ABSTRACT
One failure in the production equipment may lead to disability of the equipment, even
shutdown of the whole assembly line, causing great loss. To guarantee continuity of
production, panies tend to keep spare parts inventory far more than that is actually
needed. On the other hand, inventory management groups usually focus their attention on
production part inventories which are more directly related to production and profits, and
spare parts- sometimes termed the "hidden inventory"-continue to be ignored. In fact,
inventory of spare parts often accounts for a considerable fraction of pany's total
inventory. The optimization of spare parts inventory will lower pany’s cost
significantly, hence sharpen it’petitive ability. One solution to this problem is
employing modern inventory theory to optimize the inventory and replenishment of spare
parts. A spare parts inventory decision support system based on information technology is
also helpful.
The dissertation firstly summarizes the characters of spare parts inventory management,
and the different pared with WIP inventory and production inventory. To offer
aid for decision on spare parts inventory controlling, this paper studies spare parts inventory
decision support system and
