What are Parametrics used for?
Parametrics insures data consistency within the SysML model and provides the potential for simulating model performance and comparing against system requirements. Possible usage areas:
Engineering projects: calculate cost, weight or power budgets, vehicle speed, component strength, and others.
Computer systems, calculate message traffic levels, database capacity needs, system availability, and others.
Business systems, calculate manpower needs or time to delivery.
Anything from "ballpark" estimates and "sanity" checks to detailed optimization, trade studies and sensitivity analysis can be organized throughout the development process.
