... values

Fuzzy values are defined by L-R fuzzy values. Defined as:

$\mu_{ \ensuremath{\tilde{A}} }(x)=(m,\alpha,\beta)=\left\{ \begin{array}{ll} L... ... 0\\ R(\frac{x-m}{\beta}), & if \ x > m, \ \beta > 0\\ \end{array} \right.$

with the characteristic functions L(u)=Max(0,1-u) and R(u)=Max(0,1-u)

... Runge-Kutta-Method

With the Runge-Kutta Method any degree of accuracy may be obtained at each step but the better the accuracy the greater the number of function evaluations required. In this paper the classical 4th order Runge-Kutta Method has been chosen.
