基于效用理论的多目标路径选择模型

Multiobjective Path Selection Model Based on Utility Theory

首先分析了影响驾驶员路径选择的基本要素,基于效用函数理论建立了多目标路径选择模型;在消除量纲对路径选择的影响的基础上,提出了逼近理想路径、远离负理想路径的最优路径判别方法;最后,通过计算每条路径的优劣指标值对多条路径进行排序,且方法易于编写成计算机程序语言,对于大量数据信息下的路径选择模型,可以迅速找到最优路径。

This paper firstly analyzes the basic factors affecting the path selection of the drivers, sets up multiobjective path selection model based on utility function theory, proposes the discriminating method for the optimal path of approximating ideal path and far-from negative ideal path on the basis of the eliminating of the influence of dimension on the path selection, and finally ranks multi-path by calculating the good and bad value of each path. This method can be easily written into computer program language and can rapidly find the optimal path for the path selection model under massive data information.
