1. A computer implemented method for reconfiguring a model, said method [ 600 ] comprising: accessing [ 605 ] an instruction, wherein said instruction comprises utilizing one or more model elements to reconfigure a model; utilizing [ 610 ] a refinement chain to access a portion of said model, said portion being non-variable and associated with said instruction, and wherein said refinement chain tracks design changes for said model; locating [ 615 ] a specific instance closest to said portion within said refinement chain at which an inclusion of said one or more model elements alters a performance of said model to reflect said inclusion; and re-instantiating [ 620 ] said model utilizing said one or more model elements beginning at said specific instance, thereby enabling a re-configuration of said model according to said instruction.
