A material and product audit method for determining the level of quality

This paper introduces a method for evaluating material and product quality. The method is developed based on the normal distribution. For quantitative variable, the method divides the tolerance zones to 3 parts according to normal distribution ±3σ and assigns different scores to tolerance region. Fo...
