The hierarchical model reflects different awareness from different levels. Combining the property of certainty-uncertainty of set pair and the hierarchy of granularity, a new concept is proposed in this paper, that is granularity pair, which is the definition of granularity in set pair, connects the granular computing and the set pair analysis, pairs with object sets and attribute sets, owns the properties of dynamics, limits and similarity. And a similar hierarchical algorithm is designed about the similarity. The example shows that the algorithm is feasible.
