Solving Computational Expensive Problems with a Response Surface Surrogate Models

Article Preview

Abstract:

Modern CAE technology is widely used in modern automobile design, engine design and so on. But its computational expense and highly time cost reduce the efficiency of design. The paper studied a respond surface model-based technique for predictive design. Firstly, we study and compare the four kinds of polynomial orders of RSM technique. Then we use Latin Hypercube technique choose enough sample points for approximation. At last, we employed cross-validation error analysis for error analysis. The results of expensive benchmark functions of CEC 2014 tested our predictive methods.
