Abstract

Economic Control Charts Economic Design Process Control Variables Control Charts
In this paper we present a comprehensive FORTRAN program that can be used to jointly determine the parameters of X̄ charts used in combination with either R or S charts. The parameters are determined using economic, statistical, or economic- statistical design criteria. The general cost model due to Lorenzen and Vance (1986) is used in economic and economic-statistical designs.
