| Summary: | 碩士 === 高苑科技大學 === 經營管理研究所 === 97 === Process capability index and control chart are important tools in the statistical quality control and they have a good effectiveness on monitoring and improving a process. The study considers the process capability index, quality loss function and skewness correction method to conduct a goal control chart. The proposed control chart is more suitable to be used to monitor a non-normal process than a traditional control chart. Moreover, the proposed control chart has low type I error probabilities on monitoring a non-normal process since it employs skewness correction method to determine control limits and provides a goal suggestion of quality improvement. This study also considers the proposed goal control chart using the top of a motor evaporator. In the example, the goal standard deviation and control limits can help practitioners in making production decisions and improving a process.
