Knowledge Based Systems as Tools in the Systems Engineering Process

This paper explores the use of Knowledge Based Engineering (KBE) methodologies and technologies as tools in the Systems Engineering process. Discussed is progress in the development of a system for automating the complex engineering task of electrical wiring design in aerospace vehicles. Knowledge Based Systems capture rules and engineering knowledge relating to one or more processes in the design phase and are used for design automation, verification, updating and linking product lifecycle phases to ensure compatibility. Effective information management techniques employed in Knowledge Based Systems can lead to greater product integrity, shorter development time and reduced cost. Knowledge Based Systems provide a means of ensuring compliance with requirements and performance parameters. In this example, a system for discovering paths for electrical cables or pipes through 3D structural models is developed. Numerous rules and regulations governing electrical design are automatically validated, and only valid solutions are returned to the engineer for consideration.
