摘　　要：面向复杂动态条件下的路径选择过程,面向驾驶人的个性化需求,构建个性化指标集,引入驾驶人心态指标函数,将定性、模糊的区间指标值定量化,从而构建路径决策矩阵;最后,基于客观自主式决策方法,将客观评价对象当作有思考能力的个体来全面参与路径选择过程,对可行路径进行优化评价,获得最优路径。研究结果表明:个性化路径指标集的构建降低了问题的复杂度,减小了计算规模,基于驾驶人心态指标,可以将模糊化的区间路径评价指标定量化,在表达驾驶人个性化特点的同时,进一步简化了路径决策过程的复杂性;该方法既尊重了客观可行路径的本身物理特征,又充分表达了驾驶员的主观个性化需要,从而使得所选路径更为合理;仿真算例验证了本文算法的有效性。Facing the condition of the complex dynamic path selection process,give full consideration to the driver the personalized demand,a kind of the personalized optimal route selection based on the objective and autonomic decision method is proposed.First of all,for the driver＇s personalized demand,individuation index set is constructed;Introduce the driver attitude indicator function,then index quantitative,qualitative and fuzzy interval to build path decision matrix;Finally,based on the objective and autonomic decision method,the objective evaluation objects as a thinking ability of individuals to fully participate in the routing process,optimize the feasible path,get the optimal path.This method reduces the computing scale,the driver can be based on the mentality of index,fuzzy interval path quantitative evaluation indexes,in the expression of driver＇s individual character at the same time,further simplifies the complexity of the decision process;The method not only respect the objective and feasible path itself physical characteristics,and fully express the subjective personalized needs of the driver,so as to make the selected path is more reasonable.The simulation examples verify the effectiveness of the algorithm in this paper.1tab,16 refs.
