Applications of smart technologies to mobile health care
The proposed methodology
FGM for aggregating multiple experts’ evaluation results
- As important as: \( \tilde{a}_{ij} (k) \) = (1, 1, 3)
- Slightly more important than: \( \tilde{a}_{ij} (k) \) = (1, 3, 5)
- Considerably more important than: \( \tilde{a}_{ij} (k) \) = (3, 5, 7)
- Extremely more important than: \( \tilde{a}_{ij} (k) \) = (5, 7, 9)
- Absolutely more important than: \( \tilde{a}_{ij} (k) \) = (7, 9, 9)
ACO for deriving the fuzzy eigenvalue and eigenvector
FWA for evaluating the sustainability of a smart technology application to mobile health care
