In this article, first, we introduce the concepts of Grid and Agent Grid based on our own understanding. Then we compare Agent Grid with the traditional Multi-Agent System to make the concept and characters of Agent Grid much clearer. Next, the key techniques of Agent Grid, such as Agent Grid System Architecture, System Models, Intelligent Agents and Agent-Based System Resource Management, are thoroughly illustrated. Finally, we briefly discusse the future applications of Agent Grid.展开更多
