为优选出水泥生产的运转参数的合理范围 ,对冀东水泥厂 NSF窑运转参数与水泥强度及能耗有关的 78个记录进行数据包络分析 ,从中挑选出热耗低而熟料的 2 8d与 3d强度高的相对有效记录 6个 ,再对这 6个记录进行系统重构分析 ,找出了影响热耗、熟料 2 8d与 3d的强度的主要因素及各因素比较合理的取值范围

Application of DEA Method and System Reconstruction Analysis in the Cement Production LU Lin-zheng,LAN Ming-zhang,WU Wen-jiang (School of Materials,Beijing University of Technology,Beijing 100024,China)In order to produce cement with high quality in low energy consumption, select the reasonable range of operating parameters in cement producing process by analyzing the operating parameters of NSF in Jidong Cement Plant, the strength of cement and 78 records related to the energy consumption and used the data envelopment analysis (DEA) to select 6 comparatively valid records with low heat consumption and high strength of 28 days and 3 days. Furthermore the 6 records were analyzed with the system reconstruction analysis (DMU) method from that we find the major factors which influenced the heat consumption and the clinker strength of 28 days and 3 days and also the span of these factors.data envelopment analysis(DEM); decision making unit; system reconstruction analysis(DMU); operate parameter
