abstract

The design of complex engineered systems is one of the great challenges currently facing designers. Beyond addressing the obvious difficulties stemming from system complexity, designers must also consider that such systems will likely evolve within their service lifetime. As future environments are often unknown, designers must create systems capable of evolving in-service to meet unforeseen requirements. Previous research exploring the concept of service-phase evolvability has indicated that design excess is a critical factor enabling such change. This paper explores how information available from current techniques in the design literature that focus on system change can be expanded and synthesized to map excess within a component and within a system. Examples are presented where information from High-Definition Design Structure Matrices and functional models are used to complete this mapping. The goal of this paper is to serve as the foundation for quantifying design excess in future work.
