Author(s): S Devaarul and K Jothimani
Abstract: Repetitive Group Sampling Plans are widely used in industries for inspection of lots comprises of components or products. In RGS plans if the sample result does not lead to either acceptance or rejection of the lot then it is discarded and a new sample is drawn and the procedure is continued until the lot is sentenced. However in modern industries if the lots are not accepted based on the few sample results then there may be heavy loss in terms of money, huge cost in terms of sampling inspection, etc. Hence producer may face severe risk during such circumstances. Also customers may lose hope on the producer and the relationship between them may be at stake. The major setback of RGS while implementation is, it is not advantageous when the lot size is small. Hence to offset the disadvantages, new algorithm called as Relational Repetitive Group Sampling is given and new types of Relational Repetitive Group Sampling Plans are developed. It is termed as RRGS Inspection plans and the efficiency measures are derived. Tables are constructed to facilitate quality control engineers.
