Specifying vague requirements with a fuzzy logic based modeling framework
J. Lee · 2002
Proposes a faceted requirement classification scheme for analyzing heterogeneous requirements. The representation of vague requirements is based on the canonical form in test-score semantics and an extension of the notion of soft conditions. The trade-offs analysis of conflicting soft requirements is conducted using fuzzy multi-criteria optimization techniques. The proposed approach provide a framework for formally modeling vague functional requirements.>
