grey level when the index is around 1. For those cells, it is no clear whether it is the
crate or the box that provides the best solution.
4.3 Discussion
The GWP results presented for the average cases reveal only that, in the defined
specific scenario, crates provide a better solution than boxes, regarding this indicator. Instead, considering the variability of parameters like logistic distance and
case height allows identification of the range of situations where this conclusion
applies.
