ABSTRACT
Ignorance and uncertainty types as described in Chapter 1 were used to develop methods for data and information encoding and expression, and uncertainty-based synthesis of information as discussed in Chapters 2 and 3, respectively. Engineers and scientists often need means to quantify uncertainty. Uncertainty measures can be viewed as similar to scales or measures used to quantify physical quantities, such as temperature, pressure, or dimensions; however, they are unique in that they measure conceived or abstract notions rather than a physical quantity. The objective of this chapter is to present methods for measuring uncertainty contents in the form of basic models.
