AN INFORMATION-ECONOMICS APPROACH TO QUALITY-CONTROL ATTRIBUTE SAMPLING

The information-structures model provides a theoretical framework for assessing the normative value of information. This paper applies the i nformation-structures model to quality control attribute sampling, whi ch is usually based on industrial and military standards that do not i nvolve economic considerations or meet cost considerations. Common qua lity control terms, such as AQL, LTPD, and operating characteristic cu rves, are shown as special cases of the information-structures model. Theorems involving dominance among various quality control plans are p roved. The Blackwell Theorem on the 'generally more informative' relat ionship is modified for this application.
