Robust design from systems physics

ORAL

Abstract

Ensuring robust outcomes and designs is a crucial challenge in the engineering of modern integrated systems that are comprised of many heterogeneous subsystems. Coupling among heterogeneous subsystems leads to the complex response of design elements to changes in whole-system specifications. Here, we show that the response of design elements to whole-system specification changes can be characterized, as materials are, using strong/weak and brittle/ductile dichotomies. We find these dichotomies emerge from a mesoscale treatment of early stage design problems that we cast in terms of stress--strain relationships. We illustrate the use of this approach with examples from naval engineering, however our approach is immediately applicable to a broad range of problems in integrated systems design.
