群体组织模型是深入研究群体协同行为的基础,而现有的组织模型大多集中在对Agent组织的结构或个体低层指令级的交互上,不能描述组织高层的动态任务交互.提出一个新的群体组织协同关系模型GRNA.该模型包含两个子模型:认知模型和交互模型.认知模型构建于领域本体之上,为GRNA模型提供准确的术语定义；交互模型则基于描述任务逻辑理论,反映了群体的任务协同语义.实例分析表明,GRNA支持对群体规范和能力的描述,提供了组织任务可完成性的可判定的推理服务,能够描述组织的高层任务交互语义.%Modeling group organizations is the foundation for further research on group coordinative behavior. Most of existing organization models consider Agent organization or individual low-level instruction interaction, but concern little about the description of high-level dynamic task interactions. In the paper, we propose a novel group organizational coordinative relationship model named GRNA (Group-Role-Norm-Ability) to describe the organizational coordinative relationship of agent groups. The GRNA model is based on the description logic of the task and it contains two sub-models: cognition submodel and interaction sub-model. The cognition sub-model which provides accurate definitions of terms is built on domain ontology, while the interaction sub-model based on the description logic of tasks reflects the collaboration between the tasks. Through the case study, we show that the GRNA model can describe norms and abilities of groups, provide powerful services of decidable deduction for the achiev-ability of organization tasks, and express high-level task interaction semantics of groups.
