摘要
求解多目标优化问题的方法一般是先求出问题的非劣解,再从许多非劣解中选取好解。本文在已有非劣解的情况下,提出了各非劣解相对于理想解的的隶属度公式。运用模糊贴近度的概念从众多的非劣解中找出最贴近于理想解的最优解。该方法运用于悬索管桥结构参数的多目标优化设计中,得出了非常满意的设计方案。
Ordinary , the methods to soluting multi-objectives optimal questions are always to find many non-inferior solution of the questions, then to choose a fine solution from them. To find many non-inferior solutions, this article provides a formulation of the grade of membership of the branch objectives in varion of non-inferior solution which are subordinate to the branch objective in ideal solution, then getting a non-inferior solution or. a optimal solution which is to full extent close to the ideal solution from many non-inferior solutions by using the concept of fuzzy closeness degree. In this article, the method is used to multi-objects optimal design of a suspended-pipe bridge structure parameters,and we get a very complete design parameters.
