Agent主动目标的形式化模型

在agent结构中,主动目标是一个功能上自含且有自己独立控制流的实体.给出了主动目标相关的语法定义以及主动目标运行的操作语义,而且主动目标驱动下的BDI agent结构也被形式化地定义出来.区别于以往的一些BDI agent结构,目标不是隐含地表示而是作为实体显式地表示在agent结构中,使agent结构很自然地支持并行的目标,这被认为是agent理性行为的一个重要方面.此外,对目标的显式定义也为agent在动态的环境中对承诺的重新考虑带来了方便.

A Formal Model for Agent Active Goals

In agent architecture,an active goal is a functionally self-contained entity with independent control flow.The related syntax of active goal and the operational semantics of active goal execution are presented. Furthermore,the BDI agent architecture driven by active goals is formally specified.Different from some former BDI agent architectures,goals are explicitly represented in the agent architecture as active entities.Parallel goals are supported in the architecture level by a very natural fashion,which is considered to be an important aspect of the rational behavior of agent.What's more,the explicit definition of goals provides convenience to the reconsideration of commitments for agents situated in dynamic environments.
