Improved group acceptance sampling plans for the gamma distributed items
| STATISTICA & APPLICAZIONI - 2011 - 2
In this paper, a time truncated group acceptance sampling plan (GASP) is designed under the Gamma
distribution. The present plan is modification of the existing plan to reduce the number of
groups/sample size. The plan parameters are obtained by satisfying the producer’s risk and consumer’s
risk (two points approach) for specified values of mean ratio and number of testers. The single
point approach is also used to find plan parameters such as number of groups for specified values
of acceptance number and experiment time. The extensive tables, graphs and examples are given
for illustration purposes. The advantage of the proposed plan discussed over the existing plans.
