4. NEEDS OF INVENTORY
To make bulk purchase and get advantage of
discount
To maintain customer service level
To maintain continuous flow of supply through
supply chain
To achieve economy of scale in transportation
5. WHAT IS INVENTORY CONTROL
Its planning, ordering and scheduling of raw
materials
Right quality of raw materials available at right
time
Systematic control over purchasing, storing and
using of material.
6. FUNCTIONS OF INVENTORY CONTROL
Effective use of financial resources
Protection against all material losses
Proper calculation of cost of production
Keep the ball of production bouncing
Economies in purchasing
Eliminates redundant inventory
Keeping prompt delivery to the customers
7. SCOPE OF INVENTORY CONTROL
Formulation of relevant policies
Determining economic order quantity
Determining lead time
Minimization of material-handling and
storage cost
Ascertaining Safety Stock
8. MAIN TECHNIQUES IN SELECTIVE INVENTORY
CONTROL
ABC Analysis
GOLF Analysis
SOS Analysis
HML Analysis
SDE Analysis
FSND Analysis
9. CLASSIFICATION OF INVENTORY
Classification Full form Criterion employed
ABC Analysis Always Better Control Usage Value (i.e.
Consumption per period x
price per unit)
GOLF Analysis Govt, ordinary, local, foreign Source procurement
SOS Analysis Seasonal off seasonal Seasonality
HML Analysis High Medium Low Unit Price i.e. does not take
consumption into account
FSND Analysis Fast, slow, non-monetary,
material demands
Issues from store
SDE Analysis Scarce, difficult, easy Procurement difficulties
10. HML ANALYSIS
The cost per item (per piece) is considered for this analysis. High cost items (H),
Medium Cost items (M) and Low Cost item (L) help in bringing controls over
consumption at the departmental level.
Uses and application
•To assess storage & Security
Requirements
•High priced items in cupboards e.g.
bearings, worm wheels
•To keep control over consumption at the
departmental head level
•Authority to indents of High & Medium
priced items to departmental head after
careful scrutiny
•To determine the frequency of stock
verification
•checking frequency: more for high priced
items and less for L category
•To evolve buying policies to control
purchases
•Excess supply: Not accepted in case of H
& M category, Acceptable in case of L
category
•To delegate authorities to different
buyers to make petty cash purchase
•H & M by senior & L by junior buyers
11. FSN ANALYSIS :
This analysis is to help control obsolescence and is based on the
consumption pattern of the items.
The items are analyzed to be classified as Fast-moving (F), Slow-
moving (s)and Non-moving (N) items. The Non-moving items
(usually not consumed over a period of two years) are of great
importance. Scrutiny of non-moving items is to be made to
determine whether they could be used or be disposed off.
The fast and slow-moving classifications help in arrangement of
stock in stores and their distribution and handling methods.
12. SDE ANALYSIS :
This analysis is based on spares availability of an item –
S - refers to Scarce Items, especially imported and those which are very
much in short supply.
D - are Difficult items which are procurable in market but not easily
available. For example, items which have to come from far off cities or
where there is not much competition in market or where good quality
supplies are difficult to get or to be procured.
E - refers to Easy items – Items are those which are easily available; mostly
local items.
It is normally advantageous to consider A, V & S items for selective control
13. SOS ANALYSIS
SOS analysis is based on seasonality of items and it classifies all the items
into two categories ‘Seasonal ‘And ‘Off seasonal ‘
The analysis helps in:
Identifying items that are available only during a limited period of the
year .For e.g. Raw mangoes are only available only during a summers
Identifying items that are seasonal but available throughout the year
however their costs in offseason are relatively high.
SOS analysis can be selected when we want to determine the seasonality
of items and the right season for procuring them.
14. ABC ANALYSIS
Classifying inventory according to annual value
of consumption of the items
A - very important
B - mod. important
C - least important
Annual
$ value
of items
A

15. CONT..
When a large number of items are involved,
relatively few items account for a major part of
activity, based on annual value of consumption of
items.
It is based on the principles of ‘vital few and trivial
many’.
16. A-items : 15% of the items are of the highest value
and their inventory accounts for 70% of the total.
B-items : 20% of the items are of the intermediate
value and their inventory accounts for 20% of the
total.
C-items : 65%(remaining) of the items are lowest
value and their inventory accounts for the relatively
small balance, i.e.10%.
17. POLICIES FOR A
Develop class “A” suppliers more
Purchasing dpt makes maximum efforts to
expeditade and delivery of these items
The stock is maintained say in at least once in 15
days
18. Policies for B
Order quantities, re-order stocks and safety
stocks should be fixed and revised for B items say
once in 4-6 months
Should be ordered less frequently in comparison
to A items
19. Policies For C
Large quantities can be bought as the cost involved will
be least
Paper work is reduced if the stock is maintained and
ordered once or twice in a year
The source of their supply can be based on their
reliability

21. ADVANTAGES
Control
Cost
Improved service
warehousing
Allows a company to control over- supply and under-
supply of important SKUs
Once the company has decided which items fall into
ABC category it can establish cost reduction
initiatives at SKUs level.
•Improvement in customer service level and order
fulfilment.
•provides a company information to stock the right
mix of inventory.
•extends to warehouse management as well
•Companies utilizing ABC analysis in the warehouse
give priority space to faster moving SKUs
24. Control: Stocking a better mix of right inventory
allows a company to control over- supply and
under- supply of important SKUs
Cost: Once the company has decided which
items fall into ABC category it can establish
cost reduction initiatives at SKUs level.

26. APOLLO HOSPITALS
The basic principle of inventory control used by
Apollo hospitals is ABC based on cost criteria
Based on ABC matrix, the method that they use
is economic analysis of drug expenditure of
prised vocabulary of medical stores (PVMS)
27. Out of 493 drugs in PVMS section 1, only 325
were being used in reference hospital. The total
cost of drugs used was rupees 55,23,503
Out of these 325 drugs 47 (14.4%) drugs were
category A consuming 70% of total expenditure
73 (22.46%) drugs were category B consuming
20% of the expenditure
Rest 205 drugs (63.7) were category C drugs
consuming only 10% of the expenditure
