Compound Uncertainty Quantification and Aggregation for Reliability Assessment in Industrial Maintenance

The mounting increase in the technological complexity of modern engineering systems requires compound uncertainty quantification, from a quantitative and qualitative perspective. This paper presents Compound Uncertainty Quantification Aggregation (CUQA) framework to determine outputs along with determination greatest contribution via global sensitivity analysis. was validated two case studies: bespoke heat exchanger test rig simulated turbofan engine. results demonstrated effective measurement individual impact on system reliability. Further work will derive methods predict in-service incorporation more complex studies.
