Program to Produce Standard Shewhart Control Charts for the Statistics X-Bar and R or S, P, NP, C, or U

摘要

This report presents an interactive Fortran 77 computer program to developing and plotting standard Shewhart control charts for X-bar and R or s, p, np, c or u. It was developed on a VAX 11/750 computer using the VMS operating system. Central lines and control limits may be based on the input data, modifications of input data, or standard values. Input data is stored in separate named files so that it may be recalled, modified, or added to.
