Abstract

Product Line Engineering (PLE) has been widely accepted as a representative software reuse methodology by using core assets. As a key element of core assets, product line architecture (PLA) should be generic to a set of applications in the product line (PL). However, the difference between PLA and single system architecture has not been treated well enough, so evaluating PLA still remains as one of the difficult tasks in PLE. In this paper, we identify two intrinsic but overlooked issues in PLA; variability propagation chain and conflicts between architectural elements. And, we present a metric-based methodto evaluate PLA from the perspective of the two issues. We believe that the two issues in PLA and the evaluation method would make designing high-quality PLA more feasible and effective.

프로덕트라인 공학(Product Line Engineering, PLE)은 여러 어플리케이션들이 공유할 수 있는 핵심자산을 사용하는 대표적인 재사용 방법이다. 프로덕트라인 아키텍처(Product Line Architecture, PLA)는 핵심자산의 주요 구성 요소 중 하나이다. PLA는 일반적인 소프트웨어 아키텍처와는 달리 한 프로덕트라인에 속한 여러 멤버의 공통성과 가변성을 포함하므로, 기존 아키텍처와는 다른 방법으로 평가되어야 한다. 그러나, 기존 연구는 PLA와 기존 아키텍처와의 차이를 충분히 다루고 있지 못하여 PLA 평가는 PLE에서 어려운 작업 중의 하나로 인식된다. 본 논문에서는 PLA 설계 시에 중요하게 다루어져야 하는 두 가지 이슈를 제안한 후 식별한 두 가지 이슈를 중점으로 PLA를 평가하기 위한 메트릭을 제안한다. 식별된 두 가지 이슈와 제안된 PLA 평가 메트릭으로 PLA를 효율적으로 설계할 수 있으며, 제안된 메트릭으로 아키텍처 설계자의 경험에 의해 수행되는 PLA 평가를 좀 더 체계적으로 수행할 수 있다.
