摘要：
A conventional cumulative sum control chart has a V-mask where each arm makes an angle theta with the horizontal and has a lead distance d. These parameters are usually related to h (=dA tan(upsilon), A is a scaling factor) and k(=A tan(upsilon)). Two systems of formulas are examined for deriving h and k for selected values of the in control and out of control average run lengths. This is the first time an exhaustive comparison has been made.
