Sequence¶
Generalization is DeterministicImperative.
Superclass hierarchy
Definition¶
<font color””#2d2d2d”>A Sequence controls the order of Activities or Steps by defining a simple sequence.</font>
Examples¶
A Sequence might contain two Sequences of Activity – one for Round 1 Activity of the Research and the second for Round 2
Explanatory notes¶
Unlike TemporalConstraints, Sequence is NOT pairwise. However, a group of TemporalConstraints can specify an order with more precision than Sequence.
