The space market trends indicate that in the next decade, the space industry will continue to experience a radical transformation in terms of the number of operating satellites and market value. Simultaneously, Industry and Academia are leading a transition from Document-Based System Engineering to Model-Based System Engineering (MBSE), combined with Concurrent Engineering (CE) approaches, due to increased demand and reduced design time. How to effectively formalise data and improve data exchange is an open question. The representation of complex systems through models for defining their functional, logical, and physical architectures is not as straightforward as it could seem. For instance, during the Preliminary Design (PD) phase, when mathematical analyses and simulations need to be carried out, and system budgets need to be generated, such models require integration with external mathematical models that allow systems to be represented from a design parameters point of view.
