Economic plan play an important role for every product. The priority of every sampling plan is the reduction in time and cost, which totally depends on the sampling plan, a decision regarding rejection and acceptance of the lot is taken on the basis of a single sample. The purpose of this paper is to design an economic model to obtain optimal total cost on the basis of average total inspection (ATI).In a single sampling plan, one sample of items is selected at random from a lot and the disposition of the lot is determined from the resulting information. | Cost optimization using acceptance sampling plan A statistical analysis with single sample
