Evaluating the Maintainability of a Software System by using Fuzzy Logic Approach

Maintainability is an important quality attribute for almost every quality model. Maintainability of the software is considered as most expensive phase in software development life cycle as it consumes almost major part of the total effort allocated to the software system. Maintainability evaluation is complex due to its imprecise output. This paper proposes a maintainability model by considering its fuzzy aspects. Since fuzzy modeling deals with uncertainty and impreciseness so this paper uses fuzzy methodology and AHP technique to evaluate the maintainability of the model. Object oriented system has taken as case study for maintainability evaluation purpose.
