非线性多目标Optimization的良分布Pareto集生成方法

A Method for Generating a Well-Distributed Pareto Set in Nonlinear Multiobjective Optimization

S. V. Utyuzhnikov, P. Fantini, M. D. Guenov

摘要:

在多学科优化中,设计者需要找到最优化问题的解决方案,这些问题包括一些通常相互矛盾的准则。这样的问题在数学上与非线性向量最优化领域相关,其中存在能够提供解决方案的许多数值方法。然而,其中只有少数适合于真正的多学科设计在工业中,因为迭代设计周期通常是非常耗时的。这是由于与每个迭代设计周期相关联的时间尺度和计算资源。最近提出的物理编程方法似乎符合工业应用中提出的许多要求。该方法被修改,使其实现更容易和更有效,主要的焦点是完全帕累托集的均匀生成。该方法被用来寻找不同的测试用例的Pareto曲面。

英文摘要:

In multidisciplinary optimization the designer needs to find solution to optimization problems which include a number of usually contradicting criteria. Such a problem is mathematically related to the field of nonlinear vector optimization where there are many numerical methods capable of providing a solution. However, only a few of those are suitable for real multidisciplinary design in industry because an iteration design circle usually is very time-consuming. This is due to the time scales and computational resources associated with each iterative design cycle. The recently suggested Physical Programming Method appears to match many requirements raised in industrial applications. The method is modified to make its realization easier and more efficient, the main focus being the even generation of the complete Pareto set. The method is used to find the Pareto surface for different test cases.
