초록
With the advent of lean-six sigma era, an extensive use of analytic tools such as control charts is required in the field ofmanufacturing. In relation to statistical quality control (SQC) or process control (SPC), the Korean standards have undergonea meaningful change. In this study, the theoretic backgrounds for evaluating the control limits in connection with the variablecontrol charts are examined in view of better understanding the related constants and coefficients. This paper is intended tohelp the quality control practitioners understand the mathematical backgrounds by comparing related quality control constantsand also to encourage them to make use of and to take the advantage of the variable control charts which are very useful forimplementing the concept of lean-six sigma in many industrial sites.
