Question
Modelling a fixed cost problem as an integer linear program requiresGroup of answer choicesadding the fixed costs in the objective function.using 0-1 variables.using multiple-choice constraints.using LP Relaxation.
Solution
The correct answer is "using 0-1 variables."
Explanation:
In order to model a fixed cost problem as an integer linear program, you would need to use 0-1 variables. These binary variables are used to represent whether or not a certain action is taken (such as whether to open a facility or not), which incurs a fixed cost.
If the variable is set to 1, the action is taken and the fixed cost is incurred. If the variable is set to 0, the action is not taken and the fixed cost is not incurred. This fixed cost can then be included in the objective function, which might be to minimize total cost.
Adding the fixed costs in the objective function, using multiple-choice constraints, and using LP Relaxation are techniques that can be used in integer linear programming, but they are not specifically required to model a fixed cost problem.
