The term ‘hierarchical fuzzy systems’ is an arrangement of several fuzzy logic units connected in the form of hierarchy. Due to transparency, the fuzzy logic system has been preferred for designing complex systems with large dataset [], but at the same time, the fuzzy logic possesses several functional limitations [6, 7, 9] such as dimensions of rules, dimension of parameters and ...
