| 摘要: |
| Agent作为一种受限的智能对象,对Agent的继承特性进行深入研究并将继承机制嵌入到AOP(agent-oriented programming)中则具有重要意义.文章基于BDI Agent模型,对软件Agent的继承性和复制行为进行了研究.从单继承和多继承两个方面给出了Agent继承的语义,将Agent实例的动态复制机制形式地划分为功能分割、逻辑分割、择优分割和返祖分割这4类,分析了每类分割方式的作用,并基于电子市场系统应用背景给出了相应的实例. |

| Abstract: |
| Being a kind of restricted intelligent objects, agent is a natural way to research the inheritance feature of software agent and integrate inheritance mechanisms into AOP (agent-oriented programming). Based on BDI model of agents, the semantics of inheritance and cloning behavior of agents are addressed in this paper. The semantics of inheritance are discussed from two aspects: single inheritance and multiple inheritance. For cloning behavior, the authors identify and formally classify the dynamic cloning mechanisms of agent instances into four types: function split, logic split, preference split and retrogress split. The principle of each cloning mechanism is presented and the examples are provided based on the electrical commerce systems. |
