摘要

本案例包含四个实践问题,以帮助培养学生对过程能力的理解。摘自UVA-OM-1492 Rev. 2013年3月18日过程能力:实践问题供应商为客户制作包装箱,包装箱长度平均分布在150mm左右。由于灌装机有空腔,纸箱长度不能超过157mm,不能短于143mm。工艺标准差为2.5mm。a.什么是过程能力(Cp)?b.在Excel中使用NORMSDIST计算流程的缺陷百分比. . . .

Process Capability: Practice Problems
This case contains four practice problems to help develop student understanding of process capability. Excerpt UVA-OM-1492 Rev. Mar. 18, 2013 PROCESS CAPABILITY: PRACTICE PROBLEMS 1. A supplier makes packaging cartons for a customer, with a length normally distributed around a mean of 150 mm. Due to the cavity in the filling machine, the carton must be no longer than 157 mm and no shorter than 143 mm. The process standard deviation is 2.5mm. a. What is the process capability (Cp)? b. Use NORMSDIST in Excel to calculate the percent defects of the process. . . .
