摘要:

以“低碳运输”为背景,综合考虑单位碳排放总量的约束,以及单位运费的不确定性,对快捷货运方式的选择展开研究.首先,以快捷货运总成本最小为优化目标,以时间和单位货物碳排放总量为约束条件,通过引入三角模糊数,建立快捷货运方式协同优化模型.然后利用Matlab的Yalmip工具箱进行模型求解,并以兰州到北京为背景设计算例.最后,通过调整单位碳排放总量及时间约束,对比分析该约束对快捷货运方式选择及总成本的影响.研究结果表明,在满足运到时限的前提下,合理的选择运输方式对于碳排放的控制具有重要意义.

Abstract:

Considering comprehensively constraints of total carbon emissions per unit and the uncertainty of unit freight, this paper aims to probe into the mode selection of express freight transportation based on the background of “low- carbon transportation”. First of all, by introducing the triangular fuzzy number, the cooperative optimization model of express freight transportation is established, taking the minimum total cost of express freight as the optimization goal, and taking the time and total carbon emission of unit goods as the constraints. Then applying Yalmip toolbox in Matlab to achieve the model solution and taking Lanzhou to Beijing as the background design example. Finally, by adjusting the total carbon emission of unit goods and time constraints, the effects of them have had on express freight mode selection and cost are compared and analyzed. The research results indicate that, under the condition of meeting transit period of freight, reasonable selection of transportation mode is of great significance for the control of carbon emissions.
