SELECTION OF MULTIPLE DEFERRED STATE MDS-1 SAMPLING PLAN FOR GIVEN ACCEPTABLE QUALITY LEVEL AND LIMITING QUALITY LEVEL INVOLVING MINIMUM RISKS USING WEIGHTED POISSON DISTRIBUTION

The selection principles have increased enormously in number since the first acceptance sampling plans were developed almost 80 years ago. The majority of these principles are characterized by the fact that they look upon producer and consumer as two opposing parties. However, on many occasions, e.g., in final inspection, producer and consumer represent the same party and, therefore, the used sampling plan should not make an attempt to discriminate between their interests. In this case the interest is to avoid wrong decisions, i.e., reject product of sufficient quality and accept product of insufficient quality. Thus, the natural objective in these cases is to use overall risk for a wrong decision as optimization criteria. Optimum result can be arrived further by the Weighted Poisson distribution. In this paper, a table and procedure are given for finding the Multiple Deferred State-1 (MDS-1) (c1, c2) sampling plan involving minimum sum of producer's and consumer's risks for specified Acceptable Quality Level and Limiting Quality Level using Weighted Poisson distribution. This is the case with so called "Multiple Deferred State-1 (MDS-1) (c1, c2) sampling plan for given Acceptable Quality Level and Limiting Quality Level involving minimum risk s using Weighted Poisson distribution".
