改进社会化互动的疏散系统Cell-DEVS建模与仿真

Cell-DEVS Social Interaction Modeling and Simulation for Emergency Evacuation Systems

针对应急疏散行为受社会化属性驱动而表现出不确定性、互动关系复杂等特征,基于Cell-DEVS语言构建人员疏散系统仿真模型,模型在强化描述行人运动能力的基础上,引入环境熟悉程度、个体视野、沟通与引导及速率区块等社会化互动因素,旨在优化模型算法,完善个体与环境,个体之间互动关系的描述。RESTful web service远程仿真结果进一步证实了社会化互动的存在,提升了模型对疏散系统的描述能力,仿真结果更为可信。进一步显示了模型驱动理论与计算机仿真技术在建筑设计、应急方案制定、公共安全与危机管理等领域的先进性与可行性。

This paper aims to present a Cell-DEVS model for emergency evacuation systems, which behave uncertainty and are intricately driven by the social factors. The model introduces social interaction factors such as familiarity degrees, individual vision, communication and conduction, and velocity zones as the state variables, describing the relationship between the evacuees and environment, as well as the interactions with each other. The algorithm optimization enhances reality of simulation. The RESTful CD＋＋ is applied as middleware to execute remote simulation. The results confirm the existence of social interaction. This work benefits to the architecture design, evacuation planning and public safety management.
