基于驾驶员偏好的最优路径选择

现实生活中，驾驶员往往依据自身偏好来选择路径，对不同的路径属性有不同的要求，且对其属性值存在一个可接受范围，而不是一个精确值. 本文对存在驾驶员偏好的最优路径选择问题进行了研究，提出了一种能够综合反映驾驶员偏好的最优路径选择方法. 首先基于可能度和区间数相离度的多属性决策方法，建立驾驶员偏好与路径属性总偏差最小的优化模型，并解出路径属性权重；其次算出各路径的综合属性值，建立路径间的可能度矩阵及其排序向量，据此选出最优路径；最后以算例进行验证，结果表明本文给出的路径选择方法具有很好的可行性和适用性.

Optimal Path Selection Based on Driver’s Preference

Drivers often make route choices according to their preference in our real life. They have different requirements for different path attributes whose values are in the acceptable range rather than a precise value. In this paper, the problem for optimal path selection with driver’s preference is studied and optimal path selection method is put forward to comprehensively reflect preference. Firstly, considering the multi-attribute decision-making method based on possibility degree and interval number’s deviation degree, the author presents an optimization model by minimizing total deviation of driver’s preference from path attribute value and counts out the path attribute weight. Secondly, depending on obtaining comprehensive attribute value of each path, possibility degree matrix and ordering vector are built between paths and the optimal path is found. Finally, an example is given to verify that the path selection method has good feasibility and applicability.
