CONSTRUCTION AND SELECTION OF CHAIN SAMPLING PLAN WITH ZERO – INFLATED POISSON DISTRIBUTION

In this article given a construction procedure of attribute Zero – Inflated Poisson chain sampling plan-1 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 operating characteristic function. The procedure is developed to draw an Average Outgoing Quality Level (AOQL), curve by using Zero – Inflated Poisson chain sampling plan-1 and compare the different procedures in order to show the ambiguity of the procedure and their results
