摘　　要：为了解决大规模、多层次复杂空间系统以及多结构类型的网络系统元胞自动机模拟问题,提出了多区域耦合元胞自动机从众模型建模方法。首先根据区块特色将大规模区域划分成若干个相互邻结的子区域,利用空间网格化方法提取子区域元胞的区域属性,经过网格的重定位提取耦合边界上元胞的区域属性。然后,针对不同子区域建立不同的元胞自动机从众模型,并确定子区域间能反映从众行为和辐射影响的信息交换方法。此模型准确地描述了大规模复杂系统具有从众行为、自组织要求和辐射影响的系统演化模拟问题,具有很好的应用价值。To simulate large-scale or hierarchy complicated regions or multiple strucaxres network system by use of cellular automata model, a modeling method of multiple regions coupled herd cellular automata model was put forward. In the model, a larger-scale region was divided into many sub-region blocks according to the characteristics of theses blocks, the region attributes of cells in these sub-regions were extracted with the space gridding method, the region attributes of cells in the coupled borders were extracted with the by grids relocating. Then the different CA models were established aiming at different sub-regions, and information exchanging method between sub-regions which couM describe herd behaviors, self-organizations and irradiation effects was defined. The model describes correctly the evolution simulation with herd behaviors, self-organizations and irradiation effects of large-scale complicated system, and it has good application value.
