Aspect-oriented modeling for variability management

In product line development (PLD), reusability is the key factor, and it is important to make architecture and components flexibly configurable. Thus far, several techniques for utilizing aspect-oriented technologies (AOTs) for PLD have been proposed. However, the application of AOTs to PLD is not simple and various issues related to the application, such as an invasive change problem that prevents reusability, have been reported. We have proposed an aspectoriented modeling (AOM) mechanism that separates concerns from their relationships with other concerns. In this study, we propose the application of our AOM to variability management and demonstrate the effectiveness of our approach with the help of a case study of embedded software.
