Comparison of consumer’s risk quality for different sampling plan corresponding to adjacent sample size

Abstract: In some practical cases, people want to know the risk difference of the sampling plan corresponding to adjacent sample sizes. This paper mainly discusses the difference of consumer’s risk quality for different sampling plan for both the sampling procedures for inspection by attributes and by variables with adjacent sample sizes. What’s more, we gave the analysis of consumer’s risk quality in different lot size and sample size. The results show that in the sampling procedures for inspection by attributes the exact lot size within the same lot range has little effect to the consumer’s risk quality. The key factor affecting the acceptance probability is the acceptance number. In the sam-pling procedures for inspection by variables, as the sample size increases, the consum-er’s risk quality decreases.
