车辆动态竞争系统的动力学分析

Dynamic Analysis of Vehicle Dynamic Competition System

基于利用生态学理论研究企业竞争的模型和方法,本文通过改进LV模型,研究区域物流运输系统中的车辆竞争问题。首先,我们以两家实力相当的运输车队为研究对象,建立了车辆动态竞争模型。其次,根据对平衡点的类型分析,得出两家车队的数量变化规律。由于竞争系统的扰动,我们得到了一个稳定的极限环,并对极限环的产生做出了合理解释。本文利用数值模拟对模型进行检验,保证了模型的合理性。最后,结合社会经济发展规律,对区域物流中运输车队的发展做出相关判断和预测。

Based on the models and methods of applying ecology theory to the study of enterprise competition,this paper improves the LV model in order to solve vehicle competition problem in the research of regional logistics transportation system.At first,taking two teams as the research objects,the vehicle dynamic competition model is established.Secondly,according to the analysis of the type of equilibrium point,the number of the two teams is concluded.As a result of the disturbance of competition system,we get a stable limited cycle,and make a reasonable explanation about the limited cycle.In this paper,numerical simulation was carried out on the model test to ensure the rationality of the model.In the end,combined with the law of social and economic development,this paper makes relevant judgment and prediction on the development of transport fleet in regional logistics.
