THE ACCEPTANCE CONTROL COSTS FOR VARIABLE SAMPLING IN CASE OF DISTRIBUTION OF CHARACTERISTIC INCOMPATIBLE WITH ASSUMPTIONS

Abstract

The acceptance sampling is the settlement procedure based on a sample randomly selected from a larger batch of quality in the controlled batch. The inspection can be run in case of variable assessment and attribute assessment. Variable sampling assumes that the parameter of quality characteristic follows the normal distribution. In paper will be presented the procedure of determining the acceptance constant k of acceptance sampling by set sample size and risk of the producer, in the case of distribution of a controlled characteristics significantly different from the normal distribution. In the article the proposed method with the classical method in terms of the generated costs, is compared. It was assumed that in the case of distributions significantly different from normal distribution, the proposed method proves to be cheaper in the application.
