Abstract

In practice, there are numbers of non-normal processes, the paper outlines quality control methods that used in non-normal process. On the basis of that, we privide a wider and easier method, using Johnson curves to describe non-normal data of control process.

Key words

Johnson curve / non-normal distribution / control chart
