城市轨道交通线网规划是一个复杂的系统工程,其涉及因素众多,仅采用层次分析方法已无法反映判断的不确定性和模糊性;因此应用模糊数学理论优选综合评价和层次分析相结合的方法对城市轨道交通网络规划进行决策评价,并提出了分层模糊优化决策模型。该模型通过多人专家的决策,将各个因素层次化,并且构建模糊矩阵,并计算出各层的权重,采用归一法,经过模糊化运算,最终得出结果,并应用到实例验证了采用此种方法的可行性。
Urban rail transit network planning is a complex system engineering, involving many factors, the use of analytic hierarchy process alone can not reflect the uncertainty and ambiguity of judgments; therefore, the application of fuzzy mathematics theory to optimize the combination of comprehensive evaluation and analytic hierarchy process The urban rail transit network planning decision-making evaluation, and proposed a hierarchical fuzzy optimization decision-making model. The model through the multi-expert decision-making, the various factors of the hierarchy, and the construction of the fuzzy matrix, and calculate the weight of each layer, using the normalization method, the fuzzification operation, the final result, and applied to an example to verify the use of Feasibility of this method.
