Abstract

The use of non-systematic reuse techniques in Systems Engineering (SE) leads to the creation of legacy products comprised of legacy assets like software, hardware, and mechanical parts coupled with associated traceability links to requirements, testing artifacts, architectural fragments etc. The sheer number of dierent legacy assets and dierent technologies used to engineer such legacy products makes reverse engineering of PLs in this context a daunting task. One of the prerequisites for reverse engineering of PLs is to create a family model that captures implementation aspects of all the legacy products. In this paper, we evaluate the applicability of a modeling paradigm called Multi-Level Modeling, which is based on the classinstance relation, for the creation of a family model that captures all the implementation concerns in an SE PL. More specically, we evaluate an approach called Multi-Level conceptual Theory (MLT) for capturing dierent legacy assets, their mutual relations and related variability information. Moreover, we map PL concepts like variants, presence conditions and product congurations to MLT concepts and provide formal interpretation of their semantics in the MLT framework. The illustrative example used throughout the paper comes from a real case from the automotive domain.
