Short Description

An AND-Split Operator is a subtype of an AND Operator.
It is responsible for splitting the control flow in at least two different branches, which are executed parallely.[1]
That is why AND-Split has just one incoming arc and multiple outgoing arcs:
C_as = {c ∈ C | l(c) = and ∧ |cin| = 1}. [2] The AND-split represents a parallel execution. It waits to get the control flow on its incoming arc before allowing the control flow to continue on all its outgoing arcs.[3]

The XOR-Split represents an exclusive choice between one of several alternative branches within the process. As a result, an XOR-Split triggers exactly one of several possible following events. Which of the possible branches is activated depends on the process conditions.[4][5][6]
