综合交通枢纽城市级节点布局优化研究

摘要

Under the premise of ensuring the construction of important metropolitan transportation hubs, in order to mathematically model the optimal locations of new metropolitan transportation hubs, this paper considers all the factors that have an impact on the location of metropolitan transportation hubs. An optimization model is developed, which has an objective function of minimizing the distance-based weighted total demand from demanding nodes to candidate nodes, and uses the corresponding relationship between the candidate hub and demanding nodes that are within the service coverage radius of the hub as the constraints. Then, the ILOG is used to solve the model. Finally, a numeric example proves the effectiveness of the model.%为了描述综合交通枢纽城市级节点布局优化问题,在保证重点枢纽城市建设的前提下,考虑综合交通枢纽布局的影响因素,以城市需求点总需求权距离最小为目标,考虑了在枢纽城市节点的覆盖距离内,需求点和枢纽城市候选点对应关系为约束建立了综合交通枢纽城市级节点布局优化的数学模型.采用ILOG对模型进行求解,并结合算例验证了模型的有效性.
