In this paper Duncan's model for the economic design of an X¯-control chart is generalized using the Edgewarth approximation to the normal distribution. A single assignable cause process model is considered and its expected loss-cost function is presented. An improved version of the existing approximate analytical solution procedure to obtain the value of the design parameters (i.e., sample size n, sampling interval S. control limits coefficient k), is provided. Also, an oplimization technique based on Hooke and Jeeves's pattern search is developed and is employed on the loss-cost function to obtain the optimal design parameter values. Furthermore, a simplified scheme is proposed for selecting the design parameters so that the expected loss-cost is minimal for a specified level of consumer's risk. The proposed simplified scheme can be easily handled by a quality control practitioner at the workshop level. |
