摘要
扩展影响图是决策者基于不确定信息表示来求解复杂决策问题的图模型,由影响图延伸而来。体系结构可靠性分析是度量体系结构质量的重要内容之一。介绍了扩展影响图的基本思想,引入了防御图原理来构建体系结构可靠性的扩展影响图,通过与数据模型结合,给出了评价目标节点的效用值的方法。实验结果验证了基于扩展影响图的体系结构可靠性分析的可行性。
Extended influence diagram is a graph model to solve complex decision problems based on uncertain information indicates,which extends from influence diagram.Architecture reliability analysis is one of the main contents for the quality measurement of architecture.This paper introduced the basic idea of extended influence diagram,developed extended influence diagram of architecture reliability with the defense graph,then combining with architecture data model,evaluated the utility value of the target node finally.The experimental result suggests the feasibility of architecture reliability analysis with extended influence diagrarn.
