What is Inventory?
• Inventory is stock of items held to meet future
demand.
• It is a list for goods and materials, or those
goods and materials themselves, held available
in stock by a business.
• It is collection of goods processed to form
desired output to the organization.

• Raw Material Goods
– Basic inputs that are converted into finished product through the
manufacturing process.
• “Work in progress” Goods
– Semi-manufactured products need some more works before they
become finished goods for sale.
• Finished Goods
– Completely manufactured products ready for sale.
• Supplied Goods
– Office and plant cleaning materials not directly enter production but
are necessary for production process and do not involve significant
investment.

Types of Inventories contd.
6/10/2012
What is Inventory Management?
• Inventory management is all about specifying the size and
placement of stocked goods.
• It is required at different locations within a facility or within
multiple locations of a supply network to protect the regular and
planned course of production against the random disturbance of
running out of materials or goods.
• Inventory management also concerns with carrying costs of
inventory, asset management, inventory forecasting, inventory
valuation, inventory visibility, future inventory price forecasting,
physical inventory, available physical space for inventory.
67/10/2012
• Track inventory
– To look after the amount of inventory i.e. stock coming into the
business.
• How much to order?
– To specify units of inventory to be used by organization.
• When to order?
– Specify the duration of getting the inventory.

Inventory Management flow cycle
Raw Material  InspectionMoving Processing  Setup Final Product

Advantages of Inventory Management
• To decouple or separate various parts of the
production process.
• To split up the firm from fluctuations in demand and
provide a stock of goods that will provide a selection
i.e. variety for customers.
• To take advantage of quantity discounts.
• To survive against inflation.
97/10/2012
Inventory Management Models
For implementing specific model to any organization or
firm, we must determine when and how much inventory is to
be ordered.
Here is the classification of models,
• Basic Economic Order Quantity_EOQ
• Production Order Quantity_POQ
• Probabilistic Models and safety stock
107/10/2012
Basic Economic Order Quantity
model
• Demand of inventory is known, constant, and
independent.
• Receipt of inventory is instantaneous and complete.
• Quantity discounts are not possible.
117/10/2012
Production Order Quantity model
• Used when inventory builds up over a period of
time after an order is placed.
• Used when units are produced and sold
simultaneously.
127/10/2012
Probabilistic Models and Safety
Stock
• Used when demand of inventory is not constant or
certain.
• Demand may fluctuate over time due to seasonal,
cyclical and random influences viz. availability of
stock.
• Used for safety stock to achieve a desired service
level and avoid stock outs i.e. emptying of stock.
137/10/2012
reasons for keeping stock
To preserve the Inventory management, collection of
stock should be in solid state. Here are some reasons for
firms to keep the stock,
• Time
– The time lags present in the supply chain, from supplier
to user at every stage, requires that you maintain
certain amounts of inventory to use in this lead time.
• Variations
– Inventory is to be maintained for consumption during
'variations in lead time'.
147/10/2012
Reasons for keeping stock contd.
• Uncertainty
– Inventories are maintained as buffers to meet
uncertainties in demand, supply and movements of
goods.
• Economies of scale
– Ideal condition of "one unit at a time at a place, where
a user needs it, when he needs it" principle tends to
incur lots of costs in terms of logistics. So bulk buying,
movement and storing brings in economies of scale,
thus inventory.
