SysPEM: Toward a consistent and unified system process engineering metamodel

Industrial companies evolve in a highly competitive environment, their performance depends on their time to market as well as the quality of their products. This situation calls for a delicate optimization of supply chain and manufacturing processes, as a guarantee of the quality of the final system. Due to the fact that these processes are heterogeneous and poly-disciplinary, there is an urgent need for a general consistent model for all systems engineering concepts. Such model has to achieve an equilibrium between covering all key concepts of systems engineering processes and providing a rich language to express the details of these concepts. In this paper, we propose a solution to this problem through defining and validating a system process engineering metamodel inspired from research advances on Software Process Engineering Metamodel and System Modeling Language. The scope of this solution exceeds the definition and description of processes by providing an orchestration mechanism based on aspect oriented programming, in order to animate the execution control and monitoring through non intrusive mechanisms.
