Abstract | The software systems used in the field environments are the same as or close to those used in the development-testing environment; base on this, existing software reliability models are applied to software testing data and then used to make predictions on the software failures and reliability in the field. However, the systems may be used in many different locations. In this paper, we present a new model with consideration for the fault detection rate of the Weibull function in operating environments using the Exponential distribution, and examine the goodness-of-fit of the proposed new model and other models based on two datasets. The results show that the proposed new model fits significantly better than other models.
