Software reliability growth models based on non-homogeneous Poisson process

Abstract：Non-homogeneous Poisson process is a vital technology of evaluating software reliability, Original failures number and failure-detected ratio are two major parameters to affect software reliability.The paper first defines the software failure distributed, and then presents non-homogeneous Poisson process model.The parameters of models are discussed and analyzed.The restrict condition, parameters, original failures number and failure-detected ratio of models are extrapolated.The assessment methodology about key parameters is given.
