To define uncertainty, we must first define the measurable quantities and then the measurable space. This is followed by the uncertain variable and finally the uncertain space. Meanwhile, the operators for these sources are also defined.eninfo:eu-repo/semantics/closedAccessBorel SetsDistributive FunctionMeasurable SetUncertain VariableBook Chapter3813902-s2.0-8520290125910.1016/B978-0-443-16147-6.00027-X
