater tubes in boilers are under the creep and the fireside corrosion mechanism that cause some of them to fail. Since the estimation of probability of failure (PoF) and remaining life (RL) is expensive and time consuming in the deterministic methods, in this work they were evaluated using struc...

Reliable and continuous operation of ships is vitally important to the decision-makers. Driven by rising cost newbuilding ships, maintenance actions are needed on existing ensure safe enduring service beyond their initial design life. Extending ship life can provide economic operating profit promote sustainability. Meanwhile, during extended may involve higher failure risk additional expenditur...
