Scheduling sub-system of three-level production planning system for steel-making enterprises

Abstract

The invention relates to a scheduling sub-system of a three-level production planning system for steel-making enterprises, which comprises the steps of establishing a three-level production planning system by applying a manufacturing execution system, wherein the three-level production planning system comprises a schedule planning module, a steel tapping planning module, an addition planning module, an image displaying module, a plan issuing module, a heat determination module and process control system plan receiving module; receiving an ERP (Enterprise Resource Planning) schedule plan by theschedule planning module; compiling a steel tapping plan through scheduling, adding the steel tapping plan to the image displaying module for processing through the addition planning module; issuinga production task according to a production plan determined by scheduling, and receiving the production plan by a process control system outside the three-level production planning system; and receiving process data, actual performance of continuous casting, continuous casting head and actual performance of a casting blank through the process control system, and determining the heat. The scheduling sub-system has very high operability, meets the actual requirements, not only can coordinate the production, but also can smooth the production rhythm, and reduces the occurrence of a casting interruption accident.

Description

technical field [0001] The invention relates to a production planning system, in particular to a scheduling subsystem of a three-level production planning system of a steelmaking enterprise. Background technique [0002] The production planning system of iron and steel enterprises is centered on the converter process, which does not match the current mode of organizing production centered on continuous casting. The existing production planning system lacks an overall plan for molten iron and scrap steel, and cannot match the enterprise's consistent system. The existing production planning system cannot dynamically generate and adjust the production plan, and the production plan cannot reflect the production situation of the enterprise in real time. The existing production planning system only has the sequence of furnaces in each process without the concept of accurate time, and the production rhythm is completely controlled by scheduling. , the system cannot provide help. ...
