High Performance Remaining Useful Life Prediction for Gearbox
2018 IEEE International Conference on Prognostics and Health Management (ICPHM), 2018Gearbox failure prediction is important for many applications. We present four approaches for predicting the remaining useful life of gearboxes. The first one is rule-based and the second one is a combination of damage curve approach and rule-based approach.

Methodologies for system-level remaining useful life prediction
Reliability Engineering & System Safety, 2016Abstract While most prognostics approaches focus on accurate computation of the degradation rate and the remaining useful life (RUL) of individual components, it is the rate at which the performance of subsystems and systems degrade that is of greater interest to the operators and maintenance personnel of these systems.

Predicting Remaining Useful Life with Uncertainty Using Recurrent Neural Process
2020 IEEE 20th International Conference on Software Quality, Reliability and Security Companion (QRS-C), 2020Recently deep learning based remaining useful life (RUL) prediction approaches have gained increasing attention due to their scalability and generalization ability. Although deep learning based approaches can obtain promising point prediction performance, it is not easy for them to estimate the uncertainty in RUL prediction.

Prediction of Mining Railcar Remaining Useful Life
2019Railcar or Rolling stock that is referring to all vehicles moving on railway, is one of the most important component of the rail transport system. In-operation failures of the railcar results delays in transportation and therefore predicting the remaining useful life (RUL) and accordingly considering the preventive maintenance activities are essential.

A Remaining Useful Life Prediction Framework for Multi-sensor System
2019 IEEE 19th International Conference on Software Quality, Reliability and Security Companion (QRS-C), 2019As the key technology of prognostics and health management, the remaining useful life (RUL) prediction can effectively reduce the fault probability and maintenance cost by evaluating the system operation condition. Due to the complex structure and versatility, an engineering system requires multiple sensors to monitor its condition.

Predicting the remaining useful life of plasma equipment through XCSR
Proceedings of the Genetic and Evolutionary Computation Conference Companion, 2019Predicting remaining useful life (RUL) of plasma equipment becomes an important issue for semiconductor manufacturing in this decade. If RUL can be accurately estimated, the schedule of maintenance can be proper to moderate the waste and cost of the production.
