【摘要】：废钢铁合理分类是钢铁工业逆向供应链精细化管理的基础环节。为了实现种类繁多的废钢铁产品的充分利用,结合现有废钢铁循环利用方式,以来源、外观及成分等为分类指标,构建面向钢铁工业逆向供应链的废钢铁分类模型。针对现行的化学成分分类方法无通用性以及化学成分数据量庞大的问题,采用主成分分析法(PCA)对成分数据降维处理,再以层次聚类法获取初始聚类数及初聚类结果,然后结合蚁群聚类算法对初次聚类结果进一步优化,最终得到更为适用的化学成分分类指标。在应用案例中,分析常用的413种废钢铁,以9种化学元素为聚类指标,将废钢铁聚类优化为5大类废铁和7大类废钢,各大类间化学成分含量差异显著。该分类结果可用于解决废钢铁加工企业的仓库布局、废钢铁加工工艺决策以及钢铁生产企业生产配料等问题。
[Abstract]:Reasonable classification of scrap iron and steel is the basic link of fine management of reverse supply chain in iron and steel industry. In order to realize the full utilization of a wide variety of scrap iron and steel products, combined with the existing recycling mode of scrap iron and steel, The classification model of scrap iron and steel for the reverse supply chain of iron and steel industry is constructed by using appearance and composition as classification indexes, aiming at the problems that the current chemical composition classification methods are not universal and the amount of chemical composition data is huge. The principal component analysis (PCA) is used to reduce the dimension of the component data, and then the initial clustering number and the initial clustering results are obtained by hierarchical clustering method, and then the initial clustering results are further optimized with ant colony clustering algorithm. Finally, a more suitable classification index of chemical composition was obtained. In the application case, 413 kinds of scrap iron and steel were analyzed, and 9 kinds of chemical elements were used as cluster indexes to optimize the clustering of scrap iron and steel into 5 kinds of scrap iron and 7 kinds of scrap steel. The classification results can be used to solve the problems of warehouse layout, process decision of scrap iron and steel processing and production ingredients of iron and steel production enterprises.
