Optimum Life Test Sampling Plans for Products Sold Under Warranty: A Cost Function Approach

Abstract

At any manufacturing unit when a lot or batch of raw material is received, it goes through quality check. Doing quality check for each and every item of the lot can be both time consuming and costly. If in case the quality is destructive (eg: testing light bulbs) by nature, then testing every item is not an idea to be pondered upon. but quality also shapes beliefs of the customers and hence can have a huge impact on sales. Therefore, the received lot cannot be passed without any quality check either. In order to solve the aforementioned problem, manufacturing and production industries employ the technique of acceptance sampling.
