The aramis data challenge: Prognostics and health management in evolving environments

The objective of the Aramis Data Challenge is the creation of a public benchmark dataset for the problem of fault detection in evolving environments. A multi-component system in which the degradation of one component accelerates the degradation processes of the other components, thus modifying their lifetime distributions and the statistical properties of the monitored signals over time is considered. Here, we provide details with respect to the Challenge definition, the data collection and the evaluation metric.
