A Development of Clone Change Management System and Its Application to Actual Project

Code clone is one of the major problems for software maintenance. A code clone is a code fragment that has identical or similar portion in source code. In order to manage code clones, software developers should consider consistent modification of clone sets (i.e., a set of code clones identical or similar to each other) and merging clone set into a single function. In this study, we developed a code clone change management system for clone maintenance. Moreover, we confirmed the usefulness of the developed system by applying to industrial software development.
