Abstract : A cost model is derived for the design of cumulative sum control charts using the Average Run Length to calculate the average time of out-of-control operation. The minimum cost design is obtained by employing the 'pattern search' technique. The nature of the loss-cost surface and the effect of the design variables on the loss-cost surface are investigated. The effects of the shift parameter (delta), the average time for an assignable cause to occur (1/lambda) and the cost factors b and c on the optimum designs and the loss-cost surfaces are also evaluated by numerical examples.
