Abstract:

Graph Morphing is presented to analyze the importance, or sensitivity, of each variable to objective and constraints in optimization model for solid rocket motor design. It is also used to explore the feasible design space and to analyze the robustness of the optimization result. Engineering application proves that Graph Morphing is simple and intuitive to deal with multivariate analysis and visualization problem and have bright future in solid rocket motor design optimization.
