C Consideration of variability in the repair processes and in material properties
The task of Project Area C, “Consideration of variability in the repair processes and in material properties", is to develop methods which describe and assess the effects of the variability in regeneration on the functional characteristics of individual components and the overall capital good.
Based on an exhaustive inspection of the component condition before regeneration, a description of the functional characteristics is to be created after specific repair methods are applied. The special significance of Project Area C’s contribution is that the effects of this increased variance will be predicted, and thus controllable. This means that in future, deviations from the component’s new condition, which are not permitted today, could be tolerated. With the help of the methods provided by Project Area C it will be possible to describe which functional characteristics a capital good will have after regeneration is completed. In addition, minimum requirements, e.g. tolerances, can be formulated for the respective regeneration path. These requirements must be satisfied in order to ensure that a capital good has the desired functional characteristics after regeneration. Ultimately, through the methods developed by Project Area C, it will be possible to make decisions in favor of or against regeneration, based on an evaluation of the costs of production and logistics versus the benefit of a restored or even improved function.
