Economic statistical design of x? control charts for systems with weibull in-control times

This paper considers the economic statistical design of X¯ control charts with Weibull failure properties. A Weibull failure model is appropriate for many systems in electrical and mechanical industries. The economic statistical control chart design model is developed and illustrated by two examples. It is shown that for some situations, the increase in costs associated with the improved statistical performance may not be significant compared to the economic design.
