Abstract

Aerodynamic multi-objective optimization problem (AMOP) is common in aerodynamic optimization design (AOD). Multi-Objective Evolutionary Algorithms (MOEAs) are popular to solve AMOPs since they can obtain a set of solutions called Pareto optimal in a single run. Since numerically evaluating the objective of AOD is generally computationally expensive and time consuming, improving the convergence performance of MOEAs and focusing the computational resource on the solutions that the decision maker (DM) most interested in are two important aspects to solve AMOP better. An improved multi-objective evolutionary algorithm based on decomposition using a combined operator is used to improve the convergence performance. Several methods of solving AMOP considering the DM's preference are also discussed which focus the computational efforts on the Pareto solutions that suit the DM's preference better. Multi-objective test functions and aerodynamic optimization design of airfoil is tested. The results show that the improved algorithm is capable to solve AMOPs with user preference, and converge faster than the original algorithm.
