Abstract

Abstract: While the Digital Twin is now well discussed in manufacturing, the research considering the Digital Twin of services engineering is still in its early stage. The Digital Twin is very focused on the manufacturing operations with gathering data from physical means and information technology. Yet, services are now features and core concerns of complex systems development. However, it is not much focused on services and above all workflow orchestration to deliver these services to user whether it is an internal operator, or a customer. The engineering of Digital Twin services is a complicated phase because of the complexity of interactions and heterogeneous nature of services. The simultaneous use of models and data (e.g., Model Based System Engineering (MBSE)) should be considered for service-oriented engineering projects of complex system (large system, heterogeneous components, autonomous, etc.). Based on this postulate, the contribution of this paper is about Digital Twin and MBSE for Servitization industry. In detail, the paper proposes a recall of information systems for enterprises, workflow and servitization. Then it draws some perspectives about the interest of Digital Twin approach based on models for product service systems. It discusses the relation between service twin and ground data and the link to decision level.
