A method for controlling the production capacity allocation of the whole process unit in a metallurgical enterprise

Abstract

The invention provides a metallurgical enterprise full-process unit production capacity distribution control method, which includes: establishing a metallurgical enterprise full-process unit production capacity distribution control model based on the production status of each metallurgical enterprise unit and the contracted processing path; determining the production capacity distribution situation of each unit , including the contract selection situation and contract processing sequence of each unit, and calculate the stability evaluation index value of the metallurgical enterprise's full-process unit capacity allocation control plan; conduct capacity allocation control based on the metallurgical enterprise's full-process unit capacity allocation control plan and the corresponding production contract , and make real-time adjustments to the production capacity distribution control plan of the full-process unit of the metallurgical enterprise; issue the current optimal distribution control plan of the full-process unit capacity of the metallurgical enterprise to the full-process unit for capacity allocation control. The present invention formulates a production capacity allocation plan by coordinating each unit, so that the needs of production equipment can be met as much as possible, the production of each unit can be carried out smoothly, the production process is more reasonable, and production switching is reduced.

Description

technical field [0001] The invention belongs to the technical field of metal material processing information, and specifically relates to a method for controlling the production capacity distribution of a full-process unit in a metallurgical enterprise. Background technique [0002] The unit load distribution problem in the process of metal material processing is the main content of the production management of metallurgical enterprises. The quality of capacity distribution is directly related to the equipment stability and operating efficiency of each unit in the production plant, product quality and production cost. [0003] Take steel mills as an example: large-scale iron and steel enterprises often cover multiple serial processing procedures including ironmaking, steelmaking, hot rolling, cold rolling, etc. Ironmaking uses iron ore powder and coke as the main raw materials, and after a series of smelting processes the final Forming molten iron; steelmaking is a smelting ...

AI Technical Summary

Problems solved by technology

Due to the dynamic change of unit status, there are many processing constraints in each process, and there are various types of materials to be considered, and the quantity is huge. Manually formulating a unit capacity allocation control plan cannot take into account the processing needs of multiple units at the same time; at the same time, this method is due to the lack of real-time It is impossible to dynamically consider the processing status of each unit, and formulate a unit capacity allocation control plan to ensure stable operation of the unit and qualified product quality; in addition, the execution response time of manually prepared reports is long, and the units of large metallurgical enterprises are mostly in continuous operation. This manual method cannot adapt to the continuous operation mode of the unit
