摘    要:针对缺乏以数据为基础的分析模型和信息以非结构化形式存储的复杂IT系统中的软件自修复问题,提出了一个基于过程模型的功能点切片模型(FPSM).该模型在功能点分析5类组件的基础上,建立组件间的各种依赖关系,形成系统功能点依赖图,再应用功能点切片的方法,实现组件间的自动化关联分析,以支持软件系统运行阶段功能异常的自修复.模型实现了异常原因定位、变更影响分析以及解决方案匹配的自动化.实验结果表明,功能点切片模型和基于模型的切片器工具由于对系统组件进行了有效的定义和关联,能有效地降低异常事务的风险指标,并能够减小系统故障的发生频率.

关 键 词:功能点切片模型  软件自修复  自治计算

Abstract:A function point slicing model (FPSM) based on the process model was proposed to solve the software self healing problem in the IT systems that lack data based analysis models and whose information is stored in non structural way. The model based on the five function components built different relationships within the components and the function point dependency graph, and then applied function point slicing to undertake the autonomic relation analysis in order to support self healing during the exception time of software running. The model realized the automation of exception cause determining, effect analysis of changes and solution matching. The experimental results indicate that the application of FPSM and FPS Tool can reduce risk indicators and frequencies of exceptions.
Keywords:function point slicing model (FPSM)  software self-healing  autonomic computing
