COST - APMonitor Option

 Type: Floating Point, Input
 Default Value: 0.0
 Description: Cost weight: (+)=minimize, (-)=maximize

COST is multiplied by the MV or CV value 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.
