B.5.MPC.R:4.4 - Construct the repair that the receiving use needs

Choose the contribution that can remove the located incompatibility. The choice follows its cause and the wanted result.

• If the requested unknown changed, retain the interpreted relations, release the former fixed value where appropriate and derive the new computational direction.
• If a representation merged cases that the question must distinguish, retain the missing information, obtain a different observation or use a result that the merged representation still supports.
• If the procedure uses the wrong operation, constraint or approximation, replace that part and establish the property the receiving use needs.
• If the physical or measurement account omits a consequential interaction, model that interaction or change the arrangement so that the retained account applies.
• If execution differs in preparation, range, state or completion, revise that part of the realization or choose an available realization that supplies the required behavior.

An expression of an equation states a relation; an assignment or solver performs a chosen operation. Keep the equation’s meanings when generating or editing that operation. A modelling environment can help transform the equation system, but the physical interpretation and the requested result still guide the choice.

Compare the repair with a sufficient alternative. Changing a deadline may be cheaper than replacing an actuator. A useful ambiguity result may suffice before changing measurement equipment. Present a changed requirement as a choice for the receiving work.
