基于多代理协作的IT 复杂应用管理模型,给出了用于IT 复杂应用管理的代理能力模型及管理任务分解问题的基本原则,进而提出了一种动态多角色的管理任务层级分解算法.算法考虑到多代理的能力限制,以及由管理端策略、IT 基础设施或业务逻辑改变而引起的IT 复杂应用管理任务的动态性.同时,算法兼顾了分解后子任务的平衡性,即执行子任务的多代理的负载平衡性,能够有效地提高多代理的执行效率和稳定性.仿真结果显示,由该算法所分解的子任务集呈现出了良好的执行效率及稳定的负载平衡性.

[Abstract]
This paper presents a dynamic hieratical task decomposition algorithm which applies for a management module of complex IT application based on multi-agent collaboration. The algorithm considers the capacity restriction of multi-agent and the dynamicity of management task caused by the variation of management strategy, IT infrastructure and service logic. Meanwhile, it also considers the balance issue of sub tasks after decomposition, which is the load balance issue of the corresponding multi-agent. The algorithm effectively improves the task executing efficiency and stability of multi-agent. Simulation and analysis results show that the algorithm in this paper is more efficient and has steadier load distribution than that of other compared algorithms.
