情境
An injection molding cell produces inspection covers through clamping, injection, cooling, ejection, and quality inspection, with failed parts sent to rework rather than scrap.
這張圖裡有什麼
看懂背後的決策。
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.
