Whole-process inventory level early warning and control method for iron and steel enterprise

Abstract

The invention relates to a whole-process inventory level early warning and control method for an iron and steel enterprise. The method comprises the following steps: a step of preparing a precursor; the method comprises the following steps: step 1, starting an online production process data collector; the method comprises the following steps: step 1, collecting historical production actual performance to construct a learning sample, step 2, establishing an average turnover time analyzer of materials among reservoir areas, and obtaining information by utilizing an online production process datacollector, step 3, utilizing the average turnover time analyzer of the materials among the reservoir areas constructed in the previous step, and step 4, monitoring each reservoir area. 5, predictinga production control strategy; 6, judging the state of the reservoir area, and sending out early warning information, and 7, feeding back the early warning information to a production execution mechanism, and proposing a new production control strategy. Compared with a current manual inventory level monitoring scheme, the method is short in response time, high in real-time performance and beneficial to quick adjustment of a production control platform, and therefore controllability and stability of the production process are improved.

Description

technical field [0001] The invention relates to a control method, in particular to an early warning and control method for the whole process inventory level of iron and steel enterprises, and belongs to the technical field of metal material processing information. Background technique [0002] The early warning and control of inventory level in the process of steel material processing is the main content of production management of iron and steel enterprises. A reasonable inventory level is directly related to the continuous and stable operation of the equipment of each unit in the production plant, product quality and production cost. [0003] Large-scale iron and steel enterprises often cover multiple serial processing procedures including ironmaking, steelmaking, hot rolling, cold rolling, etc. There is a warehouse area between adjacent processing procedures for storing work in progress, which is the product of the previous process. The product is also the raw material of...

AI Technical Summary

Problems solved by technology

[0004] At present, in the actual production of large-scale metallurgical enterprises, the inventory level control of each reservoir area is mainly monitored through regular manual report reports. Due to the continuity of steel plant production, the inventory level changes in real time, and manual monitoring of the inventory level is difficult to ensure real-time performance. At the same time, The execution response time of manually formulating reports is long, and most of the units of large iron and steel enterprises operate continuously. This manual method cannot adapt to the continuous operation mode of production actuators.
