SELECTIVE INVENTORY CONTROL
• Selective Inventory Control is defined as a process of classifying items into different categories, thereby directing appropriate attention to the materials in the context of company’s viability.

ABC Classification System (Cont’d)
• 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’.
![Page 11: EVALUATION OF INVENTORY CONTROL](https://reader034.vdocuments.site/reader034/viewer/2022052321/55493049b4c90547498c366d/html5/thumbnails/11.jpg)
ABC Classification System (Cont’d)
• 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%.
![Page 12: EVALUATION OF INVENTORY CONTROL](https://reader034.vdocuments.site/reader034/viewer/2022052321/55493049b4c90547498c366d/html5/thumbnails/12.jpg)
Procedure for classification
• All items used in an industry are identified.• All items are listed as per their value.• The number of items are counted and
categorized as high, medium and low-value.• The percentage of high-, medium- and
low- valued items are determined.
![Page 13: EVALUATION OF INVENTORY CONTROL](https://reader034.vdocuments.site/reader034/viewer/2022052321/55493049b4c90547498c366d/html5/thumbnails/13.jpg)
V-E-D Classification
• Based on the critical nature of items.• Applicable to spare parts of
equipment, as they do not follow a predictable demand pattern.• Very important in hospital
pharmacy.
![Page 14: EVALUATION OF INVENTORY CONTROL](https://reader034.vdocuments.site/reader034/viewer/2022052321/55493049b4c90547498c366d/html5/thumbnails/14.jpg)
V-E-D Classification (Cont’d)
• V-Vital : Items without which the activities will come to a
halt.• E-Essential : Items which are likely to
cause disruption of the normal activity.
• D-Desirable : In the absence of which the hospital work does not get hampered.
![Page 15: EVALUATION OF INVENTORY CONTROL](https://reader034.vdocuments.site/reader034/viewer/2022052321/55493049b4c90547498c366d/html5/thumbnails/15.jpg)
H-M-L Classification
•Similar to A-B-C analysis. But it doesn't depend on annual consumption. The items listed out in decreasing order of unit value.H-HighM-Medium L -Low
![Page 16: EVALUATION OF INVENTORY CONTROL](https://reader034.vdocuments.site/reader034/viewer/2022052321/55493049b4c90547498c366d/html5/thumbnails/16.jpg)
F-S-N Classification
• Takes into account the distribution and handling patterns of items from stores.• Important when obsolescence is to
be controlled.F – Fast moving
S – Slow moving N – Non moving
![Page 17: EVALUATION OF INVENTORY CONTROL](https://reader034.vdocuments.site/reader034/viewer/2022052321/55493049b4c90547498c366d/html5/thumbnails/17.jpg)
S-D-E Classification
•Based on the lead-time analysis and availability.
S – Scarce: longer lead time(imported)D – Difficult : long lead time(indigenous)E – Easy : reasonable lead time
The items coming under S class are imported items, hence it has to be purchased once in a year or it may be an item which is not easily available in market.
![Page 18: EVALUATION OF INVENTORY CONTROL](https://reader034.vdocuments.site/reader034/viewer/2022052321/55493049b4c90547498c366d/html5/thumbnails/18.jpg)
S-O-S Classification
• S-O-S :Seasonal- Off- Seasonal• Some items are seasonal in
nature and hence require special purchasing and stocking strategies. • EOQ formula cannot be applied in
these cases. • Inventories at the time of
procurement will be extremely high.
![Page 19: EVALUATION OF INVENTORY CONTROL](https://reader034.vdocuments.site/reader034/viewer/2022052321/55493049b4c90547498c366d/html5/thumbnails/19.jpg)
G-O-L-F Classification
• G-O-L-F stands for:
G – Government O – Ordinary L – Local F – Foreign
![Page 20: EVALUATION OF INVENTORY CONTROL](https://reader034.vdocuments.site/reader034/viewer/2022052321/55493049b4c90547498c366d/html5/thumbnails/20.jpg)
X-Y-Z Classification
• Based on the value of inventory stored.
• If the values are high, special efforts should be made to reduce them.
• This exercise can be done once a year.
![Page 21: EVALUATION OF INVENTORY CONTROL](https://reader034.vdocuments.site/reader034/viewer/2022052321/55493049b4c90547498c366d/html5/thumbnails/21.jpg)
Importance of evaluation
• Inventory merely adds to the costs without in anyway creating value. This cost deserves to be eliminated. However, it is impossible to eliminate these costs, in the context of uncertainity of supplies. Therefore, these are controlled and evaluated for inventory performance.
![Page 22: EVALUATION OF INVENTORY CONTROL](https://reader034.vdocuments.site/reader034/viewer/2022052321/55493049b4c90547498c366d/html5/thumbnails/22.jpg)
Norms for inventories
For raw materials, consumables and components,
FIFO: First In First Out and LIFO: Last In First Out
are employed.• Under the FIFO method, the costs of items sold
in the current period are considered to be the earliest costs in inventory prior to the sale.
• For goods in transit, CIF: cost, insurance, freight value is utilized.
![Page 23: EVALUATION OF INVENTORY CONTROL](https://reader034.vdocuments.site/reader034/viewer/2022052321/55493049b4c90547498c366d/html5/thumbnails/23.jpg)
BASIS FOR CALCULATION
Inventory items
• Raw materials including components and other items used in the manufacture
• Work in process• Finished goods
Expressed in terms of
• Month’s or day’s consumption
• Month’s production
• Month’s production
![Page 24: EVALUATION OF INVENTORY CONTROL](https://reader034.vdocuments.site/reader034/viewer/2022052321/55493049b4c90547498c366d/html5/thumbnails/24.jpg)
INVENTORY TURNOVER RATIO
• Inventory turnover ratio(TO) or Stock turn rate(STR) is an expression used to show the relationship of inventories reported in rupees to the amount of goods.
• TO or STR = _Inventory__ Cost of goods• Inventory turnover ratio is an indicator
of inventory performance. • It indicates how many times the
working capital has turned over.
![Page 25: EVALUATION OF INVENTORY CONTROL](https://reader034.vdocuments.site/reader034/viewer/2022052321/55493049b4c90547498c366d/html5/thumbnails/25.jpg)
DIFFERENT TURNOVER RATIO
• Various turnover ratios can be separately calculated for raw materials, spare parts, components etc.
• Manufacturing materials: inventory as number of days of consumption.
actual inventory of manufacturing materials ×365
total consumption for the year
![Page 26: EVALUATION OF INVENTORY CONTROL](https://reader034.vdocuments.site/reader034/viewer/2022052321/55493049b4c90547498c366d/html5/thumbnails/26.jpg)
•Work in process(WIP): Inventory in terms of days of production at production costs =
actual work-in-process inventory ×365 total consumption for the year
•Finished goods: Inventory in days of sales at cost = actual finished goods inventory ×365 total consumption for the year
![Page 27: EVALUATION OF INVENTORY CONTROL](https://reader034.vdocuments.site/reader034/viewer/2022052321/55493049b4c90547498c366d/html5/thumbnails/27.jpg)
Importance of Inventory
• Faulty forecasting• Orders on unrealistic suppliers• Bureaucratic time consuming
procedures• Wrong transportation modes• Delays in imports• Machine imbalances• Poor maintenance
