我们根据在南非德霍普自然保护区收集的数据，提出了一个基于代理的模型，描述了一群查克玛狒狒（Papio hamadryas ursinus）的关键活动。我们根据模型复制观察到的动物活动模式的能力以及控制代理决策过程的参数与模型预测之间的关系来分析模型的预测。在模型开发的当前阶段，我们能够证明，在广泛的决策参数值范围内，狒狒能够满足其精力和社交时间要求。模拟结果还表明，有关运动的决策（群体行动选择）对结果的影响最大。模型的预测与观察到的活动模式不一致的情况突出了现场数据中缺少的关键要素，这些要素需要在后续的现场工作中收集。根据我们的经验，我们相信群体决策是未来研究的沃土，基于主体的建模为理解群体行为选择提供了广阔的空间。
We present an agent- based model of the key activities of a troop of chacma baboons ( Papio hamadryas ursinus) based on the data collected at De Hoop Nature Reserve in South Africa. We analyse the predictions of the model in terms of how well it is able to duplicate the observed activity patterns of the animals and the relationship between the parameters that control the agent's decision procedure and the model's predictions. At the current stage of model development, we are able to show that across a wide range of decision parameter values, the baboons are able to achieve their energetic and social time requirements. The simulation results also show that decisions concerning movement ( group action selection) have the greatest influence on the outcomes. Those cases where the model's predictions fail to agree with the observed activity patterns have highlighted key elements that were missing from the field data, and that would need to be collected in subsequent fieldwork. Based on our experience, we believe group decision making is a fertile field for future research, and agent- based modelling offers considerable scope for understanding group action selection.
