基于层次式架构的信息系统健康度模型及优化方法

Hierarchy based assessment health model of information system and optimization method

综合考虑物理设施和业务逻辑,基于层次分析法首先提出信息系统运行方式的三层健康度模型,并设计了实时健康度评估算法;然后提出基于健康度优先级的系统局部调整策略,以保障业务系统的稳定运行.实验结果表明,该评估模型能够准确刻画信息系统的健康度,局部调整算法可在不增加物理资源下有效提升系统健康度,且当物理设施发生故障时,系统能通过局部调整策略恢复健康运行.

To evaluate the operation mode of information system,this paper synthetically considers physical facilities and business logic,constructs a comprehensive health model of information system operation mode by using the basic principle of AHP,and proposes a local adjustment strategy based on health priority.The experimental results show that the model can evaluate the health of information system effectively and accurately.The adjustment algorithm proposed in this paper can effectively improve the health of the system operation mode without more resources.Moreover,it can recover effectively when the physical facilities fail.
