The total number of lockboxes is not a necessary constraint for identifying the optimal lockbox setup. It may be a constraint imposed by the problem statement, but it is not necessary for finding the optimal solution. The necessary constraints are A, B, and C. The decision variables must be binary because they represent whether a mailing zone is assigned to a lockbox or not. If a mailing zone is assigned to a lockbox, the cost function must include the fixed cost for that lockbox. Each mailing zone must be assigned to one lockbox to ensure that all mail is processed efficiently.
