A method to evaluate measurement uncertainty of imprecise neutrons data

The measurement uncertainty is often evaluated by a probabilistic approach, but such evaluation is not always adapted to imprecise measurement data. This paper focuses on the use of the evidence theory to evaluate the measurement uncertainty of imprecise neutrons data. A formula is presented to measure and calculate the measurement uncertainty of imprecise neutrons data coming from imprecise physical sensors and approximate estimations provided by experts, the validity of the formula is demonstrated by two examples. The formula can be applied to precise neutrons data too.
