为提升烟支卷制综合品质控制的稳定性，分析了T 2、MCUSUM和广义方差3种典型多元统计控制图用于卷制品质控制的构建方法，对比了不同控制图对异常波动的检出能力，应用筛选出的多元统计控制图考察了不同机组、3种牌号卷烟综合卷制品质的稳定性。结果表明：MCUSUM控制图对烟支质量、圆周、吸阻、长度、硬度、总通风率等物理指标小偏移的检出能力明显高于T2控制图，更容易发现烟支卷制过程中均值向量的异常波动，与广义方差控制图结合使用，能够保证卷制过程品质的均值偏离程度和波动程度同时受控。对3种牌号卷烟及PROTOS 70、PROTOS M5两种卷接机组的卷制品质分析显示，同一机组对不同牌号卷烟的卷制加工品质稳定性不同，而同一牌号卷烟在PROTOS M5、PROTOS 70两种卷接机组加工品质的稳定性也存在较大差异。
為提升煙支捲製綜閤品質控製的穩定性，分析瞭T 2、MCUSUM和廣義方差3種典型多元統計控製圖用于捲製品質控製的構建方法，對比瞭不同控製圖對異常波動的檢齣能力，應用篩選齣的多元統計控製圖攷察瞭不同機組、3種牌號捲煙綜閤捲製品質的穩定性。結果錶明：MCUSUM控製圖對煙支質量、圓週、吸阻、長度、硬度、總通風率等物理指標小偏移的檢齣能力明顯高于T2控製圖，更容易髮現煙支捲製過程中均值嚮量的異常波動，與廣義方差控製圖結閤使用，能夠保證捲製過程品質的均值偏離程度和波動程度同時受控。對3種牌號捲煙及PROTOS 70、PROTOS M5兩種捲接機組的捲製品質分析顯示，同一機組對不同牌號捲煙的捲製加工品質穩定性不同，而同一牌號捲煙在PROTOS M5、PROTOS 70兩種捲接機組加工品質的穩定性也存在較大差異。

In order to improve the stability of comprehensive cigarette quality control, the methods for the establishment of the three typical multivariate statistical control charts (T2, MCUSUM, and generalized variance control charts) used in cigarette manufacturing quality control were analyzed and their competence for detection of abnormal fluctuations were compared. The choice control chart was used to evaluate the stabilities of comprehensive manufacturing quality of three cigarette brands and different cigarette makers. The results showed that MCUSUM control chart was more competent for the detection of minor deviations concerning weight, circumference, draw resistance, length, hardness and total ventilation rate of cigarette than T2 control chart, and more sensitive to the abnormal fluctuations of mean value vectors in the process of cigarette manufacturing; by combining with generalized variance control chart, it could ensure the deviation and fluctuation degrees of mean values to be controlled simultaneously in the process of cigarette manufacturing. The manufacturing quality of three cigarette brands manufactured by PROTOS-M5 maker and PROTOS-70 maker was analyzed, the results indicated that the stability of manufacturing quality for the same maker was dependent on cigarette brands, and that for the same brand dependent on makers.
