The invention provides a work order synchronization method and system based on a discrete scene, equipment and a storage medium, and the method comprises the steps: detecting a production plan state, obtaining a second plan number and a material stock number, updating a production plan according to the second plan number and the material stock number, and obtaining a second production plan; dispatching work according to the second production plan, generating a production work order, updating the form content of the process work report according to the production work order, and obtaining a second process work report; on the basis of the second production plan and the second process report, updating form contents of reworking and repairing, production materials, production feeding and material picking and returning details; and according to all the updated form contents, judging the states of the production plan, the production order and the process work report, and performing updating. The planned production scheduling data can be quickly restored in the production scheduling link, the working efficiency is improved, corresponding customer requirements can be scheduled in real time according to customer requirements and actual field material conditions, and the material utilization rate is improved.

The invention belongs to the technical field of production plans, and discloses a job shop scheduling method based on a graph neural network, and the method comprises the steps: enabling the sequence of internal production processes of workpieces and the machine assignment condition between the workpieces to be visible; designing a reward function to evaluate the scheduling decision; embedding and extracting node feature information of the disjunction graph; and carrying out scheduling strategy network learning and graph neural network parameter adjustment. The generalization ability of the manufacturing system job shop scheduling method is improved, and the method can be applied to job shop scheduling of different network scales in the same system. According to the method, the job scheduling problem is subjected to network topology, the generalization ability of a scheduling algorithm is improved, the job shop scheduling problem can be effectively solved, and the method has the characteristics of high universality and high adaptability.

Disclosed herein methods for scheduling the automated manufacturing of mattresses. Aspects include receiving a plurality of customer orders for mattresses, wherein each of the plurality of customer orders includes a due date and organizing the plurality of customer orders into production batches based on the due dates. Aspects also include analyzing a first production batch of the daily production schedule and responsively creating an optimized hour production batch and based on a determination that the optimized first production batch exceeds a performance threshold 1, dispatching the first hourly production batch to an automated manufacturing system for production. Based on a determination that the optimized first hour production batch does not exceed the performance threshold, aspects further include analyzing a second production batch and modifying the optimized first production batch and the second production batch to create an optimized second production batch.

Cap teeth unit in variable teeth series is adopted in system of traveltime. Under precondition of not changing integral structure of system and relevant technical data, changing actual number of teeth and round rotation angle position of head sheave by altered number of teeth of the cap teeth unit form basic timing quantity of mechanical timer in series of cap teeth unit. Advantages are: enriching production specifications, and shortening production cycle.
