This application simulates the ARL of an EWMA control chart for different smoothing and control limits. The 4 available combination of smoothing and control limits yield an in-control ARL of 370.

The EWMA control chart is one of the tools of statistical process control (SPC) or quality control.

It is possible to change the value of the mean and sigma of the Normal distribution used in the simulation. Concretely, the shifts are measured by d = abs(m1 - m0) / sigma0 and by r = sigma1 / sigma0.

At this moment the available languages are Spanish and English.
