This paper first brings up the conclusion that finished goods inspection by percentage sampling rate of own-brand motherboard products is unreasonable by analyzing the probability of receiving and OC curve. Besides, it analyzes the actual manufacturing process of own-brand motherboard products, and it applies the process average model to estimate the average quality to build own-brand motherboard products quality sampling inspection plan according to the actual level of product quality. This paper provides a scientific theoretical basis for motherboard enterprises to establish a sampling inspection plan and lays the foundation for effective monitoring of product quality fluctuations in the trend in order to improve and enhance product quality. |
