公路交通运输可持续发展系统的多目标优化决策

Multi-objective optimization decision of sustainable development system in the highway transportation

在对公路交通运输可持续发展系统描述的基础上,建立了公路交通运输可持续发展系统的多目标优化模型.用中国20世纪90年代的统计数据进行实证分析,验证了模型的可行性.在运算中发现投资效果系数逐渐减小,认为是中国公路交通运输系统走向可持续发展之路的动向.

On the basis of describing the sustainable development system of the highway transportation,a multi-objective optimization model of sustainable development system in the highway transportation is set up, and its feasibility is testified by using the statistics of the nineteen nineties in China. In the process of computing,it is found that the investment effect coefficients became smaller by and by. It can be thought to be the result of the gradual optimization of investment structure and the trend of the highway transportation sustainable development in China.
