基于构件软件的可靠性分析技术—FTA

FTA as a Reliability Analysis Technique for Component-Based Software

快速、高效是软件开发追逐的目标,集中体现软件复用思想的基于构件软件技术继面向对象技术后成为现今软件工程实践和研究的热点;软件所扮演的角色日趋关键,高效开发的同时更需要高可靠性的软件。论文所关注的就是针对开发设计阶段的基于构件软件,采用FTA技术,考虑等概率条件下的软件运行剖面,进行面向软件运行的可靠性分析,试图为软件的设计和测试提供更具有实际意义的反馈和指导,进而增强软件的可靠性。文章还介绍了基于这样的技术针对小型的基于构件软件进行的实证分析。

With the need of rapid,effective software develop ment ,component-based software,stepping from the very con-cept of software reuse,is becoming the focus of nowadays engineering practice and science research.At the same time ,the role software plays is becoming more and more important ,so high reliability is essential with the need of effectivity.This paper mainly discusses how to apply FTA technique into the reliability analysis on component-based software.With software operational profile simplified model(with equal probability)considered,the authors are intending to provide more practical feedback to software design and direction to software test.A case study is also presented applying this tech-nique on a small component-based software.
