01
Model quality inspection as two competing transitions to represent pass/fail outcomes
02
Add a rework loop from rejected parts back to raw material
03
Keep the final passed-inspection place as a sink with no outgoing transitions
Use this pattern for discrete manufacturing processes with sequential stages, branch quality gates, and rework loops.
