摘要
针对林火行为具有突发性强、处置救助比较困难、破坏性大等特点,将动态数据系统和离散事件系统规范模型相结合,提出了一种基于DEVS建模的动态数据驱动林火蔓延模型。动态数据系统需要通过计算机软件及各环境下数据特点进行交互来实现,特点是数据灵活真实。DEVS支持面向对象建模,可以使系统的建模与仿真趋于模块化、层次化和形式化。该模型是根据动态数据系统和离散事件系统规范模型在林火蔓延模拟应用中各自的结构特点,并结合系统试验区用户的具体功能需求而构建的。将该模型应用于某山场发生的一起森林火灾模拟过程中,具有高度的真实相似性。
According to the characteristics of fire behavior with strong sudden, disposal of difficult rescue, and heavy destructiveness, combining dynamic data system and discrete event system specification model, a dynamic data drivenforestfire spread model is put forward based on devs modeling. The dynamic data system needs to be realized through the interaction between the computer software and the data characteristics of each environment, which is characterized by flexible data and real data. DEVS supports object-oriented modeling, and can make the modeling and simulation of the system modular, hierarchical and formal. The model is set up according to the dynamic data system and discrete event system specification model in forest fire spread simulation application in their structural characteristics, and combined with the specific functional requirements of users of the test region system construction. The model is applied to a mountain field with forest fire simulation process, the model to simulate is close to actual situation, with the height of the true similarity.
