Systems of Equations using Part Associations

Engineering problems and systems typically require detailed analysis to determine how a particular proposed solution will perform. The analysis can involve any number of equations that are often related to each other to determine a particular value.  Enterprise Architect allows an engineer to construct systems of equations using a Block Definition diagram and then to use these equations in multiple Parametric diagrams to describe proposed solutions.

This Block Definition diagram describes parameters of the straight line dynamics of a vehicle - the HSUV - and includes a number of equations that are represented on the diagram as Constraints, which are a type of Block.

The next diagram, a Parametric diagram, shows how the ConstraintBlocks are used in a particular context, being represented on the diagram as ConstraintProperties. We can visualize how the total power parameter is calculated, with a connection between the Power Equation and the equivalent parameter on the Acceleration Equation. Connections can be seen between the Position Equation and the Velocity Equation, which is ultimately connected back to the Acceleration Equation.
