Abstract : Software families often rise from reuse practices as cloning existing software products which are then enhanced or pruned to fulfill new requirements. With time, these variants grow in number and in complexity, and become more and more complex to maintain. Software product line engineering gathers a set of methods that aims at facilitating the management and development of such collections of existing variants. Documenting variability is the central point of this paradigm; This variability is represented in variability models that support a large part of software product line engineering processes.The partial or complete migration from software families to a product line approach eases their exploitation.Reverse-engineering, modeling and managing variability are known as crucial tasks of the migration: therefore, numerous methods have been proposed to study descriptions of software families for this goal.Some of them are based on formal concept analysis, a mathematical framework for hierarchical clustering which organises set of objects and their descriptions in canonical structures highlighting naturally their commonalities and variability.In this thesis, we defend that formal concept analysis, more than a tool, is a relevant structural, reusable and extensible framework to study variability of software families.First, we propose an overview of variability information which is highlighted thanks to this framework, and we discuss its scope of applicability.We study the common points between the conceptual structures of formal concept analysis and variability models.Then, we show how to use these conceptual structures to support research and modeling operations.Finally, we broaden the scope of this study to take into account more complex information about extended variability.We evaluate our method on data taken from the SPLOT repository, fork-insight and product comparison matrices from wikipedia.
