: In the pseudo-MAP optimization method, the vital task is to set nine characteristic operating points for optimization. These points distribute in near-surge, medium, and near-choke conditions respectively at each low, medium, and high characteristic rotating speeds in the compressor MAP. Their performances (efficiency and flow at the medium and near-choke points, efficiency, and pressure ratio at the near-surge points) are set as optimization objectives, while the compressor parameters are screened by 2<sup><i>k</i></sup> factorial analysis. Then, the appropriate model is constructed via DoE and RBF. The optimal compressor structure is obtained by conducting a multi-objective optimization with 18 optimization objectives. All the involved test plans and data processing methods are provided in the paper and the supplementary Tables InternalRef removed–InternalRef removed.
