DETERMINATION OF STOCK LEVELSDETERMINATION OF STOCK LEVELS
Minimum levelMinimum level
Minimum level quantity that must be maintained, Minimum level quantity that must be maintained, at all times if the stock holding falls below this at all times if the stock holding falls below this level, production stops due to shortage of level, production stops due to shortage of materials. This level is fixed, considering the materials. This level is fixed, considering the following factorsfollowing factors
1.Lead time1.Lead time
2.Rate of consumption. Nature of materials2.Rate of consumption. Nature of materials
•FORMULA FOR COMPUTATION OF MINIMUM STOCK IS:-minimum stock level-
•Re ordering level-(normal consumption*Maximum re order period)
B)B)REORDER LEVEL:-REORDER LEVEL:-When the stock level When the stock level reaches the re ordering level, the order is placed reaches the re ordering level, the order is placed
for replenishment of stocks. This level is fixed for replenishment of stocks. This level is fixed between the maximum stock and minimum stock.between the maximum stock and minimum stock.
THE FORMULA FOR CALCULATION IS:-THE FORMULA FOR CALCULATION IS:-
REORDERING STOCK LEVEL: Maximum consumption per day * Maximum re order period
MAXIMUM LEVELMAXIMUM LEVEL: : It is the level, beyond which It is the level, beyond which the stock level should not exceed. If this level is the stock level should not exceed. If this level is exceeded, there would be blockage of working exceeded, there would be blockage of working

2.2.Carrying costs: Carrying costs: These are the costs for These are the costs for holding inventories. Higher the stock holding, holding inventories. Higher the stock holding,
larger would be carrying costs and they would be larger would be carrying costs and they would be lower if the stocks are lower.lower if the stocks are lower.
The economic order size of inventory The economic order size of inventory brings a trade off between carrying costs brings a trade off between carrying costs

C= Inventory carrying costs, per one unit
GRAPHICAL PRESENTATION OF EOQGRAPHICAL PRESENTATION OF EOQ
The EOQ model can be presented graphically. To The EOQ model can be presented graphically. To explain it, there is example of placing an order of explain it, there is example of placing an order of mangoes. if annual consumption of an item is mangoes. if annual consumption of an item is 1000 units and order is placed for 200 units, each 1000 units and order is placed for 200 units, each time, orders have to be placed five times in a time, orders have to be placed five times in a year. If we increase the size of the order from 200 year. If we increase the size of the order from 200 to 500 units, the number of orders has to be to 500 units, the number of orders has to be reduced from 5 to 2. The ordering costs would be reduced from 5 to 2. The ordering costs would be lower for two orders, compared to five orders. In lower for two orders, compared to five orders. In other words, with the increase in size of the other words, with the increase in size of the order, total ordering cost would reduce..order, total ordering cost would reduce..

ABC ANALYSISABC ANALYSIS
Under ABC analysis, the item is allocated to the Under ABC analysis, the item is allocated to the group, depending on the amount of attention it group, depending on the amount of attention it
deserves. ‘A’ group requires the maximum deserves. ‘A’ group requires the maximum concentrations of the finance manager. This concentrations of the finance manager. This
group constitutes a higher % in terms of value, group constitutes a higher % in terms of value, while it occupies lesser significance, in terms of while it occupies lesser significance, in terms of
