Description: This application simulates the Xbar and S control charts, that are some of the tools of statistical quality control, or statistical process control (SPC).

It computes the ARL for different mean and sigma shifts. Concretely, the shifts are measured by d = abs(m1 - m0) / sigma0 and by r = sigma1 / sigma0.

In addition, it measures the number of times that each control chart shows an out-of-control alarm. For example, it is possible to see that the Xbar control chart detects sigma shifts too.

The application permits to simulate the effect of the length of Phase I in the real performance of the scheme Xbar-S (in-control and out-of-control ARLs).

At this moment the application languages are Spanish and English.

This application is also available for other platforms. Just search in their stores.; MoreLess
