摘要
制造执行系统(MES)可以提升轮胎制造企业的运营水平,同时也集成了海量的制造环节数据,能够应用数据挖掘技术进行充分利用和挖掘,使信息更有价值。基于MES数据仓库中提取的轮胎质检工段的均匀性检测数据,采用特征选择的方法分析影响各规格轮胎均匀性的质量因素及权重,比较了基于信息论、统计、相似度的几种算法的应用效果。对于均匀性数据的冗余属性问题,利用LFS+CFS进行分析,发现降维后的属性在预测均匀性等级、归档压缩和质量管理方面展现出了价值。
Abstract: MES system could help the tire manufacturer improve their operations, integrate the manufacturing domain data, and could be benefited by data mining technology. Based on the tire uniformity test data extracted from the MES data warehouse, the influence factors on the tire uniformity attribute were analyzed by feature selection method. The application effects of several kinds of algorithm according to information theory, statistics, similarity were compared. The solution of LFS + CFS was applied to eliminate the uniformity attribute redundancy feature. The attributes value went up by dimensionality reduction in the fields of uniformity forcast, archive compression and quality control.
