Table 2

Semantic and triangular fuzzy number expressions of functional relations.

Functional relationship	Fuzzy semantics	Triangular fuzzy number
The connection between and does not hinder the normal completion of the function.	Weak	(0, 0.1, 0.3)
The connection between and is beneficial but not necessary.	Unimportant	(0.2, 0.3, 0.4)
The connection between and is beneficial and the synergy is average.	Common	(0.4, 0.5, 0.6)
The connection between and is beneficial and the synergy is strong.	Important	(0.6, 0.7, 0.8)
The connection between si and sj is indispensable for the realization of new functions	Very important	(0.8, 0.9, 1)
