基于目标最优化的大件运输路径选择研穷

为了提高大件运输的安全性和效率，通过大量的实际调查，以大件运输的供需出发，结合交通工程学的知识和大件运输的特点，从可行、经济、时效、扩展四方面进行综合分析确定大件运输选线的原则，并应用目标最优化理论，优选出东西、南北方向的公路运输线路线．

Selection Based on Objective Optimization of Large Transport Path

With the development of China＇s economy and the acceleration of global economic integra-tion, more and more large-scale petrochemical, power, Heavy project began construction in the coun-try, making the domestic international exceed the standard dimensions and weight of large equipment transport devices become increasingly frequent. In order to improve the safety and efficiency of large transport, through a lot of investigation, based on the supply and demand of large transport, combi-ning of traffic engineering knowledge and the characteristics of the large transport, considering of the feasible and economically viable, timeliness, extended four aspects of a comprehensive analysis are choosen to determine the principles of the large transport line selection. Objective optimization theory is applyed to preferably the east-west and the north-south highway transport route, which provides a theoretical basis to build a large transport intermodal network in the country.
