The MRP input listing the assemblies, subassemblies, parts, and raw materials needed to produce one unit of finished product is the:

A bill of materials contains a listing of all the assemblies, parts, and materials needed to produce one unit of an end item.

End item Alpha's product structure tree and inventory information are as follows: (A) If 50 units of Alpha are to be assembled, how many additional units of S will be needed? All parts can be ordered using lot-for-lot ordering, except M, which must be ordered in multiples of 40 units. [Hint: You don't need to do an MRP plan.] (B) An order for 100 units of Alpha is scheduled to be shipped at the start of week 9. When is the earliest that any particular component must be started so that the order for Alpha will be ready to ship? [Hint: You don't need to do an MRP plan.]

Lumpy demand for components results primarily from the periodic scheduling of batch production.

MRP can apply to services, especially when it is focused on: (I) work-in-process inventory. (II) finished goods inventory. (III) service components. (IV) materials that are part of the service process.

Refer to this product tree: If 17 Ps are needed, and on-hand inventory consists of 10 As, 15 Bs, 20 Cs, 12 Ms, and 5 Ns, how many Cs are needed?

_______ is choosing how many to order or make.

Bunny Helpers, Inc., has just received an order for 100 Deluxe Easter Baskets, which must be ready for delivery at the start of week 6. An MRP planner has prepared the following table showing product structure, lead times (orders are lot-for-lot) , and quantities on hand: $\begin{array} { c l l } \text { Deluxe Easter Basket BOM } & \text { Lead Time } & \text { On-Hand } \\\hline \text { Deluxe Easter Basket } & 1 \text { week } & 10 \\\text { Dark Chocolate Truffles (2 per) } & 2 \text { weeks } & 30 \\\text { Carved Chocolate Eggs (4 per) } & 1 \text { week } & 50\end{array}$ Each Deluxe Basket contains two dark chocolate truffles and four carved chocolate eggs; additionally one bottle of Alka-Seltzer is included for those who overindulge. What is the net requirement for dark chocolate truffles to fill this order?

In MRP, under lot-for-lot ordering, planned-order receipts are:

The gross requirements value for any given component is equal to the net requirements of that component's immediate parent multiplied by the quantity per parent.

MRP II is simply an improved version of MRP that processes more quickly and can plan for a larger number of end items.

Net requirements for component J are as follows: 60 units in week 2, 40 units in week 3, and 60 units in week 5. If a fixed-period, three-period lot-sizing method is used, what will be the quantity of the first planned receipt?

In MRP, EOQ models tend to be less useful for materials at the lowest levels than for upper-level assemblies of the bill of materials since higher-level assemblies have larger dollar investments.

MRP output reports are divided into two main groups, daily and weekly.
