Production line scheduling method, production line system and non-temporary computer readable medium

A production line scheduling method, adapted to a plurality of jobs of an order, wherein the jobs pass a bottleneck station having at least one manufacturing machine, and the jobs respectively correspond to a plurality of job conditions, and the production line scheduling method comprising:

• performing a plurality of times of a schedule simulation algorithm on the jobs to sequentially establish a plurality of schedule simulation trees, and obtaining a job schedule and a simulated finishing period of each one of the jobs based on the schedule simulation trees, wherein each one of the schedule simulation trees comprises at least one scheduling route, and each scheduling route is generated from one of the times of performing the schedule simulation algorithm;
• transmitting the job schedule to a plurality of available manufacturing machines;
• and
• calculating a plurality of expected feeding times of each one of the jobs at a plurality of stations comprising the bottleneck station based on the simulated finishing period of each one of the jobs,
• wherein the schedule simulation algorithm comprises:
• performing a node expansion step based on at least one node expansion condition and the job conditions to obtain the scheduling route;
• wherein the at least one manufacturing machine obtains a pending job based on the transmitted job schedule and adjusts a processing parameter according to the obtained pending job.
