Systems and associated methods for automated repair support for input model faults are described. Embodiments automate generation of fault repair support by producing one or more repair action suggestions for a given input model containing faults. Responsive to an indication of one or more faults within the model, embodiments utilize a fault index to ascertain the nature of faults within the model and to compile one or more repair action suggestions. Users can review the repair action suggestions, and preview the impact each of these suggestions will have on the model if implemented, and select an appropriate repair action for repairing a model containing faults.
