Plate blank and contract transferring and matching method for improving utilization rate of plate blanks of iron and steel enterprise

Abstract

The invention relates to a matching link of a plate blank of an iron and steel enterprise, belongs to the technical field of automation and particularly relates to a plate blank and contract transferring and matching method for improving the utilization rate of the plate blanks of the iron and steel enterprise, comprising the following steps of: downloading plate blank information and contract information; establishing a mathematic model; carrying out parameter setting on the mathematic model; grouping the plate blanks and contracts; carrying out tabu search algorithm on each group of contract data and each group of plate blank data based on a multi-neighborhood to obtain a matching relation again; and checking a result of the step five; if the result meets the requirements, delivering and executing. Aiming at the condition that a plate blank and contract matching relation is unreasonable, the invention provides the plate blank and contract transferring and matching method, namely the plate blanks in all the contracts are taken off to break through the previous plate blank and contract matching relation; and on the precondition that a unit capacity is balanced, optimization and matching of all the plate blanks capable of being matched and the contracts capable of being matched can be carried out again, so that the matching quality of the plate blanks is effectively improved, the cutting loss amount of the plate blanks is reduced, the residual material amount of the contracts is reduced, the integrity of the contracts is improved and the delivery just-in-time of the emergent contracts is guaranteed.

Description

technical field [0001] The invention relates to the slab matching link of iron and steel enterprises, belongs to the technical field of automation, and in particular relates to a slab-to-contract matching method for improving the utilization rate of slabs in iron and steel enterprises. Background technique [0002] Most of the production contracts of iron and steel enterprises are formulated according to the specifications, steel grades, components, hardness and other requirements of the steel products proposed by users. In the process of steel production, firstly, the steelmaking and continuous casting production plan is arranged according to the production contract, and after the slab is produced, further processing such as hot rolling and cold rolling is carried out according to the requirements of the contract, and finally the final product is produced and delivered to the customer. However, the following reasons have led to excessive contracts and unreasonable matching ...

AI Technical Summary

Problems solved by technology

[0003] Aiming at the problems caused by the unreasonable matching between slab and contract in iron and steel enterprises, such as large amount of slab cutting loss, large amount of remaining material in the contract, and failure to deliver on time in the contract, the invention provides a slab and contract that improves the utilization rate of the slab. Switch to the matching method to achieve the purpose of maximizing resource utilization, improving customer satisfaction, and maximizing corporate profits
