where

Constraints for select Produce
select Produce (node) ≠ ∅

CtlOp(node, I ) =

ConsumeAll({(t j , in j ) | 1 ≤ j ≤ n}) where
[t 1 , . . . , t n ] = firingToken(I )

GateTransitionPattern(node) =

9.3 Event Rules
StartEventTransition(node) =
choose e ∈ trigger(node) StartEventTransition(node, e)
StartEventTransition(node, e) =
if Triggered(e) then Produce(startToken(e), out)
ConsumEvent(e)
EndEventTransition(node) =
if Enabled(in) then
Consume(firingToken(in), in)
EmitResult(firingToken(in), res(node), node)
