An analysis of scalar properties of coefficients constructed for fuzzy numbers is one of the methods used to overcome problems resulting from the multidimensional character of such data. A similar approach was employed to prove, on simulation basis, the viability of combining linear and exponential transformations in modelling the dynamics of a field beneath a graph representing membership function in fuzzy time series generated with difference equations. The paper includes descriptions of both the method used to verify the hypotheses and the conclusions arrived at, also those related to the general formula of such a model.
