Economic, Statistical, and Economic-Statistical Design of Attribute Charts

We present a FORTRAN program that can be used to determine the economic, statistical, or economic-statistical design of a fraction defective or defects per unit chart. In the economic design approach, the general Lorenzen-Vance cost function is minimized. In statistical design, we find designs which meet constraints on average run length while in control and while in a variety of out-of-control states. Economic-statistical designs are based on Saniga's approach, which minimizes the cost function subject to statistical constraints.
