  • Economically optimal control charts for two stage sampling

    Creator:
    Hall, Kathryn B.
    Abstract:
    Control charts are designed to monitor population parameters. Selection of a control chart sampling plan involves determination of the frequency of samples, size of each sample, and critical values to determine when the system is sending an out-of-control signal. Since the main use of control charts is in industry, a...

  • Multivariate control charts for nonconformities

    Creator:
    Chattinnawat, Wichai
    Abstract:
    When the nonconformities are independent, a multivariate control chart for nonconformities called a demerit control chart using a distribution approximation technique called an Edgeworth Expansion, is proposed. For a demerit control chart, an exact control limit can be obtained in special cases, but not in general. A proposed demerit control...
