Measurement uncertainty models

摘要

For decades, experimenters, engineers and statisticians have developed several types of measurement uncertainty models. This paper explores the origins of some of the most common models, their strengths, their weaknesses and the reasons for using them in particular situations. Models considered include the U. S. Air Force standard model, the American Society of Mechanical Engineers (A. S. M. E.) standard models (c. 1985), the International Standards Organization model and the proposed simplified A. S. M. E. uncertainty model which is in harmony with the ISO model.
