Industrial application of clone change management system

Clone change management is one of crucial issues in open source software(OSS) development as well as in industrial software development (e.g., development of social infrastructure, financial system, and medical equipment). When an industrial developer fixes a defect, he/she has to find the code clones corresponding to the code fragment including it. So far, several studies performed on the analysis of clone evolution in OSS. However, to our knowledge, a few researches have been reported on an application of a clone change management system to industrial development process. In this paper, we propose a clone change management system based on the categorization of clone evolution, and then present case study of industrial application. In case study, we confirmed that the proposed system suggested two unintentionally developed clones in a half of the month.
