Multi-variety and small-batch multi-resource scheduling system and method based on digital twinning

Abstract

The invention discloses a multi-variety and small-batch multi-resource scheduling system and method based on digital twinning. The order optimization module splits an order and performs similar batch combination according to process similarity, and transmits the order as a basic task of production to the scheduling optimization module; a workshop data perception and disturbance event detection module is used for realizing real-time acquisition of 'man-machine-object-method-ring' state information of a workshop based on a perception data fusion workshop disturbance detection method, transmitting the acquired information to the disturbance event processing module for disturbance factor judgment, and transmitting the disturbance event to a scheduling optimization module to realize dynamic evolution of production; and a scheduling optimization module is used for receiving and processing information data transmitted by other modules and calculating to obtain a target scheduling scheme. According to the method, the problems of multiple product varieties and small batch in the order are solved, meanwhile, the problem of workshop multi-target multi-resource scheduling distribution is solved, and the flexibility and robustness of the workshop for sudden accidents and the effectiveness of a scheduling plan are improved.

Description

technical field [0001] The invention belongs to the technical field of digital twins, and in particular relates to a multi-variety and small-batch multi-resource scheduling method based on digital twins. Background technique [0002] In the face of the wave of economic globalization, the manufacturing industry has undergone major changes in recent years, and the customer-oriented "customized, order-to-order" service model has become the development direction of manufacturing enterprises. In order to survive in such a competitive environment, enterprises must quickly adapt to rapid changes in market demand by increasing operational flexibility, improving survival rates, shortening product cycles, and enhancing fault tolerance. Due to "customization, according to order", the workshop produces many varieties of products, small batches of production, frequent switching of production equipment and production routes, which not only increases the processing preparation time, but al...
