Our paper to develop some useful analytical tools for the foundations of Uncertainty Measures. Because we need to obtain new ways to model adequate conditions or restrictions, constructed from vague pieces of information. For this, it is necessary to classify more efficiently the distinct types of measures; in particular, the fuzzy measures. Now, we complete this study by the analysis on Entropy and other Measures of Uncertainty, with their relationships. So, we attempt to go on, advancing by this paper.
