Applying excel in the weight calculation of software maintainability evaluation based on AHP

In order to assure the quality of software maintainability evaluation, setting up a reasonable index system and distribute the index weights with reason is the most important thing. In this situation, this paper set up an index system of software maintainability evaluation firstly, based on two principles such as giving prominence to main indexes and that indexes are usually required be measurable. Then, it did calculation upon the index weights with the application of analytic hierarchy process (AHP). Finally, the implementation of AHP in Excel validates fully that AHP is an available and efficient solution to calculate the index weights during software maintainability evaluation. In conclusion, using Excel to calculate the weights of software maintainability evaluation based on AHP is original.
