摘要: 针对化工园区突发事件中人员疏散问题,基于网络流控制理论,借助时间窗的概念研究了人员疏散过程中路径冲突和通道受阻问题,在Dijkstra算法基础上建立了多源点人员疏散最短路径模型,提出了模型算法和步骤,结合某化工园区的实例进行验证,结果表明:该疏散模型及算法可行,能有效地缩短人员疏散所需时间。

Abstract: Aiming at the problem of evacuation in chemical parks under emergency, this study is based on the network flow control theory. The concept of time window is used to conduct the problem of path conflict and channel obstruction in the process of evacuation, and the multiple sources model is established on the basis of Dijkstra algorithm. Focus on the algorithm and steps of the shortest path model for human evacuation. In addition, the model is verified with the example in a chemical park. The results indicate that the evacuation model and algorithm are feasible and effective, and can reliably shorten the time required for evacuation.
