综合运用Logit模型和DDSUE模型,研究了上海港集疏运系统中的路径流优化问题,对连接货源地与目标港区之间的所有主要路径进行合理的流量分配,并在路径初始流量为零和港口管理者可以及时、准确地将城市道路交通数据传递给运输者的前提下,通过具体实例模拟了货物从货源地到港口的动态分配的整个过程,证明了算法的实用性.
Path flow optimization problem is studied in port collection and distribution system using Logit and DDSUE models to make a reasonable path flow allocation among the main paths connected to supply region and the target port. The whole process of dynamic allocation from the catchment to the port is simulated at the premise of zero initial path flow and timely passing road traffic data to the transporter, which demonstrates the feasibility of the algorithm.
