The increasing complexity of systems being developed requires engineers to review their practices to improve engineering efficiency and meet the needs of a competitive market.To answer these challenges, engineers have always reused their know-how. However, facing today's rising complexity, reuse has to be much more performant. That is why models supported by formal or semiformal languages are preferred to avoid the variability of natural languages interpretation. In this context, Model-Based Systems Engineering (MBSE) made it possible to change the engineering paradigm by proposing a unique, shared system model. To promote and ease MBSE adoption, reuse should be fostered to respect the engineer's working method. A promising method for reusing models is based on the pattern concept. Thus, this paper aims to review and evaluate the pattern concept as a means of transferring know-how and fostering reuse in an MBSE approach.

Know‐how reuse is an approach that has been always used by engineers to take advantage of their accumulated knowledge and practices. But, the difficulty to formalize and reuse expert know‐how is increasing alongside the complexity of systems. To deal with this challenge, this paper aims to open the way to new approaches of know‐how reuse, in order to improve engineering activities. For that purpose, it explores the capabilities of three reuse approaches (commercial off‐the‐shelf (COTS), set‐based design, and patterns), and their ability to be linked with a model‐based systems engineering (MBSE) framework.
