摘要
为了使地下快速路集散点选址满足需求点的要求,针对地下快速路集散点选择模型,考虑设施服务能力等条件的限制,进行了模型的改进。采用定性和定量分析相结合的方法,在以集散效率最大化为目标的集散点选择模型的约束条件中,加入了备选集散点容量限制的约束,对集散点选择模型进行了改进,通过一个算例对结果进行分析,并验证了改进后模型的可行性。研究结果表明:改进后的集散点选择模型能够求得最优解,获得的最优布置点分散,能够满足最大范围的需求并引导需求的空间转移。
In order to make urban underground expressway depot meet all needs, aimed at depot choice model of underground expressway, considering the limitation of the service capability, research on improved depot choice model was carried out. Based on quantity and quality analysis, capacity restraint was taken into account in the depot choice model of underground expressway for the purpose of maximizing the depot efficiency. An example was presented to illustrate the feasibility of the improved model. The results show that the improved model can get the optimal locating of passageways which are dispersible in the whole network, and the locations can meet the demands of the maximum zone and lead the demand to transfer in extended space.
