2.  Material Requirements Planning (MRP) is a
method that is used for planning, controlling, and
managing inventory items of goods (components)
which depends on the high items level (level).

3. To determine the need and schedule for the
manufacture of components and subassembly or
purchase materials to meet predetermined by the
MPS.
 Determine the need at the right time
 Determine the minimum requirement each item
 Determine implementation booking plan
 Determine rescheduling or cancellation of an
already planned schedule.

5.  Planning frame time (in a day,week,month
and other)

6.  Receipt schedule is the number of items that have
been purchased, but not fully accepted by the
buyer (Purchaser).
o The item is still being processed by the supplier,
o The item are being delivered to the Purchaser
o The item being examined by the admissions
department Purchaser

7.  For the final product, this value is taken from the
results of disaggregation, while at the level of item
lower, Gross Requirement for each period equal to the
item's (parent's) Planned Order Release level that is
above multiplied by the number / quantity for each
parent (usage ).

8.  Inventory on hand is the number of items into
inventory at the beginning of the period and the
expected quantity of inventory at the end of the
time period is 0.

9. Net requirement is that the actual quantity needed
to be accepted or produced in a particular period.
NR negative value indicates that no production is
required in a period ..

10. Planned order receipt is the number of items to be
received or produced at the end of the particular
period. Porc value depends on the determination of
lot sizing methods are used.

11. Is the number of items to be received or produced at the
end of a particular period of time taking into account the
lead time for each component.

12. Netting
• calculation process for determining the amount of net
requirements, which amount represents the difference between the
gross requirements with inventory
Lotting
• process to determine the optimal order quantity for each item
individually based on the calculation of net requirements that have
done
Ofsetting
• The final step is 'offsetting'. This determines when should start so that
the finished items are available when required.
Exploding
• the process of calculating gross requirements item/component

14. Lot For Lot
Economic Order Quantity
Least Unit Cost
Fixed Order Quantity

15.  Economic order quantity is the order
quantity that minimizes total inventory
holding costs and ordering costs. It is one
of the oldest classical production
scheduling models

16.  Lot for lot is a method for lot sizing, where the net
requirements occurring for each period are the
quantity of order. This method is often used mainly for
expensive items and the items whose demand occurs
intermittently. In this case the quantity is the same as
that of the case in which one period is specified in the
fixed period requirements.

17. approach aims to minimize the cost
of unit inventory
