航天装备仿真资源库系统代理通信机制设计

Design and Implementation of Agent-based Space Equipments Simulation Resources Repository System's Agent Communication Mechanism

航天装备仿真资源管理系统的资源管理不仅需要通过代理管理相应的模块,更重要的是利用代理之间的交互实现资源的高效传输和管理。实现代理之间交互的关键是选择合适的代理通信机制。由于航天装备仿真资源分布性、多样性和可重用性的特点,代理间采用了基于消息的通信机制,并依据KQML语言的规范定义了消息通信的信息流和控制流。基于消息的代理通信机制不受简单命令和响应结构的限制,克服了黑板系统的缺陷,充分体现基于代理的方式构建系统的特点,很好地解决了信息资源和操作对象的分布性以及复杂性问题。

Resource management of the Space Equipments Simulation Resource Management System needs the agents to manage the relevant modules,the more important mission is to use the interaction among the agents for implementing the highly efficient transmission and management.The key of implementation of the interaction among the agents is to choose an appropriate agent communication mechanism.Because the characters of Space Equipments Simulation Resource are distributed,diversified and reusable,the message based communication mechanism among the agents is adopted,and the message communication information flow and control flow based on the criterion of the KQML are defined.Message based agent communication mechanism is not limited by the simple order and response structure,conquers the limitation of the blackboard system,and fully incarnates the character of the agent-based manner of constructing the system,primely resolves the distribution and the complexity of the information resource and operation object.
