This paper considers a software reliability model which allows for two types of imperfect debuggings at each failure of the software system. For one type of imperfect debugging, the fault that causes the failure is imperfectly debugged without changing the fault contents of the software system. For the other type of imperfect debugging, the fault is not only imperfectly debugged, but also a new fault is generated and introduced to the system. The probability of perfect debugging assumed to be an increasing function of the number of repairs performed prior to the failure of the system. Based on the software reliability model presented, we develop a profit model, assuming the truncated expected software profit. The optimal values of release time are shown to be finite and unique. Numerical examples are provided for illustrative purposes.
