Economic Design of Attribute Control Charts

Abstract

Abstract This paper proposes a production model for the current control of the number of defectives by an np-chart. An algorithm for determining the most economic control parameters is presented. An exceedingly simple procedure is suggested for designing control plans which approximate in cost the most economic control plans. This procedure is applicable at the workshop level.
