Selection of Single Sampling Plan on the Basis of AQL, AOQL. ATI and I.TPD: A Case-Study on Haleeb Foods Ltd., Lahore

Abstract

The Haleeb Foods Limited (HFL) is taking care of quality of production by using acceptance sampling procedures. To check the validity of sampling plan adopted by HFL, 30 sampling plans are compared with respect to AQL, AOQL, ATI and LTPD. The results and conclusions show that quality is always towards an improvement trend. The technology is no more the superiority as it is accessible to every one. Investigation and reduction in variations are key to process improvement. For HFL a single sampling plan with N=2700, n=30 and c=1 is suggested, for better quality products. The proposed sampling plan will provide decrease in AQL, AOQL & LTPD by 11.36%, 10.83%, & 9.74%, respectively. The 6.35% increase in ATI is negligible. Thus, the proposed single sampling plan shows improvements with respect to producer’s risk, consumer’s risk and lot tolerance percent defective for P10.
