With the use of FNs, it is possible to analyze the real situation into the fuzzy value
The more the qualitative indexes approach the ideal maximal fuzzy value
, the more the magnitude approaches 1; by contrast, the more the qualitative indexes approach the ideal minimal fuzzy value
, the more the magnitude approaches 0.
The inference engine (Mamdani fuzzy inference system) performed fuzzy reasoning with fuzzy rules to generate a fuzzy value
For each objective we determine fuzzy value
of the degree to which a construction owner is striving in order to reach a given objective.
j] is a fuzzy value
(term) of linguistic variable [T.
ij] is fuzzy value
representing the preference of the i alternative in terms of the j criterion; [[?
Weights of criteria Fuzzy Value
Defuzzified and Normalized Value [W.
This step contains the process of the replacement of a fuzzy value
with a crisp output, comprising a procedure of weighting and averaging the outputs from all of the individual fuzzy rules.
For Rule #1, this results in assigning attribute "Project Risk" the fuzzy value
"Low" representing a new fuzzy level-three description.
The normalized weight vector is calculated via equation (8) to convert fuzzy value
Fuzzification module transforms a crisp input to its corresponding fuzzy value
The model suggested in this article treats parameter [lambda] as a dependent fuzzy value
