15.4 Structure of the Tradespace

Pareto analysis is an important part of tradespace analysis, but it is by no means sufficient. There is a great deal to be learned from looking at the structure and features of the tradespace as a whole, rather than focusing only on the fuzzy Pareto frontier. Sometimes a trade space just looks like a cloud of points. However, most tradespaces have some structure; they have a shape. They have features such as holes, subgroups, and fronts. These are due to factors such as discrete metrics, different dynamic ranges of metrics, and physical laws limiting certain metrics.

A common feature of tradespaces is the presence of clusters—that is, the accumulation of architectures in relatively small regions in the objective ...
