Problem Definitions

The first step in using the aixd toolkit is defining the problem you wish to apply its methods to. This entails the definition of your designParameters and performanceAttributes.

DesignParameter

Definition: The variables that describe your design, and affect the performance of the design.

Examples: Geometry parameters, material parameters, load parameters, etc.

PerformanceAttributes

Definition: The values you look at to evaluate how good a design is. These performance attributes depend on the design parameters.

Examples: Cost, structural utilisation, structural safety, environmental impact, sun occlusion, etc.

For example for the design of pedestrian bridge your parametric design problem could be defined by the following variables

For this defined design problem we can apply the AIXD toolkit to generate possible bridge geometry vectors for specific performance requests that we make. Or we can use the toolkit to quickly evaluate many design parameter vectors. You can find the whole notebook in the example section.
