摘要
基于投影寻踪算法的基本原理和求解过程,提出互通立交方案设计综合评价方法,该方法直接从待评样本本身寻求各评价指标的客观权重,避免了主观评价法评价指标权重的确定存在着主观依赖性、评价结果受到人为赋权的干扰问题。采用实码加速遗传算法对投影指标函数进行优化,求解最优投影方向向量,可有效地解决高维数据全局寻优的难题。
Comprehensive evaluation method for interchange project is built on projection pursuit technique. The method can determine directly the index objective weights result from sample data themselves, which can avoid the subjective negative impact on conclusion in other evaluation models. Real coding based on accelerating genetic algorithm（RAGA）is proposed and applied to the model optimization, used to search for the optimal projection directional vector, which can deal with effectively global optimization problem with various restriction conditions.
