Abstract:

Applying fuzzy relational cognitive maps in dynamic modelling work of the systems involves restrictions deriving from the assumed model parameters. The selection of these parameters depends mostly on abilities of calculating equipment used for the simulation and on the modelling purposes. In most cases it is necessary to balance between increasing the mapping accuracy (which is connected with the calculation time lengthening) and shortening the calculation time (which, in consequence, worsens the accuracy).
Additionally, aiming at the accuracy maximization not always can really improve it, but is always connected with the growing of the computational load. In this chapter the analysis of the intelligent cognitive maps work accuracy in the realization dynamic models is elaborated. As a result of the numerical analysis there was shown the existence of certain optimal parameters of analyzed signals fuzzyfication and connected with them sampling parameters in fuzzy arithmetical operations performed during the modelling processes.
