management
7. Economic order Quantity ( EOQ)
The economic order quantity is that
inventory level that minimizes the total
of ordering and carrying cost.
• Ordering cost
• Carrying cost
8. Methods to determine EOQ
Trial and error method
Order formula approach
Graphic approach
9. ABC inventory control system
ABC ( Always Better Control ) is a method
used to have an effective control over
inventories.
It is also known as control by importance and
exception ( CIE ) or proportional value
analysis
( PVA )
10. Steps in implementing ABC
analysis
1. Classify the items of inventories based on
their units and the unit price
2. Determine the total value of each item by
multiplying the no of items with unit price
3. Rank the items based on their total value
4. Compute the % of total value of each item
to total value of all items
11. Steps continued…
5. Compute the percentage of total value of
each item to total value of all items
6. Cumulate the percentages of items
7. Combine items and categorize them as
A,B,C etc.
12. Benefits
It ensures control over costly items
Stock is maintained at optimum level
It ensures reduction in storage expenses
It helps in maintaining enough safety stock
for C category items
