考虑交通拥堵和低碳经济均衡的内陆港区域物流网络设计研究

The urban logistics network design is the key issue and foundation of reasonable planning and sustainable operation of urban logistics and transportation. With the deployment of inland port and development of high-speed railway, there are numerous impacts on existed logistics network. At this moment, the logistics network re-planning problem and research on the equilibrium condition for urban development have raised to be a novel issue and difficult point at present. However, the existed literature pointed out that there are still short of research on sustainable urban development in logistics network design problem and the related theory are still need to be refining and exploring deeply. Given that, this research deal with the sustainable of urban logistics network, put forward that the traffic congestion of transportation network should be take account into the modeling of logistics network design problem, furthermore, the urban economy equilibrium conditions based on low-carbon emission has been discussed. The topics are: 1.Digging the characters of inland port urban logistics network with data survey and co-relational analysis. 2. applying the traffic flow theory, analyzing the binary roadway capacity when traffic congestion of urban key channel, establishing the integrated design model based on network flow theory, exploring the solving algorithms. 3. With the application of supernetwork theory and variational inequality, constructing the economy equilibrium condition of inland port and cooperated harbor, the economy equilibrium condition of inland port urban cities, and the economy equilibrium condition among multi-modal transportation when minimize the total carbon emission. The result of the study is theoretic innovation with crossing and also is of critical theoretic supporting value for sustainable urban logistics development.

区域物流网络设计是区域物流和交通合理规划及可持续运营的关键和基础。内陆港区域因内陆港部署、高速铁路发展等，原有物流网络受到巨大影响，在此契机进行物流网络再规划，研究区域发展均衡条件，是当今时代的新问题和难点。已有研究表明，物流网络设计问题中面向区域可持续发展的相关理论仍有所欠缺，需深入细化和探索。因此，课题以物流网络的可持续性为基础，提出在构建物流网络设计模型时考虑道路交通网络的交通拥堵，并进一步研究运营阶段低碳条件下区域经济均衡条件，主要研究：1.通过数据调查和相关性分析挖掘内陆港区域物流特性；2.利用交通流理论，分析区域运输干道交通拥堵发生时道路临界容量，并基于网络流思想构建一体化设计模型、开发求解算法；3.基于超网络和变分不等式理论构建低碳排放条件下内陆港与沿海港、区域城市节点间、以及多种运输方式间的经济均衡条件。课题成果既是理论交叉的创新，又是内陆区域物流可持续发展的重要理论支撑。

一带一路战略下，内陆港所在区域已进入交通和物流基础设施兴建黄金期，为避免物流发展带来的货运量增长激发区域原有交通问题和环境问题，以及经济不均衡问题，急需可持续的区域物流资源规划、配置和均衡研究的相关理论支撑。基于此，本项目利用大数据调查方法，首先对内陆港物流网络特性进行调研和分析，对交通拥堵与区域物流情况，交通拥堵与区域物流量等关系进行了相关性分析，开发数据分析和数据挖掘方法，通过大数据融合拟合，获取了道路交通网络中货车的货运-车流装载系数。在此基础上，对考虑交通拥堵的区域货运交通网络设计模型进行构建，并开发求解算法，并对模型实用性，关键参数敏感性进行分析；设计货车出行目的推导矩阵，按出行目的精细化的分析内陆港区域货运碳排放特点和低碳经济特性，在掌握碳排放特性基础上，利用动态博弈理论，研究低碳经济下内陆港区域网络均衡研究和网络设计研究。项目研究中以成渝城市圈实际情况为实际案例，来进行场景设计和分析，并提出了一系列定性对策。本项目将内陆港区域作为一个整体系统，以内陆港区域可持续发展为切入点，利用陆港货运数据为基础予以研究，在内陆港区域物流网络设计问题建模中考虑区域已有运输干道的交通拥堵，并对低碳经济下区域物流网络运作的均衡性进行研究，依托上述研究内容，本项目完成了学术论文17篇，其中14篇已发表，另外3篇已投稿至SCI期刊，参加国内外研讨多次，培养研究生多名，获国家奖学金，优秀研究生标兵等多项，圆满顺利的完成了项目预期目标。项目成果一方面在理论上有交叉和创新探索，另一方面对新时期的新问题有重大理论指导和实践意义。
