Abstract :
Truly qualitative modelling of qualitative dynamic systems is a delicate issue in a sense that even when one uses a "qualitative modelling tool" one often end up adopting quantitative model approaches in disguise. In this paper, we use rule based fuzzy cognitive maps to obtain and simulate a qualitative model of an economic system.
