Generally, the human emergency evacuation model can be summarized into two types. The first series of evacuation model refers to the evacuation behavior with predetermined plan and certain route, in which human evacuate in the same and mean evacuation velocity, whose main purpose is to study the crowd evacuation progress. The second series of evacuation model, which is discussed in this paper, studies the stochastic evacuation behav- ior rules and the optimum of the whole evacuation progress. First of all, on the base of the network model of the emergency evacuation space and the optimum theory , we should establish the optimum model of the multi-objective emergency evacuation Furthermore , according to an application study on a residential building , we should realize the timely optimum simulation of the emergency evacu- ation performance. The study achievement can pro- vide valuable references to the performance-based e- vacuation design of building.%首先对应急疏散空间进行网络模化，进而利用网络流原理和最优化理论，建立多目标应急疏散系统，疏散路线全局优化的数学模型，并通过对一民用住宅建筑物应急疏散性能的实例研究，进行关于最优应急疏散路线的动态模拟分析。其研究成果可以为建筑物性能化安全疏散设计提供非常有价值的参考依据。
