Description
Summary:This paper proposes a method that aggregates similar portions in a program into one common portion and redesigns current program structure to appropriate program structure. When a new function is added to an existing program, the function tends to be developed by copying & pasting a portion in the program and modifying its portion. As a result, it becomes to exist many similar portions in the program. In the case that error modifications or changes occurs in the similar portion, appropriate modifications are required to the all similar portions. It would be considered that the quality and efficiency of those tasks are decreased. So that, this paper proposes a method that detect similar portions with minor modifications and a method that aggregates those similar portions to one appropriate common portion with well-defined program structure. As a result, current program becomes to be refined to the program that can accommodate future modification or changes properly.
