Abstract: A system to leverage functional knowledge by a design tool in an engineering project includes a functional knowledge repository created by modeling a plurality of requirements of the engineering project and a requirement and space planning tool interfacing between the functional knowledge repository and the design tool. The requirement and space planning tool includes a requirements wizard to capture the plurality of requirements of the engineering project, a designer graphical user interface to display a preliminary design representing the plurality of requirements and functionality to modify the plurality of requirements, and a design tool interface to transfer the plurality of requirements and the preliminary design between the design tool and the functional knowledge repository.

Abstract: A method of leveraging functional knowledge in an engineering project includes obtaining a first requirement of the engineering project, creating a first attributed entity, associating the first attributed entity with the first requirement to obtain a first attributed requirement, obtaining a second requirement of the engineering project, creating a second attributed entity, associating the second attributed entity with the second requirement to obtain a second attributed requirement, defining a plurality of constraints based on at least one of the first attributed requirement and the second attributed requirement, applying the plurality of constraints if one of the first attributed requirement and the second attributed requirement is modified, and providing notice if at least one of the plurality of constraints is violated.
