Design and development of relational chain sampling plans [RChSP(0, i)] for attribute quality characteristics

The purpose of this research article is to provide a novel algorithm for the Relational Chain Sampling Inspection in order to emphasize quality products from the production sources. It is evident that whenever the items are costly or destructive, the customers expect good items. Hence, the qualities control practitioners’ emphasis on zero defective in such production process. But the Operating Characteristics curve of zero plans poorly discriminate the bad lots from a good one. Hence Chain Sampling Plans were recommended by Prof Dodge in the year 1955. The consumer expects that if the past results of inspection are to be used to sentence the current lot then the results of current sample should be used appropriately with previous results. Hence on the improvement of Chain Sampling Plans, the new sampling plans known to be Relational Chain Sampling Plans is being developed and is termed as RChSP(0, i). The measure of sampling plans such as operating characteristics function for Relational Chain Sampling Plan is derived and provided. The Designing Procedure for RChSP(0, i) is given and indexed through standard quality levels. Tables are constructed to facilitate Quality control practitioners to select and implement the RChSP(0, i)
