Article Abstract

A simple procedure for selecting the optimal economic design of an X-bar control chart for a single assignable cause system is presented that can be applied at the workshop level. The procedure has the following features: 1) assuming a constant production rate, the loss per item is chosen as the optimality criterion rather than the loss per hour; 2) inspection of the production process every h hours without preceding sampling inspection is included as an alternative.
