In this paper, we present a fuzzy extension of inheritance hierarchies. The purpose of this extension is to provide a more refined construct that facilitates the representation of relations among concepts under uncertainty conditions. The extension is done in two steps. First, the synonymy relation is incorporated in the inheritance hierarchy, resulting in a new construct denoted a concept-network. Second, the relations of the concept-network are fuzzified, yielding a new construct denoted a fuzzy concept-network. We show how a fuzzy concept-network can be interpreted as a collection of inheritance hierarchies. Thus simplicity, which is an important characteristic of inheritance hierarchies, is preserved. We discuss how fuzzy concept-networks can be used in the application of reusable software retrieval in object-oriented software development.
