Economic Evaluation of ISO 2859 Acceptance Sampling Plans Used with Rectifying Inspection of Rejected Lots

摘要

To conduct acceptance sampling, companies often use plans that are determined by easy-to-use standards. However, these standards do not take quality costs directly into account. Motivated by the case of a Greek company, which uses the Greek equivalent to the ISO 2859 (1974) for the quality control of its incoming raw materials, this article aims to evaluate the single-sampling plans recommended by the latest update of ISO 2859 from an economic point of view. The evaluation shows that the use of standards rarely leads to satisfactory economic results. Therefore, simple rules for the economical use of the standard are provided.
