PLANNING MULTIPLE INVENTORY LOCATIONS

Supplying customer demand from comparable alternate inventory locations when an
item is out of stock at its primary stocking point creates a virtual inventory for that
item. The expectation is that if more inventories can be drawn upon, the inventory for
an item would be lower, the fill rate would be higher, or both. While generally true
that safety stocks will be lower, regular stocks, on the other hand, may rise with such
cross filling of demand. In this study, a methodology is developed that balances the
cross filling effects on both regular and safety stocks for determining whether an
inventoried item should be cross-filled. An example and guidelines are given to
show how the methodology can be simplified and applied in practice.
