Embodiment

[0219] Embodiment: adopt the actual production data of a steel factory for 20 consecutive days. The data includes slab and contract data, and the data scale is as follows:

[0220]

[0221]

[0222] Adopt the method of the present invention, obtain above-mentioned 20 groups of data transfer matching schemes and the original matching scheme comparison result is as follows:

[0223]

[0224]

[0225]

[0226] The results show that the conversion matching scheme obtained by using the slab and contract conversion matching method described in the present invention, compared with the original matching scheme, has an average reduction of 28.57% in the amount of cutting loss, and a reduction of 9.71% in the number of cutting blocks; the contract Completion increased by 6.81%; urgent contract completion increased by 9.20%; contract overrun decreased by 25.28%, proving that this method can improve slab utilization, reduce waste of resources, ensure on-time delivery of con...

Abstract

A re-matching method of slab-order for improving slab utilization in iron and steel plants, comprising the steps of Step 1: formulating a mathematical model according to information of slabs and orders, so as to quantitatively describe the optimization problem of slab-order matching; Step 2: dividing the slabs and orders into groups; Step 3: generating a new slab-order matching relationship for each group of slabs and orders by using a multiple neighborhoods based tabu search algorithm on the basis of the formulated mathematical model, tries to re-optimize the matching relationship with consideration of the original slab-order matching relationship and the load balance of all equipment units, so as to improve the slab-order matching relationship, decrease the slab cutting loss, reduce the redundant slab weight of each order, and improve the integrity of an order, thus improving slab utilization, ensuring to deliver an urgent order on time, and improving the customer satisfaction.

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 ...
