【摘要】：针对山区道路交通网络规划影响决策因素的多样性,综合考虑了技术、经济、环境等方面,建立了基于可持续发展的山区道路选线方案的多目标评价指标体系。根据模糊数学理论与分层优化决策思想提出了多层次模糊运算优化决策模型,即以二级模糊综合评判为框架,首先利用AHP法建立准则层的权重集,熵值法建立指标层的权重集,再根据准则层的指标值运用灰色关联系数法构建模糊矩阵确定评价矩阵,采用二级模糊综合证评判的步骤、算子及评判准则,实现道路交通线网方案的优选,最后应用实例来验证采用此模型方法的可行性。
[Abstract]:In view of the diversity of decision factors affecting road traffic network planning in mountainous areas, the technical, economic and environmental aspects are comprehensively considered. The multi-objective evaluation index system of the mountain road route selection scheme based on sustainable development is established. According to the theory of fuzzy mathematics and the idea of hierarchical optimization decision, the multi-level fuzzy operation optimization decision model is put forward. That is to say, in the framework of two-level fuzzy comprehensive evaluation, the weight set of criterion layer is established by AHP method, and the weight set of index layer is established by entropy method. Then, according to the index value of the criterion layer, the fuzzy matrix is established by using the grey correlation coefficient method. The steps, operators and criteria of the two-level fuzzy comprehensive evaluation are used to realize the optimal selection of the road traffic network scheme. Finally, an example is applied to verify the feasibility of using this model.
