Relative importance
aFuzzy scale
bDefinition
Explanation
Equal importance
Two activities contribute equally to objective
Weak importance
Experience and judgment slightly favour one activity over another
Essential or strong importance
Experience and judgment strongly favor one activity over another
Demonstrated importance
One activity is strongly favoured and demonstrated in practice
Extreme importance
The evidence favouring one activity over another is of highest possible order of affirmation
Intermediate values between two adjacent judgments
When compromise is needed
The intensity of importance definition is in accordance with the description proposed by [6, 7]; bminimum, most likely, and maximum values.
cΔ is a fuzzification factor.
