1. A system, comprising: a memory configured to store a simulated model comprising a plurality of simulated components, each of the plurality of simulated components arranged in a component hierarchical graph such that a combination of the simulated components forms the simulated model; a processor that executes an inference engine configured to generate one or more redesign recommendations for at least one simulated component of the plurality of simulated components in the simulated model based on redesign recommendation rules and the at least one simulated component in the component hierarchical graph; and a display generator configured to display the redesign recommendations to a first user.
4. The system of claim 1 , wherein the redesign recommendations comprise displaying a list of choices for the first user to select; and wherein each choice is accompanied by numerical simulated results for the choice; wherein numerical simulated results for the component are displayed.
