Abstract

Software maintenance is a process of modifying existing operational software while leaving its primary functions intact. Easily maintainable software saves large costs in industries. Software maintainability assessment is a major issue these days. In order to assess maintainability we consider four major aspects of software i.e., average numbers of live variables, average life span of variables, average cyclomatic complexity and the comment ratio. This paper proposes a fuzzy logic based precise and easy approach to quantify maintainability of software.
