本文以此为背景,提出了基于事件驱动的BDI agent实现体系结构,用信念(Belief)、事件(Event)、规划(Plan)等内部特征来描述软件agent,并给出了面向对象层次上的软件agent的UML模型,该模型定义了构成软件agent的四个对象:Agent、BeliefSet、Event、Plan 为描述这些对象及其交互关系,本文以java语言为基础,扩展出了能描述这四个对象的java类以及描述其交互关系-this background paper, based on Event-Driven Implementation BDI agent architecture, with conviction (Belief), event (Event) plan (Plan) to describe the characteristics of the internal software agent, and given the level of object-oriented software agent UML model, The model defines a software agent constitute the four targets : Agent, BeliefSet. Event, Plan to describe these objects and their mutual relationship, this paper-based java language, can be expanded with a descr iption of the four types of java object and describe their mutual relationship
