Steelmaking production plan intelligent scheduling method based on big data rule self-learning

Abstract

The invention discloses a steelmaking production plan intelligent scheduling method based on big data rule self-learning, and the method mainly comprises the following steps: 1), forming a schedulingdecision table according to historical scheduling records, alignment time, scenes and scheduling operation; 2) rule mining: generating a rule base from historical records by adopting rule mining algorithms such as a rough set and deep learning; 3) plan arrangement: based on a continuous casting machine plan of actual data, based on a bottom layer equipment scheduling plan of container tracking technology, a production operation plan based on a time parallel back calculation method; 4) disturbance rearrangement: realizing intelligent rearrangement based on a rule description mode of'disturbance+ scene description + adjustment strategy 'and an expert rule base; and 5) plan display: displaying the operation plan through a Gantt chart, and providing dynamic interface adjustment. By means of the method, efficient and orderly operation of the steelmaking-continuous casting production process is ensured, the production and operation cost is reduced, energy is saved, consumption is reduced, the production efficiency is improved, and maximization of enterprise benefits is achieved.

Description

technical field [0001] The invention belongs to the technical field of intelligent scheduling of steelmaking production process, and specifically relates to a method for rearranging steelmaking production operation plans under disturbance based on self-learning of big data rules. Background technique [0002] During the production process of steelmaking, molten iron, molten steel and steel scrap are circulated between various processes through containers. From the molten iron entering the steelmaking workshop to the molten steel being injected into the continuous casting machine, the whole process needs to go through multiple processes, and each process has multiple equipment. The operation plan based on the topological diagram of the steelmaking process is the basis for ensuring the normal operation of the steelmaking process. However, the on-site process is complicated, there are many procedures, and frequent disturbances occur, and the prepared operation plan in units of ...
