Neural Network (NN) is one of the most commonly used method in credit scoring. On the other hand Fuzzy Logic (FL) cannot be used alone in credit scoring due to lack of learning ability. However this is possible in hybrid models where NN and FL are used together. This study…

In this paper we obtain a fuzzy expression corresponding to the final value of an annuity of variable terms in fractional arithmetic progression. Considering the fuzzy interest rate with structure of triangular fuzzy number, we apply this expression to the calculation of the final value in pension funds in view…
