运用六西格玛方法提高叶丝填充值

Using Six Sigma Method to Increase the Filling Value of Cut Tobacco

运用六西格玛方法,对叶丝填充值这一卷烟生产工艺中的重要指标进行了改进。首先对制丝生产过程进行流程遍历分析,确定影响叶丝填充值的主要因素;进而运用潜在失效模式分析(FMEA)确定重要影响因素,在对各重要因素进行假设检验基础上最终确定影响叶丝填充值的关键因素。最后,针对关键因素,进行实验设计,确定最优参数组合,并纳入生产过程的控制范围。

Six sigma method has been used to improve the filling value of cut tobacco which is an important index in the tobacco production process.First the ergodic analysis of primary processing of cigarette was conducted to determine the key factors which affected the filling value of cut tobacco.Then the key factors which were the result of the potential failure mode analysis（FMEA） were determined based on hypothesis test.Finally,the design of experiment which focused on the key factors was carried on to confirm the optimal parameters and integrated into the control of the production process.
