Abstract :
This paper focuses on the comparison between rule based cognitive maps and fuzzy cognitive maps. The paper shows FCM limitations to represent non-monotonic non-symmetric causal relations, presents results that exhibit the stability of RBFCM in systems where FCM is not stable due to its non-fuzzy inherent nature and presents RBFCM potential to model qualitative real-world dynamic systems
