Abstract

Component-Based Software Engineering is a perfect approach for rapid software development with the maturity of components. The estimation of Component-Based Software (CBS) reliability from the reliabilities of constituent components and architecture is a matter of concern. In this paper we propose a Reliability Estimation Model for CBS to estimate the reliability through path propagation probability and component impact factor. This model incorporates the idea of path propagation to estimate overall system reliability after integration of components, which considers the contribution of the individual components that get activated during an execution path. This model also estimates the impact factor of individual components on overall reliability. The impact factor can be used to focus the efforts to obtain the best reliability improvements. To evaluate the Reliability Estimation Model including both the factors, we implement it through JAVA, which is based on an adapted example case study. Lastly we conclude that proposed model is useful to estimate the reliability of CBS and can be used adaptively in early stages of software development.

基于构件的软件可靠性评估新模型

随着组件的成熟，基于组件的软件工程是实现快速软件开发的理想方法。从组成组件和体系结构的可靠性来评估基于组件的软件(CBS)可靠性是一个值得关注的问题。本文提出了一种基于路径传播概率和组件影响因子的CBS可靠性估计模型。该模型结合了路径传播的思想来估计组件集成后的整体系统可靠性，它考虑了在执行路径期间被激活的单个组件的贡献。该模型还估计了单个部件对整体可靠性的影响因子。影响因子可以用来集中精力，以获得最佳的可靠性改进。为了评估包括这两个因素的可靠性估计模型，我们基于一个改编的示例案例研究，通过JAVA实现了它。最后，我们得出结论，该模型可用于估计CBS的可靠性，并可在软件开发的早期阶段自适应使用。
