This paper describes concepts to support the application of descriptive functions using artificial intelligence technologies. Descriptive functions are typically used in the system design phase to describe and specify the system behavior. In a model‐based systems engineering approach the system functions, their dependencies, and the allocation to the technical solution are typically documented in system models. Descriptive functions have a fuzziness that is beneficial in the solution finding process but also challenging in terms of development efficiency. To support development teams in formulation and working with descriptive functions in system design, and verification and validation phase several concepts with the use of artificial intelligence technologies are discussed.
