| 摘 要： | 为在火灾发生时给逃生人群规划最优的安全疏散方案，基于CCRP算法开发1种火灾情况下受容量限制的动态疏散算法。该算法模型将发生火灾的建筑布局信息表达成节点连接弧形式，鉴于可预测危害蔓延对火灾逃生过程中疏散通道封锁时间的影响，为建筑网络图上的节点赋予“危险时刻”属性，逃生人员通过节点的时刻必须小于该节点的“危险时刻”才能规避火灾危险；基于eclipse软件平台，通过动态疏散算法与相似Dinesh算法应用实例对比仿真分析，验证基于CCRP的动态疏散算法的可行性与优越性。结果表明:通过该算法计算出的逃生路径保证逃生人员在最短时间疏散出去；且其具有安全性高和耗时少等优点。

| Abstract: | In order to plan the optimum safe evacuation scheme for the escape crowd in case of fire,a dynamic evacuation algorithm constrained by capacity in the fire situation was developed based on the capacity constrained route planning (CCRP) algorithm.The algorithm model expressed the layout information of the building where the fire occurred in the form of nodes connecting arcs.In view of the influence of predictable danger spread on the evacuation passage blocking time during the fire escape process,the nodes on the building network diagram was given the attribute of “dangerous moment”,and the moment of escape personnel passing the node must be less than the “dangerous moment” of the node to avoid the fire hazard.On the basis of eclipse software platform,the feasibility and superiority dynamic evacuation algorithm based on CCRP are verified by comparing simulation analysis with similar application examples of Denish algorithm.It showed that the escape path calculated by this algorithm could ensure escape personnel to evacuate in the shortest time,and the escape path planned by the algorithm had the advantages of safety and less time consuming. |
