【摘要】 从统计学角度出发,将投影追踪模型应用到互通式立交选型评价体系中,通过遗传算法来实现互通式立交选型方案的模型求解,描述了该方法应用的关键步骤,并指出对于数据量充分、影响因素明确的准真系统,应用实例表明,采用投影寻踪模型进行方案决策更具有客观性．更多还原

【Abstract】 On the basis of building the index system interchange type,the paper puts forward a new method of Projection Pursuit Cluster Model from the angle of statistics．By means of Genetic Algorithm,the paper de- scribes the key steps of Projection Pursuit Cluster Model with an example,and points out that the method is more objective when applied in the decision-making system which contains aboundant data and legible proper- ties．更多还原
