Active Validation
Active Validation is a key concept in Model-Based Systems Engineering (MBSE), which involves the continuous testing and validation-activity of a system model throughout its development and evolution. This refers to the process of continuously checking the consistency and accuracy of the system model, as well as the validity of the assumptions, constraints, and requirements that…

Schema
In the context of model-based systems engineering (MBSE), a schema refers to a visual representation or blueprint of how a model captures system components and their relationships. Often used to describe and organize the design of the system model. The schema provides a high-level overview of the system and its architecture, which can be used…
