“…The high-level model proposed by Krichen et al 18 links dynamic reconfiguration process, represented by mode, transition, event, condition and action, to the structural configuration of the system in terms of components, connections and interaction ports. To describe the system behavior, Witt et al 19 use concepts such as states, state machines, constrains, transitions and effects. This information corresponds to the dynamic aspect as they describe transitions and their causes and effects.…”

“…A software engineering general-and specific-purpose language, SysML 31 [12], was chosen to implement the ontology. Our decision was based on our review of ontologies for reconfiguration where UML and SysML have been widely used 18,19 [13], [14]. SysML is relevant to our specific context because it supports system models, structural and functional, and traceability matrices that are essential for reconfiguration purposes.…”

“…11 Several ontologies aiming at supporting system configuration and reconfiguration exist. [12][13][14][15][16][17][18][19][20][21][22] However, to the best of our knowledge, no system reconfiguration ontology that takes into account the overall system reconfiguration process exists. Considering reconfiguration from the systems engineering perspective allows for categorizing the reconfiguration data into three classes according to the triggering aspects: structure, dynamics and management.…”

System reconfiguration is essential in complex systems management, as it is an enabler of system flexibility and adaptability. It ensures system operation and increases reliability, availability, maintainability, testability, safety, and reuse of system entities and technologies. For the reconfiguration of a system in use, it is necessary to assess, in continuity, the system's state with regard to its context. Identifying data supporting system reconfiguration represents a major industrial challenge and is linked directly to the development of industrial reconfiguration tools. Reconfiguration tools are based on a data model, also called ontology, which represents key concepts of system reconfiguration and their relationships. A particular difficulty of developing the data model is the multi-domain nature of reconfiguration. Furthermore, it needs to address a considerable diversity of system types. Few publications propose an ontology supporting data identification and tool development for the entire process. Hence, in this paper we propose to formalize the system reconfiguration process and propose an overarching ontology, which we call OSysRec. This ontology considers data at the management, dynamics, and structure level. The proposed ontology has been developed based upon expert knowledge and several industrial uses cases. The OSysRec ontology allowed a better understanding of the reconfiguration process, and hence it can be deployed for developing efficient and effective reconfiguration tools at the industrial scale. The ontology has been tested on an industrial case study to validate the proposed approach.
