Abstract

In production process, quality is directly affected by the degradation of the production machine. Information of products quality may be used as feedback to determine the maintenance policy. As far as is known, research on integration of quality and maintenance widely used quality control with 100% inspection. Many literatures mentioned that sampling inspection is cheaper and easier to be performed than 100% inspection. With the same level of protection, the variable acceptance sampling requires fewer samples and provide more information about the manufacturing process than the attribute data. This paper attempt to integrate variable acceptance sampling and maintenance policy. The variable acceptance sampling model developed based on exact sampling distribution approach under Cpk capability index. If the lot is rejected, 100% inspection will be performed and Cpk will be estimated. The estimated Cpk resulted minimum cost rate will be consider as the treshold for conducting PM.
