The interconnectedness of knowledge implies the need for a transdisciplinary attitude between humans and computers. This paper proposes a method for requirements and BOMs engineering and their chaining toward CAD models. Agents and multi-agent systems are considered and modelled as transdisciplinary concepts. The cooperative and agent-based platform F-EGEON (Fuzzy Engineering desiGn sEmantics elabOration and applicatioN) is developed for requirements and BOMs engineering. F-EGEON agents structure data into fuzzy BOMs: Fuzzy Requirement BOM (r-BOM), Fuzzy Function BOM (f-BOM), Fuzzy Component (c-BOM) and Fuzzy Parameters BOM (t-BOM). Then, a specific F-EGEON agent generates the Fuzzy cad-BOM to be transmitted to the CAD models. The prospect of equipping intelligent requirements engineering with systems like F-EGEON should not only aim to represent designer proposals, but also to support positive actions or behaviors in the design environment. An intelligent requirement engineering system must be capable of identifying (and even analyzing) false (even imprecise, incomplete, contradictory) statements and biased representations.
