一种改进的基于架构的软件可靠性模型
Improved architecture-based software reliability model
摘要
Abstract
Architecture-based software reliability analysis typically takes the reliability of component as an invariable property of component itself, while disregards the fact that it is changed when the component context that it interacts with is changed due to a different operational profile of the system.This paper aims at architecture-based software reliability model which is one type of approach modeling component-based software,introduces an input profile matrix of transition destination component to build a re-lationship between operational profile and the component reliability,and provides an improved composite algorithm to solve the model.The application analysis of a case study indicates that this model is able to fully capture the impact of different opera-tional profiles on the system reliability in aspects of both model parameters,transition probability and component reliability.This ability will benefit reliability analysis of higher accuracy at the stage of system design.关键词
