Abstract
The objective of this study was to determine whether altering the coal sampling program by differing sampling decision rules would result in tighter quality control of a preparation plant's clean coal output, and if so, to determine whether it would be economically feasible. The basic consideration is the product gain possible and the increased cost of sampling and analyses. To aid in the analyses, a computer model was developed. By applying systematic decisions to sampling frequencies, based on results of previous sample analyses by use of the markovian chain theory and other statistical and mathematical techniques, new sampling schemes can be modeled and compared using economic considerations. Through this method, it may be found that for a typical plant, overall economics can be improved by altering the sampling program, most likely by requiring additional sampling. Effects of premiums and penalties, as well as sampling and analytical costs on plant economics, are included.
