Multi-type steel batch rolling dynamic production planning system

Abstract

The invention discloses a multi-type steel batch rolling dynamic production planning system which is composed of a production plan information collection subsystem, a material supply information collection subsystem, a rolling production plan optimization subsystem and an output optimization information feedback subsystem. An output result of the system is fed back to an upstream production plan optimization subsystem through the output optimization information feedback subsystem, and dynamic change of materials and orders in the production process is combined to conduct production plan adjustment to ensure operation of the production planning system under the condition of minimum production cost. According to the system, correlation between available capacity, replaceability of the steel materials, blank and finished goods inventory, blank and production cost, batch production, tardy production and other factors are comprehensively considered in the rolling process, flexibility is improved, and the system meets the production status and the requirements of modern steel enterprises for multiple types and small batch.

Description

technical field [0001] The invention belongs to the technical field of steel rolling production planning and material resource planning, and in particular relates to a dynamic production planning system for batch rolling of multi-variety steel. Background technique [0002] Iron and steel rolling is the most commonly used production method for steel products. As iron and steel enterprises gradually transform from extensive production to intensive production, and pay more and more attention to product quality, thereby improving efficiency, the production planning and scheduling issues are also increasingly concerned by people. focus on. In addition, in recent years, the market demand for steel products has become more and more abundant, and the trend of small batches and multi-variety orders from customers has become more and more obvious. Therefore, it is necessary to realize the efficient formulation of the production plan of the steel rolling process in multiple time peri...

AI Technical Summary

Problems solved by technology

[0006] The present invention comprehensively considers the correlation between the available production capacity in the rolling process, the substitutability of steel products, and the stock of billets and finished products, the cost of billets and production, batch production, delayed production and other factors. Due to the shortcomings of insufficient flexibility, a dynamic production planning system for batch rolling of multi-variety steel is proposed to improve the accuracy and flexibility of forecasting and adapt to the market demand trend for diversified steel varieties and small orders
