    摘要:

    針對三維混合布局優(yōu)化設計求解問題，建立了以空間分割方法為基礎的布局模型表示方法,。對圓柱體布局物體和長方體布局物體,，分別對應采用線性八叉樹模型和柵格數(shù)據(jù)模型進行模型轉換,。提出了填充球組的布局模型表示方法,，根據(jù)布局設計要求推導出布局優(yōu)化的數(shù)學模型,。通過構建有向布局序列把TSP問題轉化為布局優(yōu)化問題,，使用適應度函數(shù)來處理布局求解過程中多目標優(yōu)化問題,，運用改進蟻群算法對其進行優(yōu)化計算得到了Pareto最優(yōu)解,。通過對幾種布局設計方案的對比分析,，驗證了布局建模方法和布局優(yōu)化算法的有效性。

    Abstract:

    The layout model representation method based on space partition method was established to solve the 3-D mixed layout design. Linear octree and raster data model were used in conversion model for corresponding cylinders layout objects and cuboids layout objects respectively. The filled ball group was proposed for the layout model representation method, and on this foundation, the mathematical model of the layout optimization problem was obtained according to the layout design requirements. Then the TSP problem was transformed into the layout design problem by establishing directed layout sequence. Meanwhile, the fitness function was applied to deal with the multi-objective optimization in the course of the layout, and the improved ant colony algorithm was put into use to gain the Pareto optimum. At last, the effectiveness of the layout method for modeling and optimization algorithm was illustrated by the comparison of the layout design schemes.
