Abstract : The design of complex systems goes through a multi-view paradigm in which separate teams, from different business viewpoints, build partial source models describing the system. As they are expressed in different languages, these partial models are called heterogeneous models. The main objective of this PhD thesis is to provide an approach that leverages collaborative engineering to ensure the overall consistency of heterogeneous source models. We first study the mechanisms offered by the existing approaches of model alignment. Then, we analyze the literature on modeling group decision-making. Based on this analysis, we have developed the meta-model MMCollab, a set of pattern-based group decision-making strategies and the two subprocesses of our approach called CAHM(Collaborative Alignment of Heterogeneous Models).The first subprocess targets the collaborative matching of source models; it formalizes the collaborative development of inter-model correspondences by offering a semi-automatic mechanism that reduces the involvement of business actors while ensuring the relevance and quality of the established model of correspondences.The second subprocess deals with the evolution of source models and meta-models, and mainly with the impact of these evolutions on the established model of correspondences. Consequently, this subprocess aims at maintaining the coherence of the overall system; it incorporates mechanisms to detect and calculate the impact of changes, as well as mechanisms and recommendations to collaboratively address inconsistencies that may occur.CAHM is based on two meta-models : A meta-model describing collaboration and group decision making in particular. This meta-model, called MMCollab, describes the fundamental concepts of a group decision-making and unfolds the phases of the constitution of collective decisions. The second meta-model is the MetaModel of Correspondences (MMC). This meta-model allows to define the structure of the model of correspondences, its correspondences and the relationships’ types that characterize those latter.The approach provides a support tool, called HMCS-Collab. Il allows unrolling CAHM’s subprocesses by integrating both alignment and collaboration aspects. It is based on the Eclipse platform and provides a web application allowing a lightweight execution of the approach by distant actors.
