摘　　要：为训练客船驾驶员应急疏散组织能力,优化客船疏散方案,依托航海虚拟仿真训练平台,基于改进的蚁群算法,提出一种考虑邻接网格面积与转向角度等因素的疏散模型,采用一种改进的约束Delaunay三角网生成算法高效生成导航网格.基于"育鹏"轮建立船舶三维场景,进行人员疏散过程仿真实验.结果表明,该模型有效地优化了多层甲板复杂场景中的人员疏散路径,充分展现了不同年龄、性别疏散个体路径选择的差异性,为具有复杂人群组成结构的客船应急疏散演练提供了一种良好的解决方案.In order to train the emergency evacuation organization ability of passenger ship officers and optimize the evacuation scheme of passenger ship,an evacuation model considering the adjacent mesh area and steering angle was proposed based on the navigation virtual simulation training platform and the improved ant colony algorithm,and an improved constrained Delaunay triangulation algorithm was used to generate navigation mesh efficiently.Based on the ship’s three-dimensional scene of"YuPeng",the simulation experiment of evacuation process was carried out.The results show that the model effectively optimizes the evacuation path in the multi deck complex scene,fully shows the differences of individual evacuation path selection of different ages and genders,and provides a good solution for the passenger ship emergency evacuation drill with complex crowd structure.
