摘要：Masked data are the system failure data when exact component causing system failure might be unknown.In this paper,the mathematical description of general masked data was presented in software reliability engineering.Furthermore,a general maskedbased additive non-homogeneous Poisson process(NHPP) model was considered to analyze component reliability.However,the problem of masked-based additive model lies in the difficulty of estimating parameters.The maximum likelihood estimation procedure was derived to estimate parameters.Finally,a numerical example was given to illustrate the applicability of proposed model,and the immune particle swarm optimization(IPSO) algorithm was used in maximize log-likelihood function.
Masked data are the system failure data when exact component causing system failure might be unknown. In this paper, the mathematical description of general masked data was presented in software reliability engineering. Furthermore, a general masked- based additive non-homogeneous Poisson process （NHPP） model was considered to analyze component reliability. However, the problem of masked-based additive model lies in the difficulty of estimating parameters. The maximum likelihood estimation procedure was derived to estimate parameters. Finally, a numerical example was given to illustrate the applicability of proposed model, and the immune particle swarm optimization （IPSO） algorithm was used in maximize log-likelihood function.
