Collaborative model-based matching of heterogeneous models

Abstract

Design of complex systems implies various points of view expressed by stakeholders with different areas of expertise. Each stakeholder describes his model in a Domain Specific Language, according to his point of view. Ensuring the consistency of the global system and building a cross view is a challenging task. It requires the involvement of all stakeholders to produce intermodel correspondences that satisfy their concerns. In this paper, we first introduce a metamodel of collaboration that formalizes collaborative work, then we use this metamodel to define a collaborative process for heterogeneous design models matching. This approach establishes semantic links at metamodel level by following a group decision-making process, then it refines those links semi-automatically at model level by exploiting their semantics.

A Collaborative Decision Approach for Alignment of Heterogeneous Models

“…It can be instantiated to describe each collaborative session where stakeholders make proposals, evaluate or refine them to come up with a collective decision. A description of the kernel of MMCollab was done in [10]. Since this release, we have structured MMCollab in packages and enriched it by adding the CollectiveDecision package which is dedicated to GDM.…”

“…Partial models describing this system were defined in cooperation with emergency doctors of a french hospital. We first present the ED, then recall the collaborative matching process proposed in [10] before applying it to ED system.…”

“…Thus, HMCS tool will keep only LLC1. In a same manner, LLC2 and LLC3 are kept at the end of the automatic process (for more information about this process, see [10]).…”

“…Furthermore, although industrial practices favour collaborative design, the collaborative alignment of heterogeneous models is still done, in practice, informally which is fastidious and error-prone. To cope with this need of collaboration, we proposed an approach for semi-automating the Collaborative Alignment of Heterogeneous Models [10]. It combines Model-Based Engineering (MBE) and Group Decision-Making (GDM) to establish and maintain correspondences among heterogeneous models.…”

“…It combines Model-Based Engineering (MBE) and Group Decision-Making (GDM) to establish and maintain correspondences among heterogeneous models. It is based on a metamodel of collaboration, called MMCollab and introduced in [10]. In this paper, we propose an extension of MMCollab by integrating co-decision policies.…”
