Which of the following statement regarding the W$-$W procedure is not true?

Group of answer choices

The W$-$W procedure assumed the demand is variable and deterministic.

To determine the optimal order quantity in the W$-$W procedure, we tradeoff between ordering cost and holding cost.

The optimal order policy in the W$-$W procedure will never order a fraction of the future demand.

The W$-$W procedure does not allow the ordering cost to be different from period to period.
