Final answer:
In Material Requirements Planning (MRP), 'scheduled receipts' are A) open orders already scheduled to be delivered. They correspond to the ordered items that are expected to be received and are different from planned orders, net requirements, and gross requirements.
Step-by-step explanation:
In Material Requirements Planning (MRP), “scheduled receipts” are defined as A) open orders already scheduled to be delivered. Scheduled receipts represent the purchases and production orders that have been previously planned and are expected to arrive to fulfill the demand in the future periods specified. These differ from “net requirements”, which are the actual amount needed in each time period after considering the on-hand inventory and scheduled receipts. “Planned-order receipts” refer to the quantity of products expected to be received at the completion of a planned production order, which are not the same as scheduled receipts, as the latter are orders that have already been placed. Similarly, “planned-order releases” are the planned amount of orders that need to be released in order to meet the net requirements, which again differ from scheduled receipts that are orders already in process. Furthermore, scheduled receipts are distinct from “gross requirements,” which are the total demand for an item without accounting for inventory or orders in transit.
