Abstract:

Architecture-based software reliability models are established during the early phase of software development. The models can perform a prior analysis of software reliability. It is a basic factor for software architecturechange, edition update and upgrade. However, the early architecture-based models are most applied to homogeneous software architectures, which could not satisfy the requirement of multiple architecture software. Multiple architecture styles are firstly analyzed. Then, a heterogeneous architecturebased software reliability model is proposed. Finally, an available example is presented with the model according to the estimation steps.
