What is the relation between Architecting and Model-Based working?

Architecting is the activity to create and maintain an architecture. An architecture description captures the why, what and how of ways to create solutions for a given problem. An architecture relates the customer value proposition (desirability) and the business and life cycle proposition (viability to the system definition to the design and technology choices (feasibility). Architects make use of a rich palette of models.
In the past decades, researchers have proposed many forms of formal modeling to support specific design challenges. In Systems Engineering, there are high expectations of Model Based Systems Engineering (MBSE). What is the relation between architecting and MBSE?
