软件设计阶段基于UML的SFMEA方法研究

软件失效模式与影响分析(SFMEA)是提高软件可靠性与安全性的重要手段之一,近年来在很多领域得到了越来越多的应用。当前,面向对象方法已成为国内外软件设计的主流,UML亦已成为软件界统一的建模语言。因此,基于UML的SFMEA分析方法对面向对象软件来说具有重要意义。本文对基于UML建模软件的SFMEA方法进行研究,分析在软件开发过程的早期——设计阶段使用UML建模元素的特点,建立了顺序图和类图与SFMEA分析要素之间的关系,提出了一套分析方法,并进行了实例验证。

The research on the method of SFMEA UML-based in the software design phase

As the one of the most important methods used to improve the software reliability and safety,Software Failure Mode and Effect Analysis(SFMEA) has increasingly been applied to many areas.Meanwhile,the Object-Oriented method has currently been the main technique for software design at home and abroad,also the same as UML——Unified Modeling Language.Therefore,that the method of SFMEA based UML is important to Object-Oriented software.In this paper,the resaearch on the method of SFMEA based UML takes advantage of the characteristics of the UML elements in the early software development process such as design phase,builds up the relationships respectively between Sequence diagrams and SFMEA,also between Class diagrams and SFMEA,brings forward a set of method,and lastly is validated in a software case.
