二维元胞自动机模型常用于林火蔓延中,但其存在迭代次数过多、进化过程不充分以及结束迭代的条件不明确等缺点。针对上述问题,提出一种基于多目标遗传算法的三维元胞空间林火蔓延模型。首先,将影响和决定林火蔓延因子的主体作为元胞引进二维元胞自动机模型中;其次,为了减少二维元胞自动机模型的迭代次数,明确结束迭代的条件,首先对初始化方式改进,采用三维球形元胞空间对二维元胞空间进行改进,其次通过多目标遗传算法对元胞自动机算法进行改进,从而提高林火蔓延模型预测精度。通过仿真结果,对比分析传统的二维元胞自动机模型、王正非模型以及Rothermel模型与本文提出的方法,可知本文提出的方法迭...

Two-dimensional cellular automata model is often applied to simulate the forest fire spreading. However, the model has many disadvantages which include numerous iteration times, unfinished evolutionary process, uncertain condition of iteration, etc. Aiming at tackling these problems, a 3-D cellular space fire spread model based on genetic algorithm with multiple objectives is proposed. First, the main factors that influence the spreading of forest fire are applied to the two-dimensional cellular automaton model. Secondly, to decrease the iterations of cellular automaton model of spreading fore...
