1. Introduction
Fuzzy signatures can model complex structured problems with the help of hierarchically structured vector valued fuzzy sets, and a set of aggregation functions [3]. The hierarchically structured vector valued fuzzy sets represent the degree of relationship of the attributes of the object. The set of aggregation functions map, from lower branches to the higher branches, the different universes of discourse of the hierarchical fuzzy signature structure. Further, these aggregation functions are non-homogenous. We argue that these properties help fuzzy signatures to model problems similar to the nature of human approaches to problem solving [3].
