【摘要】 为克服基于最短距离方法构建的地面场在指引元胞移动时由于路径上存在障碍物而不可行的弊端,提出了一种用元胞格点到出口的最短路径构建地面场的新方法。在此基础上,以多障碍情景下的矿工疏散问题为例,假设矿工以无后退移动方式疏散,建立了矿工紧急疏散模型,并用Matlab进行了仿真模拟。结果表明,构建的模型能够真实地模拟矿工的疏散行为,平均疏散时间随位置保持概率增大而迅速增大的模拟结果与实际情况相符。更多还原

【Abstract】 In the case that there are obstacles in the path guiding by floor field,which is designed based on the shortest distance method,the moving-cellular way is impracticable. To overcome the drawback,a new method to establish floor field is put forward by employing the shortest path from lattice point to exit.On this basis,taking the miners’ evacuation problem as an example and supposing the miners evacuate without backward move,an urgent evacuation model for miners is designed and some simulations carried out with Matlab. The results show that the established model can simulate the evacuation of miners. The average evacuation time rapidly increases along with the increase of position-keeping probability,which is consistent with the actual situation.更多还原
