基于不确定多属性计算评价城市交通系统的方法研究

提出了评价内容涉及交通系统功能水平、交通发展协调水平、资源利用水平和环境影响水平4个方面,由31项属性指标构成城市交通系统评价指标体系,并根据评价中残缺的评价判断信息、混合的判断信息反映出的不确定、模糊的实际情况,分别采取辅助矩阵的方法和最小偏差函数的线性目标方法计算确定权重,并采用加权算术平均和组合加权算术平均方法进行各项指标综合,得到交通发展综合评价值。

Study on Evaluating Urban Traffic System Based on Uncertain Multi-attribute Calculation

The essay puts forward the evaluation content involves four parts: function level of transport system, harmony level of transit development, resource utilization level and environmental influence level, the evaluation standard system of urban transit system consists of 31 attribute indices. According to the uncertain and blurry actual status reflected from deficient evaluation information and mixed estimation information, the auxiliary matrix method and linear target method of minimum deviation function are applied separately to confirm the optimization, and the methods of arithmetic weighted mean and combined arithmetic weighted mean are applied for each index integration, thus achieving the comprehensive evaluation value for transit development.
