This methodology hierarchically refines (or reduces) a large initial design space through a series of multiple-objective optimizations, until a fully specified design is obtained. This contrasts with the traditional approach to design optimization which involves picking a fully specified design from the space of possible designs and then iteratively modifying its specifications to maximize the performance. The HIDER methodology uses an adaptive modeling approach that combines machine learning and statistical techniques for developing fast empirical models with different levels of detail and evaluation speeds. These models are used for multiple-objective optimization at different stages of the design. The use of layered models enables HIDER methodology to be used at different stages of parametric design, including early stages when design specifications are not complete. This methodology also supports multiple perspectives in concurrent design because it provides means for transforming models from these different perspectives into a uniform representation, as well as facilitating decision-making with respect to multiple competing objectives. This paper presents the HIDER methodology with an example in the parametric design of a diesel engine.
