针对集装箱航线密度和腹地货运需求分别建立指标评价体系,建立耦合度模型和协调度模型,并以此来确定系统的耦合阶段和协调等级.以大连港为例,耦合度计算结果验证了耦合度模型应用于港口集装箱航线密度与腹地货运需求之间的可行性.
According to the density of container routes and the freight demand in the hinterland, an index evaluation system is established respectively, and the coupling degree model and coordination degree model are established to determine the coupling stage and coordination level of the system. Taking Dalian Port as an example, the coupling degree calculation results verify that the coupling degree The feasibility of the model applied to the density of the port container routes and the freight demand in the hinterland.
