A dynamic production scheduling system and production scheduling method for a composite material workshop

Abstract

The invention relates to a dynamic production scheduling system and production scheduling method of a composite material workshop, which reads the perception data of the workshop IoT perception system in real time, including the real-time data of workshop workpiece processing and production disturbance event information, and obtains the processing status of workshop workpieces and equipment failures, Disturbance events such as production schedule delays and uniformity problems; based on perceived information, analyze the current resource usage and the impact of disturbance events, and feed back to the production scheduling calculation module in real time. Through the condensing, analysis and excavation of the actual processing data, a production scheduling knowledge base is formed, which stores all the process specification knowledge and process processing resource allocation knowledge of the workpiece processing process; when the production scheduling calculation module receives the production rearrangement order, it can The workpiece features automatically generate the corresponding process flow, the station corresponding to the process, the resource configuration data of equipment / personnel and the processing man-hour data of the process, so as to calculate and output the production scheduling plan to improve the production scheduling efficiency.

Description

technical field [0001] The invention relates to a dynamic production scheduling system and a production scheduling method of a composite material workshop, belonging to the technical field of automatic manufacturing. Background technique [0002] Composite products have the characteristics of multiple varieties, variable batches, long processing procedures, and mixed-line production. The production process is complex and changeable, and various disturbance events such as design changes and task changes often occur; composite material workshops need to accurately grasp the on-site production situation and future conditions. The production schedule fully considers the constraints of materials, tooling, production capacity, and delivery date, as well as factors such as equipment overload operation, so as to achieve reasonable rescheduling and balanced production for disturbance events. Therefore, solving the processing man-hour prediction problem based on production site data p...

Problems solved by technology

Generally speaking, the production scheduling methods and theories of the workshop are relatively mature, but the production scheduling problems targeted at the composite material workshop focus on the theoretical level compared with the actual production of the composite material workshop, and the specific practical guidance for the production scheduling of the composite material workshop is not clear, let alone a complete Dynamic Scheduling System
