    Chokethaworn, Nantawong
    Abstract:
    In production processes, there are two types of variations that affect production quality - - variations produced by chance causes and variations produced by assignable causes. One of the main instruments in quality control used to control quality by distinguishing between variations produced by chance causes and a real process...

  • 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...
