Analysis on some of software reliability models

Software reliability & maintainability evaluation tool (SRMET 3.0) is introducted in detail in this paper, which was developed by Software Evaluation and Test Center of China Aerospace Mechanical Corporation. SRMET 3.0 is supported by seven software reliability models and four software maintainability models, Numerical characteristics for all those models are deeply studied in this paper, and corresponding numerical algorithms for each model are also given in the paper.
