Abstract
Fuzzy sets of higher order and higher type form one of the interesting conceptual and methodological pursuits in the development of the fundamentals of fuzzy sets. The objective of this study is to investigate a role of these constructs in the realm of fuzzy modeling. Rather than venturing into detailed algorithmic developments, we highlight key motivating factors behind the use of type-2 and order-2 in fuzzy models, especially fuzzy rule-based models. Linkages between type-n fuzzy sets and hierarchical fuzzy models are discussed. An overall setting of the study concerns granular computing (GC) along with its two fundamental ideas of the principle of justifiable granularity and an optimal allocation of information granularity.
