... strategy's effectiveness. Originality/value To further improve the defects during the forming of irregular beams, a combination of numerical simulation technology and response surface methodology was adopted to establish a response surface model. This model analyzes the influence of univariate...

... This framework relies on a computationally efficient approximation of the constraint and objective functions using a radial basis function model with a linear tail, also called the combined response surface methodology (RSM) in this article. Considering both the code-stipulated constraints and other construction...

... parameters of the selected material model were performed. The optimisation process consists of the method for design of experiment, modelling a response surface and a genetic algorithm. Findings The paper provides comparison of two optimisation processes with different methods for design of experiment...

... approach is adopted to conduct deterministic multi-objective optimization, and response surface is used as meta-model. Reliability analysis is conducted to evaluate the robustness of the multi-objective design optimization. The proposed method is implemented in a step-bottom square cup drawing process...
