中国成品油需求仿真系统及仿真模拟研究

利用系统动力理论和成品油供需分析建立了我国三类成品油需求仿真系统,本系统分为三个子系统,即汽油需求子系统、煤油需求子系统和柴油需求子系统.系统模拟实践表明,在假定国际原油在高位平稳运行、国内经济快速发展、各类主要用油机具燃油经济性不发生变化等假设条件下,三类成品油供需呈上涨趋势且比较平衡,但均体现出供应紧张趋势;三类成品油需求比例比较稳定,但煤油需求占总需求比例有一定上升,而柴油和汽油比例有一定的波动;需求柴汽比有一定的升降;用油车辆的数量不断上升,但其增长速度都呈下降的趋势;三类成品油国内价格均低于国际价格,汽油和煤油价格上升较快,柴油价格上升较慢.

Dynamic simulation system of Chinese oil products demand and its simulation

Through the analysis of Chinese oil product demand and supply and with the dynamic theory, the dynamic simulation system of Chinese oil product demand was set up.This system was divided into three subsystems,that is,the gasoline demand sub-system,the kerosene demand sub-system and the diesel oil demand sub-system.On the hypothesis of the high crude oil price,the fast development of economy and the invariable fuel efficiency of oil consuming vehicles,the simulation results showed that the supply and demand o...
