Final answer:
Lot-For-Lot ordering in MRP involves ordering materials based on exact production needs per period using forecasted demand, thus managing inventory levels to meet current and future orders efficiently.2) To extend beyond the orders already received
Step-by-step explanation:
The purpose of Lot-For-Lot ordering in Material Requirements Planning (MRP) is indeed all of the options listed: 1) To provide coverage for a specific number of periods, 2) To extend beyond the orders already received, and 3) To use forecasted demand. This ordering strategy aims at ordering exactly what is needed for production based on the current demand forecast, rather than ordering in larger quantities. This minimizes inventory holding costs and reduces the potential for excess inventory. By considering forecasted demand, the MRP can more accurately gauge future needs and plan production accordingly, ensuring that inventory levels are sufficient to meet both current and anticipated orders.
