Before revision: This software approach is typified in CE-TOL aka TI-TOL, originally from ADCATS at BYU In the other, the variations are simulated by allowing random changes to geometry, constrained by expected distributions within allowed tolerances with the resulting parts assembled, and then measurements of critical places are recorded as if in an actual manufacturing environment.
