| This topic is based on the actual requirements of the MES(Manufacturing Execution System)and WMS(Warehouse Management System)of the intelligent factory of company A for the automatic management of the system,and the automatic management of the information layer involved,the kitting of materials and the processing of disturbances in the production line to conduct research and application development on key back-end technologies to build an information-level automatic management and control system that adapts to the automatic adaptation of packaging material production lines and materials.The main research contents of the subject are as follows:Through the analysis and setting of the process control logic,management-control and nodes feedback of the human interaction in the MES operate-process of the intelligent factory,according to the division of the control process function and management information,the automatic management system is divided into WMS instruction management layer,production line management and control Layer,production line material centralized management layer and stand-alone production operation management layer.The four-layer system works independently.Through the monitoring of feedback signals and status,it forms an MES automatic operation mode based on the automatic driving of instructions,jobs,and materials,and the automatic operation of the production process,and forms a smooth switch to the manual mode.A corresponding monitoring system is formed for the work order operating status,equipment operating status and material status of the machine and production line,which is convenient for the production management personnel to control the automatic process.Secondly,in order to ensure the automatic process of material management and the construction of the automatic material all-in-one system in the workshop,according to the characteristics of the material and warehouse management of the soft package production line,the material kitting model,the calculation model of kitting priority and the kitting system are researched and given.The material lock model calculated for the material in the process.In the process of complete material collection,combined with the "push-type" material management mode,the stability of materials in the production workshop is ensured,which in turn ensures the stability of the production process on the production site.At the same time,in order to ensure the operation of the automatic control system and maintain the stability and order of the production process,the disturbance factors in the production process of the workshop are analyzed,and two disturbance events of insertion order and equipment failure are selected as examples,and a priority-based time is proposed.The back-shift strategy and the equipment sharing strategy based on the load amount solve the re-planning of the work order.At the same time,in order to solve other disturbance problems in workshop production,the sliding window algorithm and Johnson hybrid SPT algorithm are combined to realize the dynamic scheduling of workshop operations. |
