Background & Aims: Uncertainty is a state in which the knowledge of a person or persons is limited and full knowledge of the state or result that has been achieved or is not possible. Macroeconomic uncertainties create an uncertain environment for investors and make it impossible for investors to make decisions about future investments more efficiently and with more confidence, and they may suf...

Considering that excessive sample data points are needed in the probabilistic method, in this paper, two non-probabilistic methods are proposed for uncertainty quantification and propagation analysis based on the Gray mathematical theory and the information entropy theory. These two methods can give the interval estimation of true value from the framework of non-probabilistic theory under the c...

When breast screening began in the UK, such was the uncertainty concerning the benefi ts and harms of detecting ductal carcinoma in situ (DCIS) that national guidelines specifi ed an upper limit as well as a lower limit for detection by individual screening centres. This was only changed when an association was shown between DCIS detection and small invasive cancer detection in the National Hea...

Fuzzy set theory has been proposed as a means for modeling the vagueness in complex systems. Fuzzy systems usually employ type-1 fuzzy sets, representing uncertainty by numbers in the range [0, 1]. Despite commercial success of fuzzy logic, a type-1 fuzzy set (T1FS) does not capture uncertainty in its manifestations when it arises from vagueness in the shape of the membership function. Such unc...
