ABSTRACT Customer references for the specification and design of industrial product systems are generally documentary, obtained by refining customer requirements. The increasing complexity of this specification process requires the migration to modeling using model‐based systems engineering (MBSE) processes and tools. MBSE‐based solutions proposed for product line management integrate a superset of modeled assets, also called a 150% generic model, to be selected and adapted for a particular product need. These solutions consider the modeling elements as basic elements of system specification, and do not address the constraint of secure access to confidential information. In this article, we propose another MBSE driven solution whose basic elements remain textual requirements, and allowing the modeling of product lines with access protection of confidential assets. We illustrate the approach through several examples, showing that it constitutes a relevant alternative to both Feature Model based solutions and Clone and Own practices.
