MBSE Strategies: Avoiding Cyclic Project Usage Dependencies by using Black Box and White Box Models

Every digital engineering framework and modeling approach will include benefits and concerns. It is important to customize the response, within reason and based on the available resources, to the needs of the project and contract. For this case, the consideration of a large, singular model was overturned for a distributed model. The potential for a cyclic usage, which can be catastrophic in both performance issues and data loss, was mitigated by an innovative approach that allowed for two (2) systems models – one (1) Black Box and one (1) White Box – using a novel model federation strategy. The concerns of having two (2) system models were mitigated via acceptance and understanding that each system model would play its part appropriately based on model function, system development, and contract deliverables.
