摘要
综合运输网络是一个存在多种不确定因素的复杂交通系统,导致了其总体容量的不规律变化.为此建立了考虑不确定因素的综合运输网络流量分配模型,采用网络变换方法描述存在多种运输方式的综合运输系统.并提出了综合运输网络流量分配算法,进而计算综合运输网络的总体容量.结合蒙特卡洛实验,假定各运输弧段的运输能力随机变化,应用网络容量可靠性分析框架,对综合运输网络的容量可靠性问题开展分析试验.结合具体算例,演示了上述分析模型与方法的实现过程及有效性,为系统性地评价综合运输网络的容量可靠性提供了有力的工具.
The comprehensive transportation network was a complicated transport system,and its capacity was usually changing irregularly. To deal with this problem,an assignment model for comprehensive transportation network was built to compute the network capacity of the comprehensive transportation system. The comprehensive transportation system with multi-mode was described by the transformed network representation. Using the Monte-Carlo method,in which the capacity at each individual link was assumed to be changed randomly,the capacity reliability of the comprehensive transportation network was analyzed with numerical experiments.In the example,the effectiveness of the proposed model and solution method was demonstrated. Therefore,the proposed approach provides an efficient tool for evaluating the system reliability of the comprehensive transportation networks.
