基于DEA/AHP方法的大运量快速交通方式选择决策

大运量快速交通系统建设对于合理利用城市经济资源、优化城市土地利用布局具有深远意义。但其交通方式的决策过程影响因素众多,传统的决策方法带有较大人为因素。运用数据包络分析(D EA)方法设计了3种大运量快速交通方式(Subw ay、LRT、B RT)的评价模型。针对指标过多的情况,运用层次分析法(A H P)对其进行了加权处理得到综合指标,以便于评价分析。并在D EA求解目标函数中引入相对决策重要因子,弥补了传统D EA方法完全依赖输入、输出指标数据,不能真正反映指标实际重要程度的缺陷。评价实例表明D EA/A H P综合评价方法对于大运量快速交通方式选择决策具有较好的适用性和可操作性。

Decision-making Method for Mass Rapid Transit Mode Selection Based on DEA/AHP

Construction of the mass rapid transit system is of great importance both to rational utilization of the economical resource and optimization of overall arrangement of urban land use.However,the decision-making process is always influenced by some subjective factors.In this paper,the data envelopment analysis method is introduced to design an appraisal model for the decision-making process of three MRT systems(Subway?LRT?BRT).Due to excessive indexes,AHP is used to deal with weighted processing in order to get synthetical indexes to make appraisal simple.Relatively important coefficients are introduced to the target function of DEA to resolve the traditional DEA's dependence on the input-output data completely,which fails to reflect the actual important degree of the indexes.It is testified that the combined method of DEA and AHP is adaptive and maneuverable in the process of decision-making for MRT systems.
