N2 - In this paper, we develop a new software reliability model incorporating the uncertainty of system faultdetection rate per unit of time subject to the operating environments. Examples are included to illustrate the goodness-of-fit of proposed model and several existing NHPP models based on a set of failure data collected from software applications. The results show that the proposed model fit significantly better than other existing NHPP models based on MSE value. We also present a new method called, normalized criteria distance (NCD), for selecting the best model from among SRGMs based on a set of criteria taken all together. Example results show the proposed method offers a promising technique for selecting the best model based on a set of contributing criteria.
