Software Maintainability Metrics Based on the Index System and Fuzzy Method

An index system is proposed to solve the problem of software maintainability metrics. On the basis of quantitative procedural information, this paper uses Analytic Hierarchy Process (AHP) to determine the weight of the evaluation indices, uses the fuzzy evaluation method to deal with the quality of the indices, gets the quantitative result of software maintainability evaluation and solves the multi-index evaluation problems effectively. A representative example is applied to prove the index system and the evaluation methods feasibility.
