OPOL is developed for applications where another level of SKUs are called and control of
this level of SKU inventory is needed. Here the items stocked are variations of the basic
part (e.g., size, color, model, accessory) and these are the SKUs of concern. There are two
or more SKUs of this type for each part-location combination.
OPOL is used in situations where the units are stocked in stores or distribution centers in
various SKUs. Examples are, a style shoe with various sizes, sweaters with different colors
and sizes, various models and brands of a products (catsup, toothpaste, TV’s), accessory
items on bicycles, and so forth.
