New scientific contributions to the prediction of the reliability of critical systems which based on imperfect debugging method and the increase of quality of service

This paper presents a new method by which it is possible to realistically predict the software reliability of critical systems. The main feature of this method is that it allows estimating the number of remaining critical faults in the software. The algorithm employs well-known methods such as Imperfect Debugging and it provides a more reliable prognosis than the methods conventionally used for this purpose. Furthermore, the new approach describes two processes of handling critical failures (one for detection and one for correction). The new algorithm also takes into account the socalled repair time, a measurement that is vitally important for a reliable prognosis. For use in the prediction model, it is mathematically described as a time function.
