On the modelling and testing of recovery block structures

The authors proposes a reliability model for recovery block structures based on error events that can be observed and distinguished during testing. Strategies are described for the collection of failure histories, which are needed to estimate the model parameters and obtain dependability predictions. Given that the software goes through different testing stages, the model can be employed at different points of the development cycle to assess or forecast the quality of project choices and the resulting product.<<ETX>>
