COST is multiplied by the FV, MV, or CV and the product is included in the objective function to favor maximizing (-) or minimizing (+) that quantity. It is important that the relative magnitude of each term in the objective function is scaled appropriately to ensure that the optimizer achieves a solution that is overall optimal with weighting that ranks the importance of each term. One method to appropriately weight values is to put COST in terms of monetary units.

COST is multiplied by the FV, MV, or CV and the product is included in the objective function to favor maximizing (-) or minimizing (+) that quantity. It is important that the relative magnitude of each term in the objective function is scaled appropriately to ensure that the optimizer achieves a solution that is overall optimal with weighting that is specifically desired.
