摘　　要：针对目前定量观测、分析和控制Swarm突现行为研究中的困难，在定性分析突现行为的基础上，提出了多个可定量度量Swarm突现行为的指标，给出了各指标的依据和计算方式．Swarm模型仿真验证了各指标的有效性，分析了其彼此之间的相关性，发现了各指标的变迁区域可反映Swarm行为的突现阶段，同时，各指标的变化从不同层面反映Swarm中内在个体行为交互和局部环境变化情况，而且，彼此之间的相互关联性可有效展现整体行为的稳定程度．To deal with the difficulties in quantitatively observing, analyzing and control the Swarm emergent behaviors, we, on the basis of qualitative analysis on the emergent characteristics, propose several metrics for describing the Swarm emergent behavior along with their implications and computation. The validity of these metrics is proved by the simulation of a specific Swarm model; and the relations between them are analyzed. From the quantitative analysis, it is found that the transition region of each metric reflects the emergent phase of the Swarm behavior. Meanwhile, the change of the metric reflects the interaction between individual intrinsic behavior and the alteration of local environment in different levels. Furthermore, the correlation between metrics shows the stability of the Swarm behavior effectively.
