情境
An automotive pivot pin moves through five sequential manufacturing stages—cutting, turning, heat treatment, grinding, and inspection—each requiring a specific machine resource. The petri net models part flow and resource reuse.
這張圖裡有什麼
看懂背後的決策。
01
Represented each manufacturing stage as a transition that consumes a part token and a machine token, then returns the machine token after completion.
02
Set initial markings with one raw material token and one token per machine to enforce single-part sequential processing.
03
Used an output place with no outgoing transitions for inspected parts to act as a terminal sink.
Reusable for any discrete manufacturing process where parts advance through stations and shared machines must be released for the next operation.
