For the special discount, it is based on the total ordered amount or the lead time that you take as long as you meet the requirements. For example, the requirements said that $15\%$ off "over" $4-$week lead time. It means that any lead time for $4$ weeks or more will receive $15\%$ off. You can take both discounts, one discount, or none if taking this discount did not give you sufficient benefits in terms of productions. On the example above, your Receiving Department will be idle while waiting for your "raw" materials to be delivered on the week $5.$ You cannot produce your products until week $6$ since it takes at least one week $($i$.$e$.$ capacity is $500$ units per week$)$ to sort the materials. You still need to pay the workers and have other expenses while the department is idle, so please just take the special discount when it benefits you.$$
