A Rectifying Inspection Plan Giving LTPD Protection for Destructive Testing

파괴검사시(破壞檢査時)의 계수선별형(計數選別型) LTPD 보증(保證)샘플링 검사방식(檢査方式)

A rectifying inspection plan is considered for the case of destructive testing. Screening inspection for rejected lots is performed by some nondestructive testing which is prone to misclassification errors. Apparent defectives found in the screening process is replaced with apparent good items. The plan provides LTPD protection on each individual lot while the sum of the cost of testing and the cost due to producer's risk at process average quality is minimized. A brief discussion on average outgoing quality is also given.
