Modeling fixed costs as an integer linear program involves using 0-1 variables that reflect whether or not each cost is incurred. By using 0-1 variables, we ensure that each fixed cost is either included (1) or excluded (0) from the optimal solution, thus making the solution integer. Including the fixed costs in the objective function is not enough to model the problem as an integer linear program, as it would lead to a continuous solution. Multiple-choice constraints and LP relaxation are not relevant to modeling fixed cost problems.
