Abstract

This paper presents a computational tool that has been specifically developed for evidence-based robust design problems. The paper starts with a brief overview of evidence theory and its use in system design. Then a tool to reduce the computational cost of computing the Belief and Plausibility is discussed. The tool is composed of an evolutionary algorithm for worst-case scenario optimization, and a decomposition technique applicable to space systems engineering. Finally, a test case of the preliminary design of a small spacecraft will illustrate the results of the evidence-based robust design optimization in comparison to the margin approach.
