Semantics of temporal relations and expression of triangular fuzzy numbers.

Relationship	Temporal correlation	Fuzzy semantics	Triangular fuzzy number
Parallel	is executed before , but the result of execution has nothing to do with .	Weak	(0, 0.1, 0.3)
Overlapping	is executed before , and the partial execution result of the first can create conditions for the second.	Unimportant	(0.2, 0.3, 0.4)
Sequential	must precede and create conditions for .	Common	(0.4, 0.5, 0.6)
Cycle	must precede and circulate once to create conditions for each other.	Important	(0.6, 0.7, 0.8)
Coupled	and go back and forth many times to create conditions for each other.	Very important	(0.8, 0.9, 1)
