Abstract

In sampling inspection, an inspector is subjected to make type I and type II errors which are unavoidable but can be minimized. This paper therefore investigates the effect of these errors considering Single and Double Sampling plans. The Average Outgoing Quality (AOQ) and Average Total Inspection (ATI) are used to measure the impact of the errors considered as anticipated. In order
to measure the impact of these errors by varying the Producer’s and Consumer’s risk with true fraction of defectives (p) from 0.01 to 0.25, it was observed that as the two risk increases, the values of AOQ decrease for p< 0.07; while there was no significant pattern for AOQ for p= 0.07 to 0.09. Furthermore, when p≥ 0.1, the AOQ increases but the ATI increases uniformly. The same trend was also noticed with the Double Sampling plan but with a bit of increase in values around 1% when compared with the Single Sampling plan.
