摘要
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.
