Traditional methods for predicting remaining useful life (RUL) ignore the correlation between physical world data and virtual data, leading to low prediction accuracy of RUL affecting normal working rolling element bearing (REB). To solve above problem, we propose a hybrid method based on digital twin (DT) long short-term memory (LSTM). The combines high simulation capabilities DT strong proces...

Predictive maintenance based on performance degradation is a crucial way to reduce costs and potential failures in modern complex engineering systems. Reliable remaining useful life (RUL) prediction the main criterion for decision-making predictive maintenance. Conventional model-based methods data-driven approaches often fail achieve an accurate result using single model system featuring multi...

During transportation, prediction of the Remaining Shelf-Life (RSL) Fresh Fruits and Vegetables (FFVs) is critical for planning quality cost estimation. The Internet Things (IoT) enables measured environmental variables to be processed in real-time. However, there a need validated, real-time computational method that translates measurements dynamic RSL estimates. Most existing generic models FF...

The failure of critical components in physical systems may have negative consequences on the availability, the productivity, their security and on the environment. Thus, the assessment of the critical component’s health condition, which can be done in the diagnostic and prognostic framework, should be constantly ensured. In this paper, a contribution on the assessment of the health condition of...

Machine performance degradation assessment and remaining useful life (RUL) prediction are of crucial importance in condition-based maintenance to reduce the maintenance cost and improve the reliability. They provide a potent tool for operators in decision-making by specifying the present machine state and estimating the remaining time. For this ultimate purpose, a threestage method for assessin...

Many of fossil power plants, which were constructed during 1960's and 70's and exceed more than 10,000 working hours, have presently been operating while they have been receiving progressive damage, mainly from creep, as the time proceeds.[I, 2] Furthermore, by shifting the base load of power from fossil power plants to nuclear power plants, they are faced to even more severe operating conditio...

life cycle assessment (lca) is one of the decision support systems which can be considered for assessing the different approaches of waste management. however, it only considers environmental effects and ignores other decision making options such as economic and social effects of solid waste management. in this research, we consider a combination of three decision making options including en...
