The document discusses various inventory management techniques. It describes different inventory classifications like ABC analysis which categorizes inventory into A, B and C categories based on value and usage. It also discusses inventory models like the economic order quantity model which determines the optimal order size balancing setup costs and carrying costs. Finally, it covers inventory strategies like vendor managed inventory where suppliers manage inventory levels at customer sites.
Inventory/Material Control and management : Cost AccountingGuru Aarat
This presentation would help understand what is inventory and inventory control and management . It would also help understand various terms necessary for material controlling such as EOQ, Minimum stock , Maximum stock, buffer stock , re order level etc.
After learning about the various terms ..the techniques of material control would be discussed and presented with suitable graphs and point wise explanations
hey friends, we know from earlier research that material control is the major component of cost. so, let us have a look at few tenchniques relating to material control

13. High, Medium and Low (HML)
classification
The items of the inventory are to be
listed in the descending order of the
unit value.
The HML analysis is useful for
keeping control over consumption at
departmental levels, for deciding the
frequency of physical verification,
and for controlling purchases
14. Vital, Essential and Desirable
(VED) Classifications.
based on criticality of the items and
its effect on other production
For V items, a large stock of
inventory is generally maintained,
while for D items, minimum stock is
enough
15. Scarce, Difficult and Easy to obtain
(SDE)
availability of items
vital to lead time analysis of
procurement
16. Fast-moving. Slow moving and
Non-moving (FSN) Classification
classification is based on the pattern
of issues from stores
In and out date of items are
evaluated.
The items are usually grouped in
periods of 12 months

18. INVENTORY MODELS
Deterministic models
• Economic Order Quantity (EOQ) model
• Sensitivity analysis
• A price-break Model
Probabilistic Inventory models
• Single-period inventory models
• A fixed order quantity model
• A fixed time period model
22. Economic Order Quantity (EOQ)
model
Economic order quantity
= (2 x setup cost x demand rate/
carrying cost)^0.5
Limitation of the economic order
quantity model is that the demands
remain constant throughout the year.
It is also necessary that the
inventory be delivered in full when
the inventory levels reach zero
29. EOQ Model with Price Breaks
Incremental units: discount is
applied to the additional units
beyond the breakpoint
All units: discount is applied to all
units beyond the certain level of
order
30. EOQ Model with Price Breaks
Total annual
cost
$3.2 /unit
$2.9 /unit
$2.8 /unit
Feasible cost
Order quantity
32. Fixed order quantity model
Item must have a reasonable stable usage
Lead time should not have radical variation
Supplier should be able to accept
irregularly timed and unscheduled orders
34. VENDOR MANAGED INVENTORY
(VMI)
the vendor (the Manufacturer) manages
the inventory of the distributor.
manufacturer has access to the
distributor’s inventory data used for
generating purchase orders
The manufacturer reviews this information
and decides when it is appropriate to
generate a Purchase Order

35. INVENTORY ON WHEELS
freight on board (FOB)
Rule of ownership
• FOB shipping point. If the shipment is
designated as freight on board (FOB)
shipping point, ownership transfers to
the buyer as soon as the shipment
departs the seller.
• FOB destination. If the shipment is
designated as freight on board (FOB)
destination, ownership transfers to the
buyer as soon as the shipment arrives at
the buyer.
