Demonstration of statistical approaches to identify componentʹs ageing by operational data analysis—A case study for the ageing PSA network

The paper presents some results of a case study on “Demonstration of statistical approaches to identify the componentʹs ageing by operational data analysis”, which was done in the frame of the EC JRC Ageing PSA Network. Several techniques: visual evaluation, nonparametric and parametric hypothesis tests, were proposed and applied in order to demonstrate the capacity, advantages and limitations of statistical approaches to identify the componentʹs ageing by operational data analysis. Engineering considerations are out of the scope of the present study.
