Selection of descriptors for scratch degradation

Determine whether scratches in the Unified Embodiment Description should be represented by parameters such as angle, length, width, and depth or by aggregated measures such as area or volume.

Background

The Unified Embodiment Description requires degradation features to be translated into characteristics that can be related to functional behavior. For scratches, the case study used orientation, length, width, and depth, but the discussion recognizes that other representations, including aggregate geometric measures, may be more suitable. The choice remains unresolved because descriptor selection can affect the resulting embodiment–function relations.

For example, it remains unclear whether a scratch should be described by a set of parameters such as angle, length, width, and depth, or by aggregated measures such as area or volume.
