Software maintainability is an effective measure for the system quality in the stage of software development. Understandability, modifiability and analyzability are the important factors of the software maintainability that can judge the maintainability of the system. These three factors depend mainly on the 3 size and 8 structural metrics of various UML specifications. The authors proposed the different models to measure the maintainability and its important three factors in this paper. In the process of developing the models they used exponential non-linear representation.
