Hyper-radial visualization and its application in launch vehicle design

Considering the deficiency of traditional visualization methods when dealing with high-dimensional multi-objective design optimization, the hyper-radial visualization (HRV) method was studied. HRV provided a lossless visualization way to represent the hyperspace Pareto frontier, enabled designers to realize the complex Pareto set intuitively, and identified a better trade-off design quickly as well. Besides, with the purpose of assisting designers to choose a more specific optimal design solution, the designers' preference was incorporated by the weights and color marks with range-based preferences. A multi-objective optimization design of a sub-orbit launch vehicle was accomplished by HRV, which indicates the HRV method is feasible and efficient for high-dimensional multi-objective design optimization.
