In the field of materials management, Raw Materials, components and sub assemblies are kept on the basis of consumption. These inventories are maintained so long as it pays to keep.
Spare parts individually trifles. But also shortage and Non-availability of which will have much greater loss disproportion to their value.

4. Need for Scientific Management of Spare Parts:-
Factors Which call for scientific Management of Spare Parts:-
Random and unpredictable pattern of failure.
Long lead time required for procurement.
Non-availability of Special raw materials for manufacture of spare parts
High Tendency for obsolescence.
Most of the operating and maintenance personnel play safe and collect sorts of spare parts which may not be required for years to come.

5. Factors Influencing Spare Part Inventories?
Determination of type and quantity of requirement of spare parts can be based on precise knowledge of:-
