Object Oriented Approach in Fuzzy Arithmetic Using Parametric Representation of Fuzzy Numbers

Parametric representation of fuzzy numbers (PFN) with derived methods for performing fuzzy arithmetic proves to have better accuracy and similar computational speed to using triangular fuzzy numbers (TFN). These fuzzy numbers (PFN) can be considered a special case of triangular fuzzy numbers (TFN) as they have three additional parameters and their methods for arithmetic operations are further specialized in regard to TFNs. In the paper object oriented approach and achieved results applied to the topic are presented. Generally object oriented approach provides higher abstraction, which makes the problem better apprehensible and further extensible in more specialized cases. The other benefit of this approach is reusability of created modules and rather simpler programming code formalization. This paper draws from rich conceptual means that provides object oriented software tools. In the paper virtual mechanism, polymorphism and information hiding are the main features used for object oriented approach in this topic
