Parker weights revisited
Web17 Nov 2024 · The NASA-TLX weight of the most important dimension (MD) is 0.33, and the corresponding AHP weight is higher than that. This result highlights the unnatural upper bound of the original NASA-TLX weighting. Figure 1b describes the mean scores and the dimension weights for pilot ID7.
