摘要
基于结构熵理论,从物流的角度建立的交通运输网时效和质量定量计算模型,可用于对中国、美国的交通运输网的结构有序度进行比较研究,由此所得的结果表明,中国的交通运输网结构有序度在时效方面低于美国,但在质量熵方面高于美国。这一研究结果可为中国的交通运输网建设提供一个定量辅助分析工具。
Based on the theories of structure entropy, the time-effect and quality quantitative mathematical model of transport network is established from the standpoint of logistics. The comparative aplication research of the model to evaluate the order degree of transport network between China and USA shows that the order degree of transport network of China was lower than that of USA in time-effect,higher in massic entropy. This study can be one of quantitative and analytical methods for transport network reform of China.
