Developing acceptance-sampling methods for quality construction

An acceptance-sampling method plays an important role in designing quality-assurance (QA) specifications. It applies statistics to specify the requirements of (1) how many measurements are needed; and (2) how to make an acceptance or rejection decision based on measured data. The key function of the acceptance-sampling method is to guide the decision between accepting or rejecting the quality of the products. The purpose of this paper is to present four acceptance-sampling methods, including (1) variable-single-sampling method; (2) quality-index-sampling method; (3) attribute-double-sampling method; and (4) attribute-proportion-sampling method. In this paper, the theories will be derived and the applications of the four developed quality-acceptance-sampling methods will be described. The advantages and disadvantages of using different sampling methods are compared. The application of the developed quality-acceptance-sampling methods is illustrated using bridge-painting examples.
