Abstract. A mixed acceptance sampling scheme actually consists of two stages. The first stage sampling is concerned with variable criteria and the second stage sampling is considered with attribute criteria. In this paper, the variable criteria when the fraction defective is not a constant is taken into consideration and a new design procedure of product control for variable non conformities using a system of equations is presented. An iterative procedure of finding the parameters of the sampling plans are obtained by using new algorithm presented in this paper. Tables are constructed for selecting the parameters which will facilitate the shaft floor engineers.
