Acceptance sampling plans are the practical tools for quality assurance applications involving product quality control. Acceptance sampling systems are advocated when small sample size are necessary or desirable towards costlier testing for product quality.
Quality Decision Region (QDR) indexed plan provides a method for designing sampling plan based on range of quality, instead of point wise description about quality. The QDR indexed plan has been experimented for Selection of Repetitive Deferred Sampling Plan which provides higher probability of acceptance compared with plan designed through specified quality levels.
Quality decision region (QDR) proposes wider potential applicability in industry ensuring higher standard of quality attainment for product. This paper provides a new procedure for Selection of Repetitive Deferred Sampling Plan indexed through Quality Decision Regions. New operating ratios are introduced towards designing such sampling plan. Further conversions of parameters are also attempted. Numerical illustrations are provided for selection of plan.
