Abstract: In the quality inspection practice of the consumer electronics industry, MIL-STD-105E sampling table is viewed as the basis for sampling plans. This traditional quality inspection plan determine the sample size and reject rule based on the size of lot, consumer’s and producer's risk and average quality level (AQL). Traditional sampling plan does not consider internal and external quality costs. However, quality costs were considered in many previous researches, but the comparison between traditional and economical design of single sampling plan is rare from now. This paper discusses the sampling test before the receiving inspection which is vendor simulated buyers. Includes the costs of inspection, rework, replacement, and external failure cost are considered. We compare the quality economical design with traditional single sampling plan under the total quality cost. This paper can be regarded as a reference for future studies and practical applications.
