COMPARISON OF ROBUSTNESS INDEX OF THE OBJECTIVE FUNCTION IN ROBUST OPTIMIZATION
The robustness index of the objective function is explored for robust optimization.The robustness of an objective function seeks an insensitive design although there are variations on the design variables or the parameters.Based on this viewpoint, a variety of robustness indices on the objective function have been developed.Nevertheless, the application of the index is not prevalent yet due to some limitations.Therefore, it is important to identify the characteristics and drawbacks of the existing robustness indices.In this paper, a comparative study on the robustness index of an objective function is conducted to verify the characteristics and the limits.To reach this purpose, a mathematical example is utilized.The example has both a deterministic optimum and a robust optimum.Then, evaluation and analysis of the robustness indices are conducted by using an example.Consequently, useful information about each index is obtained.Also, based on the comparison, some important issues for robustness of the objective function are discussed.
