A Study on Application of Acceptance Sampling Plan in Processing Control and Monitoring

Abstract

This study examined the use of acceptance sampling technique as an efficient tool for quality assurance in deciding whether a given lot of product is to be accepted or rejected in the market. This study designed two single sampling plans with a sample size of 125 from a lot of size 1350 bread loaves and an allowable number of defectives as 4 and 6 (i.e. c=4 and 6). The result indicated that the probability of rejecting the manufacturers’ product of good quality by the consumers is about 0.371 (producers risk, α=0.371) with the first plan of c = 4. However, the second plan proved more efficient in controlling quality in the industry with c = 6, the producers risk, α=0.235 with the least average total inspection value.  The continuous improvement and review of acceptance sampling plan is important to improve the products quality and ensure continuous customer satisfaction.
