Chain Sampling Plan for Variable Fraction Non-Conformities

Abstract

In this article a design procedure of attribute chain sampling plan for variable fraction defective is presented using stochastic differential equations. An iterative procedure for finding the parameters of the plan satisfying the given conditions with respect to producer quality level is given. Tables are constructed for easy selection of the parameters which are readily available to apply in the shaft floors of production process. The performance of the chain sampling plan for variable fraction defective is also discussed by determining the new operating characteristic function.
