面向钢铁工业逆向供应链的废钢铁分类方法研究
The classification method research of scrap iron and steel based on reverse supply chain
摘要
Abstract
The reasonable classification of iron and steel scrap is the basic link of the delicacy management in the reverse supply chain for the iron and steel industry .For making full use of scrap iron and steel ,the cyclic utilization is analyzed and a classifica-tion model based on the source ,geometry appearance and chemical composition is proposed for the scrap iron and steel in the re-verse supply chain .With the low versatility of the existing classification and the huge data of the chemical component ,the dimen-sion matrix composition data is reduced by the using of the principal component analysis at first .And then the initial cluster num-ber and initial clustering result is obtained by hierarchical clustering method .Finally,a suitable classification has been construc-ted.In the end,the initial clustering result is optimized by applying ant colony algorithm .In a case of classification of 413 types of scrap iron and steel,9 kinds of chemical elements are regarded as an index of calculation .Finally,these scrap iron and steel can be classified in 5 species of scrap iron and 7 species of scrap steel .The chemical composition of each species is significantly dif-ferent.This conclusion can solve the problems of warehouse layout and process decision and production scheduling in the iron and steel industry .关键词
