中缅原油管道贯通对进口原油海上运输成本的影响分析

研究了中缅原油管道贯通对我国进口原油海上运输成本的影响.首先分析了我国的主要原油进口地、进口量和海上运输航线等信息,然后选择了三种不同型号油轮,并调查了其载重量、航速、日租金等数据.以不同型号油轮的运输航次及各条航线上的实际运输量为决策变量,总租金(总运输成本)最小化为目标函数,分别建立了中缅原油管道贯通前后我国进口原油海上运输问题的数学模型,并分别给出了求解方法.最后,根据实际统计数据进行计算,分别求出了中缅原油管道贯通前后我国原油海上运输的总成本,结果显示,中缅原油管道贯通后我国进口原油的海上运输成本将降低4.95%.

Analysis the Effects on the China-Myanmar Crude Oil Pipeline Induced Changes in Import Crude Oil Shipping Costs

This paper analyze the effects on the China-Myanmar crude oil pipeline induce changes in Chinese import crude oil shipping costs.Firstly,we analyze the major crude oil importing countries,the importing quantity,and transport routes.Then we choose three types of tankers and investigate their maximum loads,speeds,daily rents.We use the shipping frequency of every type of tanker and the transport quantity in each line as variables to construct two mathematical models for solving the import crude oil transportation problems before and after the China-Myanmar crude oil pipeline come into use.The goals of the models are to minimize the total shipping costs.We further give algorithms for solving the models.Finally,we do simulation on the actual data.The results show that the shipping costs of import crude oil will be reduced by approximately 4.95%after China-Myanmar crude oil pipeline come into service.
