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

Abstract

The invention relates to a dynamic production scheduling system and a production scheduling method for a composite material workshop. the methodcomprises the steps: reading perception data of a workshop Internet of Things perception system in real time, including workshop workpiece processing real-time data and production disturbance event information, and obtaining disturbance events, such as a workshop workpiece processing state, an equipment fault, a production schedule delay, an alignment problem, and the like; And based on the perception information, analyzing the current resource use condition and the influence generated by the disturbance event, and feeding back the current resource use condition and the influence to the production scheduling calculation module in real time. Throughcoagulation, analysis and mining of actual machining process data, a production scheduling knowledge base is formed, and all process procedure knowledge, procedure machining resource configuration knowledge and the like of the workpiece machining process are stored; And after the production scheduling calculation module receives the rearrangement instruction, the corresponding technological process, stations corresponding to the processes, and resource configuration data and process processing man-hour data of equipment/personnel can be automatically generated according to the characteristicsof the workpieces, so that the production scheduling scheme is calculated and output, and the production scheduling efficiency is improved.

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...
