LEVERAGING MBSE USAGE THROUGH MODEL CHECKERS

Abstract System modeling is an essential part of the systems engineering process, helping with the design, analysis, and communication of complex systems. The usage of modeling languages like SysML and UML has become increasingly prevalent in this domain. To ensure the “3C” of validation of these models (correctness, completeness and consistency), model checkers play an important aspect. This paper discusses the role of model checkers in the validation of system models, and their importance in adopting MBSE approach with a quick benefit to system engineers. Different possible implementations are presented including one based on an ontology able to take advantage of semantic analyses. Finally, in order to deal with the number of issues due to the complexity of our models, we suggest correcting them regarding the goal of the model and the project milestones. This last point implies the need of an issue acknowledgement feature making it possible to justify the temporary or definitive rejection of these issues.
