摘要
针对我国中欧班列的运输现状,解决直达班列不同线路恶性竞争、国内货源分散等问题,从选址-运输路线安排的角度出发,以中欧班列国际网络运输节点为研究对象,建立总成本最小模型,根据离散粒子群算法原理,采用Matlab开发程序对其进行优化求解;实例仿真结果表明:通过该模型及算法得到的全局最优解具有良好的收敛性和有效性;同时可以有效降低中欧班列国际运输网络的物流运作总成本。
According to the status quo of China＇s trains to Central Europe,in order to solve vicious competition of different lines,dispersive goods sources and so on,based on the perspective of location selection-transportation line arrangement,by taking international transportation network node of China-Europe as study object,this paper sets up minimum total cost model. Based on discrete particle swarm optimization principle,Matlab development program is used to optimize and solve it. Simulation results show that the global optimal solution derived from this model and algorithm has good convergence and effectiveness,at the same time,it can effectively reduce the total cost of logistic operation of Sino-Europe transportation network.
