Summary:
Multilevel design spans physical scales and disciplines, with interacting variables and underlying phenomena that span from systems to components to material levels. We are establishing a set-based method for collaborative, decentralized design exploration of these multilevel systems. The method facilitates distribution of design activities while reducing iteration among designers and achieving satisfactory system-level solutions. As part of the method, designers communicate across levels and disciplines via approximate models and design space mappings that represent sets of satisfactory design solutions. Specifically, we use Bayesian network classifiers to create a map of the design space at each level and/or discipline. These maps can be intersected to find satisfactory system-wide solutions, and they provide a statistical foundation for stochastic search and design space exploration. In recent work, we are utilizing these techniques to design metamaterials hierarchically across multiple levels of cascading analyses.
