Real-world problems in decision analysis, economics, optimization and other fields are characterized by fuzzy and partially reliable information. In this regard, Prof. Zadeh suggested the concept of a Z-number, as an ordered pair Z = (A, B) of fuzzy numbers A and B, the first of which describes a linguistic value, and the second one is a fuzzy value of probability measure of the first one, playing...
The theory of usuality suggested by L.A. Zadeh is widely used in many areas including decision analysis, system analysis, control and others where commonsense knowledge plays an important role. As a rule, this knowledge is imprecise, incomplete, and partially reliable. The concept of usuality is characterized by a combination of fuzzy and probabilistic information. Formally, it is handled by possibilistic-probabilistic...
