【摘要】 在给出公交线网优化的约束条件和目标函数的基础上,根据物元分析理论和运筹学中的理想点法,通过定量分析在得到标准指标决策矩阵、正负理想方案决策矩阵和方案指标矩阵距离的情况下,建立了公交线网优化的物元分析模型,并通过方案指标矩阵距离大小来判别公交线网优化程度.在用极值法确定目标函数权重的基础上,对模型进行了定量求解.实例分析表明,该模型能够较好地对公交线网进行优化调整,优化结果更为科学合理、符合实际需要.更多还原

【Abstract】 On the basis of considering each factor of urban traffic line network,the optimization function expression and restricted condition of urban traffic line network were set up.Based on matrix theory in extension and TOPSIS in research operational,the extension ideal method for the optimization of urban traffic line network was set up by quantum analysis.Applied result indicated that the method is simple and practical and the result is believable.更多还原
