我们提出了一种解决多目标优化问题的新方法。我们的方法使用称为量消除的符号计算。根据实验数据,我们首先为每个目标函数建立一个近似多项式模型,然后求解与这些函数相关的一阶公式以找到可行区域,其中包含有关帕累托最优前沿的信息。我们的方法比一次仅返回一个最佳点的经典数值优化方法具有优势。此外,通过在公式中引入一个调整点和一个限制参数范围的新变量,我们可以可视化目标函数的局部行为。这个想法为我们带来了衡量生产公差稳健性的新标准。我们还展示了如何将我们的方法应用于硬盘滑块的设计问题。
We propose a new approach to tackling multi-objective optimization problems. Our method uses symbolic computation called quantier elimination. From experimental data we rst make an approximated polynomial model for each objective function and then solve a rst-order formula related to those functions to nd the feasible region, which contains information on the Pareto optimal front. Our approach has an advantage over classical numerical optimization methods that return only one optimal point at a time. Furthermore, by introducing into a formula an adjusting point and a new variable that restricts the parameter ranges we can visualize how the objective functions locally behave. This idea leads us to a new criterion for measuring the robustness against production tolerance. We also show how our methods are applied to the design problem of a hard disk slider.
