基于DEVS／CD＋＋的抢险救灾物资保障仿真建模研究

Research into simulation and modeling of material supply in emergent disaster based on DEVS/CD++

突发自然灾害条件下的抢险救灾行动是典型的离散事件系统,在分析离散事件系统规范(DEVS)模型描述的基础上,构建了抢险救灾物资保障DEVS仿真模型,分析了仿真实体,设计了仿真流程,给出了耦合模型和主要原子模型结构。并在CD++中对该模型进行了仿真试验,得到了较为合理的仿真结果,为开展抢险救灾应急保障模拟训练奠定了基础。

Dealing with emergent disaster is a typical discrete event system. Based on the analyses of Discrete Event System Specification （DEVS） formalism, the DEVS simulation model of material supply in the emergent disaster was made. The simulation entities were analyzed. The simulation flow was designed. The structures of coupled model and main atomic models were given. And the simulation test of this model was completed in CD ＋ ＋. The reasonable simulation results were obtained. It laid the foundation for the development of simulation training on the services of emergent disaster.
