摘　　要：为研究紧急事件下邮轮功能区布局对疏散能力的影响,以降低疏散时间为目标,将改进社会力模型与疏散特征约束结合分析邮轮功能区布局对疏散能力影响模型。改进社会力模型考虑了邮轮内不同功能区乘员疏散时产生的影响力,利用影响力参数修正基础模型中的自驱力并进行仿真验证。在改进社会力模型的基础上,依托总疏散时间建立目标函数,疏散特征约束包括疏散响应时间、疏散速度等,并进一步考虑疏散网络拓扑对乘员疏散性能的约束,旨在根据功能区乘员的疏散特征,基于既有的空间布局,合理调整功能区在现有空间中的分配方式,更好地适应邮轮内的空间约束。以“海洋量子”号邮轮为例,利用Anylogic仿真软件建立第4层甲板经典布局和优化布局模型,通过设定相应的数据参数进行仿真试验,验证了改进社会力模型的疏散效果并得到了一组最优布局方案。仿真结果表明:在前述案例中,优化后的布局方案可将疏散效率提高9.22%。In order to study the effect of cruise functional zone layout on evacuation capability in emergency situation, the impact model of cruise functional zone layout is developed by combining the improved social force model with the evacuating feature constraint. The improved social force model takes into account the motion features of occupants in different functional zones in the cruise ship during the evacuating process, and the influence parameters are used to modify the self-driving force in the basic model and perform simulation verification. Based on the improved social force model, the objective function is established according to the total evacuation time. The evacuation characteristic constraints include the response time, the speed, etc., and the evacuation of the passengers is further restricted by the on-board passage network topology. The research work aims to fully exploit the evacuating characteristics of passenger in different functional zones with consideration of the existing spacial layout. By calculating the optimized allocation based on the spacial setups, the scheme tries to produce better adaptation to the spacial restrictions. Anylogic simulation software is utilized to setup the classic layout model and the optimized layout model. The fourth deck of the "Quantum Ocean" cruise ship is used as the case for study. The simulation experiments are conducted by setting the corresponding data parameters, which can verify the evacuation effect of the improved social force model and yield a set of feasible optimal layout schemes. The results show that in the case of the above configuration, the proposed scheme can improve the evacuation efficiency by 9.22%.
