Two kinds of mathematical model, namely, minimum freight linear programming model and goal programming model were used to study and analyze the problem of the lines 'capacity cooperation. 论文主要运用航线规划的最小费用线性规划模型与多目标规划模型进行航线运力合作问题的研究。
According to the vehicles arrangement for an open-pit mine production, the mathematic model of the minimum of total freight volume is firstly established. 针对露天矿生产的车辆安排,首先建立并求解总运量最小的数学模型,在得到最优解的情况下,选择一个合适的算法得到相应的最少卡车数。
Three models were built to solve the problem. The targets of the models were minimum delivery time, least delivery times and minimum transportation cost under the condition of freight discount. 根据p?中位问题的建模思路,依据航班时刻和货运量,分别建立了最少配送次数、最短配送时间和运费有折扣情况下的最低运输成本的优化模型,并对模型进行求解。
