摘要

The choice of an analytical procedure and the determination of an appropriate sampling strategy are here treated as a decision theory problem in which sampling and analyticalcosts are balanced against possible end-user losses due to measurement error.measurement error is taken here to include both sampling and analytical variances,but systematic errors are not considered.The theory is developed in detail for he case exemplified by a simple accept or reject decision following an analyticla measurement on a batch of material,and useful approximate formulae are given for this case.Two worked examples are given,one involving a batch production process and theother a land reclamation site.
