Abstract:
Many reliability growth models related to the concept of multi upgradation
have recently been proposed. This concept has helped software
developers to develop a competitive edge over competitors by regularly
introducing their software upgrades in the market at the optimal moment. The
software reliability literature offers many different release-time policies, both
under crisp and fuzzy environment. This paper presents a generic model of a
multi-upgraded software system. The optimal scheduling policy for software
under a fuzzy environment was determined. The proposed model was examined
on a real-life failure data set of four software releases. The results obtained are
encouraging.
