2.3.2. Elasticity Analysis

The elasticity describes the ratio of the change of an output quantity, related to the change of the input quantity, and therefore results in the case of the sensitivity analysis for a physical quantity to

$$
\epsilon\_{\text{phys}} = \frac{r\_{\text{phys}}}{r\_{\text{servs}}},
\tag{2}
$$

where *r*phys describes the relative change of the physical quantity between the two simulated machine models. This allows for capturing for each model how much a certain quantity changes when the parameter under investigation is modified.
