Economic, Statistical, and Economic-Statistical X̄ Chart Designs

Abstract

A FORTRAN program that enables users to determine economic, statistical, or economic-statistical X̄ chart designs is presented. Economic designs are designs that minimize cost as measured by the Lorenzen-Vance cost function. Statistical designs are designs that satisfy a series of average run length constraints associated with various degrees of shift in the process mean. These two concepts are combined to find economic-statistical designs, where cost is minimized subject to average run length constraints.
