A Software Reliability Model with Exponential Repair Time

Conventional software reliability models assume that the time to remove a fault is negligible. This rigid assumption limits the models' prediction precision and their application. Based on JM model, we propose a software reliability prediction model involving fault-remove time which followed exponential distribution. We provide the maximum likelihood parameter estimation equations of this model. We also provide several reliability prediction equations by using markov process. Illustrations of the proposed model by using real data are provided.
