【 摘 要 】

In this paper, a computer implementation to evaluate the arithmetic operations on two fuzzy numbers with linear membership functions has been developed. The fuzzy arithmetic approached by the interval arithmetic is used here. The algorithm of the developed method with a numerical example is also provided. Using this method four basic arithmetic operations between any two TFNs can be evaluated without complexity.Keywords:Fuzzy arithmetic, Fuzzy number, Membership Function, Interval arithmetic, α - cut.
