Summary: Model-based systems engineering utilizes various model types with different accuracy levels, presenting a model fidelity hierarchy. By using the object-process methodology, errors can be detected and corrected through level transitions, providing maximum value with minimal effort. This continuous modeling approach allows for increasingly accurate error detection in the early stages of the system lifecycle, minimizing costs for corrections downstream.

Summary: SysML is a standard for systems-of-systems engineering that enables the description of complex system models but may not support all system engineering activities. This paper explores a declarative approach based on the QVT-R standard for transforming SysML models into executable simulation models. Methodological guidelines for effective use of a declarative language as QVT-R are provided, emphasizing the utilization of existing domain-specific SysML profiles and executable simulation library components.

Summary: In recent years, Model-Based Systems Engineering (MBSE) practices have been applied in various industries to design, simulate and verify complex systems. The verification and validation (V&V) of such systems engineering models are crucial to develop high-quality systems. To address the challenges posed by the complexity of models and semantic differences in interpretation, we propose a subset of the SysML language and a cloud-based V&V framework to achieve practical semantic integrity and scalability in industrial settings. We demonstrate the feasibility of our approach on an industrial-scale model from the aerospace domain and summarize the lessons learned during the transition of formal verification tools to an industrial context.

Summary: This paper presents a new approach for verifying consistency between process models, object life cycles, and context-dependent semantic action specifications. By involving declarative specifications of all the actions of a process and enforcing a subtyping relation for reuse, this formal consistency verification ensures that all involved specifications fit together procedurally and logically.

Summary: Global tectonics has evolved from intuitive guesses to a comprehensive understanding of Earth dynamics based on the plate tectonic concept and numerical simulations. A methodology is proposed to diversify classical models using the theory of multitudes, allowing for the inclusion of alternative theories and promoting consensus in the scientific community. This methodology is already available for use in geoscience and will further demonstrate its potential with the development of specialized software and web-based solutions.

Summary: Pediatric Failure To Thrive (FTT) is often missed or not diagnosed on time, which can affect infants' growth and development. We have developed FTTell, a model-based diagnostic tool for diagnosing FTT during pediatric follow up. FTTell calculates a score indicating FTT presence and severity and achieved an initial validity of 82%, improving to 87% after reassessment. FTTell can effectively serve as a diagnosis tool, improving pediatricians' correct diagnosis and timely intervention.

Summary: ISO/IEC/IEEE 15288:2015 is a crucial international standard in systems engineering, which meticulously models the major system lifecycle processes specified in 15288 and the objects interacting through them using OPM ISO 19450. The resulting OPM model serves as an exact, formal, and detailed expression of these processes and related objects, making it machine interpretable. The gaps discovered during the modeling process highlight the value of a model-based standards authoring approach and the importance of a formal yet humanly accessible model as the foundation for international standards and key technical documents.
