Approach to Predict the Software Reliability with Different Methods Ossmane Krini and Josef Börcsök Computer Architecture and System Programming, University of Kassel Wilhelmshöher Allee 71, 34121, Kassel, Germany o.krini@uni-kassel.de, j.boercsoe@uni-kassel.de Abstract This particular essay expounds upon how one can foresee and predict software reliability. There are two major components that exist within a computer system: hardware and software. The reliabilities between the two are comparable because both are stochastic processes, which can be described by probability distributions. With this said, software reliability is the probability that will function without failure in a given software and in a given environment during a specified period of time. Thus, this is why software reliability is a major and key factor in software developmental processes and quality. However, one can spot the difference between software reliability and hardware reliability where it concerns the quality duration and the fact that software reliability does not decrease its reliability over time.
