After completing the matrix of SRMF, some data may be misleading. In SRMF, all factors are
not related to each other, and it is also possible that there exist no causality relations between
them. To convert SRMF into FMF, experts’ opinions are required. In FMF, only numerical fuzzy
elements that show the causality relation are represented. When the data in the SRMF is
analyzed, some vectors are related to each other by accident. The vectors may have close
causality relation; while there is no relation or connection between them in the real world.
Irrelevant relations are easily ignored according to the experts’ opinions.
3.2.7. Graphical demonstration of FCM
The aim of FCM process is mapping the factors/criteria in different projects. In the final
graphical representation of FCM, each arc between two factors ‘‘i’’ and ‘‘j’’ has a positive or
negative weighted value (±
