    摘要:

    針對(duì)三維混合布局優(yōu)化設(shè)計(jì)求解問(wèn)題,，建立了以空間分割方法為基礎(chǔ)的布局模型表示方法。對(duì)圓柱體布局物體和長(zhǎng)方體布局物體,，分別對(duì)應(yīng)采用線性八叉樹(shù)模型和柵格數(shù)據(jù)模型進(jìn)行模型轉(zhuǎn)換。提出了填充球組的布局模型表示方法,，根據(jù)布局設(shè)計(jì)要求推導(dǎo)出布局優(yōu)化的數(shù)學(xué)模型,。通過(guò)構(gòu)建有向布局序列把TSP問(wèn)題轉(zhuǎn)化為布局優(yōu)化問(wèn)題，使用適應(yīng)度函數(shù)來(lái)處理布局求解過(guò)程中多目標(biāo)優(yōu)化問(wèn)題,，運(yùn)用改進(jìn)蟻群算法對(duì)其進(jìn)行優(yōu)化計(jì)算得到了Pareto最優(yōu)解,。通過(guò)對(duì)幾種布局設(shè)計(jì)方案的對(duì)比分析，驗(yàn)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.
