能力是规范和描述Ａｇｅｎｔ、研究和分析Ａｇｅｎｔ计算以及设计Ａｇｅｎｔ的一个重要抽象概念．文中基于一种主观的观点提出了Ａｇｅｎｔ计算的能力理论以支持Ａｇｅｎｔ计算的理论研究，提出了规划树概念以刻画Ａｇｅｎｔ如何在动态、不确定的多Ａｇｅｎｔ系统中通过对其规划进行合理、有效的组织来实现其任务．基于多Ａｇｅｎｔ系统计算的逻辑框架，文中给出了能力概念的形式化语义定义，获取和描述了它的一些重要属性 Ability is to standardize and describe Agent, research and analysis of Agent computing and design an important abstract concept of Agent. Based on a subjective point of view, this paper proposes the theory of agent computing capabilities to support the theoretical study of Agent computing. The concept of the planning tree is proposed to describe how Agent can make reasonable and effective planning in a dynamic and uncertain multi-agent system Organize to fulfill its mission. Based on the logical framework of multi-agent system computing, a formal semantic definition of capability concept is given, some important attributes of it are obtained and described
