2. INTRODUCTION
 Inventory-A physical resource that a firm holds in stock
with the intent of selling it or transforming it into a more
valuable state.
 Inventory System- A set of policies and controls that
monitors levels of inventory and determines what levels
should be maintained, when stock should be replenished,
and how large orders should be placed.

3. Items carried in inventory can be
 Raw materials
 Purchased parts
 Components
 Subassemblies
 Work-in-process
 Finished goods

4. Reasons for keeping Inventories
 To stabilise production
 To take advantage of price discounts
 To meet the demand during the
replenishment period
 To prevent loss of orders(sales)
 To keep pace with changing market
conditions

5. Objectives and Benefits
Inventory control aims at keeping track of
inventories. In other words, inventories of
good quality and right quantities should be
made available to different departments as
and when they needed.

6. COSTS ASSOCIATED WITH INVENTORY
 Purchase (or Production) cost
 Capital cost
 Ordering cost
 Inventory carrying costs (holding
costs)
 Shortage cost

7. Inventory Planning and Control
For maintaining the right balance between high
and low inventory to minimize cost

 Usage rate
 Procurement difficulties, criticality, frequency of
usage

15. SELECTIVE CONTROL OF INVENTORY
 ABC analysis
 VED Analysis
 Material requirements planning (MRP)

16. CONCLUSIONS
 Careful classification of your inventory, and
continuing analysis of those classifications, can play
a vital role in maintaining cost at the efficient levels
you have established as your goals
 Inventory control is a constant requirement of doing
