| 摘 要： | 基于流动单元在网络中随机流动的特点,提出一种新的网络模型——随机流动网络;建立了该网络模型中个体流动单元随机流动的饱和流模型。网络有多种饱和状态并且总有相对应的堵塞割集。尝试用两端点网络饱和流值不小于给定需求的概率评估网络实际流通能力的可靠性。基于饱和流模型,可以仿真出网络中饱和流分布及各弧流量分布情况;利用网络中堵塞割集弧流量分布建立了评估网络可靠性的表达式。最后通过实例分析给定不同网络需求时相对应的可靠性。

| Abstract: | Based on the phenomenon that moving objects move stochastically in transport networks,a new network model,stochastic moving network(SMN),is proposed.The saturated flow model of SMNs is set up.The saturated flows of SMNs have multiple values and there exists corresponding blocking cutset.The probability that the saturated flow of the network is not less than d is used to evaluate the flow capability of the network.Based on the new model,the flow probability distribution in every arc is obtained by simulation.An algorithm based on the blocking cutset of the SMN is proposed to evaluate network reliability.An example is used to show how to calculate the corresponding reliabilities in the different given demand of the SMN. |
