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.

Domain analysis of dynamic system reconfiguration

A domain analysis of dynamic system reconfiguration is presented in this paper. The intent is to provide a comprehensive conceptual framework within which to systematically and consistently address problems and solutions related to dynamically reconfigurable systems. The analysis identifies and categorizes the various types of change that may be required, the relationship between those types, and the system integrity characteristics that need to be considered when such changes take place. A system model is employed to describe each change type using examples of global and local properties in the context of a financial analysis system. A rigorous formal methodology, based on the Alloy language and tools, is employed to specify precisely and formally the detailed relationships between various parts of the model. Based upon these descriptions, the types of change of dynamic system reconfiguration are presented as a series of UML class models.

“…Como fue mencionado anteriormente, el mecanismo de reconfiguración es ejecutado para cambiar la configuración de una arquitectura de control a través del uso de un modo de operación particular y parámetros de gobernabilidad específicos (ver Figura 14). La reconfiguración está basada en lo descrito por Walsh et al (2006) previamente, en donde únicamente se contempla un cambio decisional durante el proceso. Durante la ejecución, este mecanismo gestiona los procesos de reconfiguración y cambia a un modo de operación mejor adaptado a) como respuesta a la detección de una mejora o b) como respuesta a evento disruptivo.…”

Dado el continuo y acelerado crecimiento de la economía global, la producción mundial se ha visto afectada por un incremento significativo de recursos y energía. Este incremento ha traído diversos avances tecnológicos y digitales en el sector industrial que han evolucionado el área de sistemas de control reconfigurables. Específicamente, esta nueva tecnología ha surgido para dar respuesta a la volatilidad de sistemas de manufactura y satisfacer niveles adecuados de efectividad y reactividad. Sin embargo, los sistemas enfrentan el reto de generar un balance entre sus indicadores. En las últimas décadas, se ha visto la necesidad de incluir la sostenibilidad como una nueva métrica de eficiencia para los sistemas de manufactura. Igualmente, existe la necesidad mundial de incorporar la sostenibilidad en las operaciones industriales y se evidencia una falta de estudios en la integración entre productividad y sostenibilidad. Por esta razón, este trabajo de investigación propone un sistema de control con una arquitectura que hace el balance de eficiencia y efectividad entre indicadores de productividad y sostenibilidad. Dicho sistema propuesto consta de una arquitectura compuesta por distintos tipos de entidades. Así mismo, la propuesta también incluye un mecanismo de reconfiguración compuesto por tres módulos. Para mostrar los beneficios del sistema propuesto, se presenta la validación mediante la realización de experimentos en un ambiente simulado haciendo uso del software basado en agentes denominado Netlogo. Se evalúa la aplicación en un sistema de manufactura real ubicado en Francia. Como resultados, se evidencia que sí es posible integrar eficiencia y efectividad en un sistema de control. Esto mejora el desempeño de la energía hasta en un 69% y el del tiempo en 30%.
