Abstract

Disclosed is a smart factory dynamic collaborative scheduling method based on static scheduling prediction. After a workpiece enters into a production system, a corresponding workpiece agent is generated; every time after the workpiece agent enters into the production system or any of a processing procedure is completed, a processing unit agent is selected by the workpiece agent to perform processing procedures, a transportation unit agent is selected by the processing unit agent to transport workpiece, and if all of the procedures are completed, the transportation unit agent is selected by awarehouse unit agent to transport products to a warehouse. By means of the method, the problem of foresight lacking and overall concept lacking of a single agent of an existing multi-agent method is overcome, the foresight and overall concept of the single agent are improved through an experience summarizing mechanism and a global environment prediction mechanism, and the overall performance of the production system is optimized.

Description

technical field

[0001] The present invention relates to the technical field of workshop scheduling control, in particular to a dynamic collaborative scheduling method for smart factories based on static scheduling prediction Background technique

[0002] In today's era of advocating intelligence and big data, smart factories have become a new stage in the development of modern factory informatization. Smart factory is a new form of digital factory. It uses Internet of Things technology to monitor and manage production equipment and products. As an assistant, it assists managers to master the entire process. At the same time, it can use the data it collects to adapt and learn by itself. , and finally realize self-organization and self-decision in the production process.

[0003] In the smart factory environment, there are many disturbances, complex orders, production has great uncertainty and variability, and scheduling is very complicated. How to meet the real-time require...
