Abstract
Several problems with applications to economics, engineering, environment science, social sciences, medical sciences and other fields cannot be solved by classical mathematical methods since they have inherent difficulties due to the inadequacy of the parametriza-tion tools. Exact solutions for the mathematical models are needed in classical mathemat-ics. If the model is so complicated, then it is not easy to find an exact solution. To handle these kind of situations, many tools have been suggested. Probability theory, fuzzy sets, rough sets and other mathematical tools have their inherent difficulties.
