投影寻踪模型评价轨道网规划方案研究

为避免主观评价方法的局限,采用基于样本数据驱动的探索性数据分析原理的投影寻踪模型对轨道网规划方案进行综合评价;给出该模型的建模步骤,并采用实码加速遗传算法实现该模型的求解.采用投影寻踪综合评价模型将轨道规划方案多维评价指标集合成一维投影评价值,根据投影值结果对规划方案进行排序,根据投影方向向量值对各评价指标对综合评价值的贡献程度进行了分析.对综合评价定量判断结果通过与方案定性分析的对比,表明该方法符合实际决策要求,模型可靠适用.

Study on Projection Pursuit Model for Evaluation of Urban Rail Network Planning Project

This paper adopted projection pursuit model,which is based on explorative date,analysis principle of driving of sample data,to evaluate the planning project of rail network.The modeling steps are presented,and real coding based accelerating genetic algorithm is used to solving model.This paper used projection pursuit model to avoid the deficiency of subjective evaluation method,and aggregate the rail network planning project's multi-dimensional evaluation indexes to one-dimensional projection evaluation,the...
