lumix.goal_programming.objective_builder.combine_objectives(base_objective, goal_objective, goal_weight=1.0)[source]¶

Combine a base objective with goal programming objective.

This is useful when you have a primary objective function (e.g., maximize profit) and also want to incorporate goal constraints.

Parameters:

base_objective (LXLinearExpression) – Primary objective expression
goal_objective (LXLinearExpression) – Goal programming objective (sum of weighted deviations)
goal_weight (float) – Relative weight for goal objective (default: 1.0)

Return type:

LXLinearExpression

Returns:

Combined objective expression

Example

>>> profit_expr = LXLinearExpression().add_term(profit, 1.0)
>>> goal_expr = build_weighted_objective(relaxed_constraints)
>>> # Combine: maximize profit - goal_deviations
>>> combined = combine_objectives(profit_expr, goal_expr, goal_weight=0.1)
