Product metamodel based on the coupling of the extended design matrix X -DSM and SysML formalism

This paper proposes an approach to semantic modeling of products based on an extended version of the DSM Design Structure Matrix (DSM), called here, X-DSM (extended DSM) and on the SysML formalism. This metamodel is intended to take into account the structural characteristics of the product and its behavior along the life cycle, from the design phase to its end of life. For that, first, we proposed 4 types of X-DSM matrices that are used to represent the components, design parameters, activities and the associated project's stakeholders. And then, we use SysML language diagrams to represent the behavioral views of the product at different stages of its lifecycle. The proposed metamodel complies with the SysML formalism including both the 7 UML4SysML views and 2 additional views aimed to the care of Specifications and Parametric settings. These last two views are key factors for modeling products with multiple configurations. In the second part of the article, we propose implementation architecture to exploit the functionalities of such a metamodel in collaborative design.
