异构软件体系结构的可靠性模型
Heterogeneous architecture-based software reliability model
摘要
Abstract
The application of existing architecture-based software reliability models is strictly limited to software component tran-sitions satisfying Markov properties.When software has heterogeneous architecture which contains both deterministic and probabilis-tic transitions, these models intentionally model it as a Markov process.The loss of accuracy of reliability estimation comes as a result.In order to resolve heterogeneous software architectures,a new reliability model is presented based on analysis of component transitions.An algorithm generating Markov chain from heterogeneous software architecture modeled in UML sequence diagram is proposod.A case study shows the new model can yield more accurate reliability estimation result than existing models.关键词
