Simulation Research on Improving the Flow Capability of Emergency Networks

The flow is easily blocked at some nodes in the emergency network.The saturated flow is diversified and stochastic.It is one of the important indices for studying the flow capability of the network under the stochastic flow.To improve the flow capability of the network and reduce the occurrence of blockage,two reconstructed methods are proposed in this paper.The probability distributions of the different saturated flows are obtained by the simulation model.The processing of the two reconstructed methods is analyzed using the two evaluating indicators,i.e.the expected flow of network and the bias-variance of saturated flow.Accordingly,the optimal reconstructing process is proposed.The applied foreground of the two scenarios are analyzed in the end.
