DISCIPLINE-SPECIFIC MODELING
In complex systems design, models are not only used for documentation purposes but also for computer-based simulations allowing engineers to test system functions, validate requirements, detect design errors, and perform trade-off studies. Due to the complexity of each individual engineering discipline, engineers usually describe their knowledge in discipline-specific models. Examples of discipline-specific models are CAD models, dynamic system models and software models.
DEPENDENCIES BETWEEN MODELS
These discipline-specific models describe different aspects of the same system and therefore often share common information. As a result, discipline-specific models need to be viewed as a network of connected models in which a change in one model will have an impact on other models. The dependencies between the different models need to be formally defined in order to support traceability and consistency.
CENTRAL SYSTEM MODEL
A central system model can describe parametric dependencies between different discipline-specific models. This allows engineers to visualize how a parametric change in one model will influence parameters in other models. Parametric dependencies defined in the central system model can be automatically solved by third-party mathematical tools in order to ensure consistency within the central system model. Other third-party tools can then synchronize a change in parameters in the central system model with the other discipline-specific models in order to ensure consistency across all models.
SYSML-BASED CENTRAL SYSTEM MODEL
SysML is not only suitable for model-based systems engineering but also for the description of various discipline-specific models in a common central system model. Many discipline-specific models can be represented in a recognizable way in SysML allowing engineers to define dependencies between various discipline-specific models in a common central SysML model. Furthermore, SysML is an open standard in contrast to proprietary tool-specific modeling languages. As a result, engineers are able through a SysML-based integration framework to avoid tool vendor lock-in and save costs.
