Robust design of coupled sub-systems using visualization

In this paper, the paradigm of Visual Design Steering (VDS) is applied to multi-objective optimization problems involving coupled sub-systems where uncertainty exists. VDS was applied to improve the efficiency and reliability of solutions, and more importantly provide a means for capturing and enabling designer insights. The visualization method created, named Brick Visualization (Brickviz), is an abstract way of representing multi-objective problems with coupled sub-systems. The visual tool allows a designer to examine regions of feasibility with differing uncertainty models available to approximate a different coupled sub-system. A designer can quickly assess promising regions (bricks) and then enter these regions for even more detailed information. The method creation is presented along with the results of test cases.
