Выражение встречается в следующем контексте:Space Allocation

The starting point for making the decision about how much space to allocate to each chain, sub-department or product group is by balancing the % of sales taken with the % of space given, for example:

• If Womenswear casual took 50% of Womenswear sales it should ideally be given 50% of the best selling space.

This equation should be the starting point for all of your departments.
The available space is calculated using carcase equivalents based on the fixtures detailed below:

Perimeter Carcase = 1
Gondola (Womens / Mens) = 2
Gondola (Childrens) = 2 (single) / 3 (double)
Till Queue Barrier = 0.25
Lingerie Tower = 1.5
Accessory Tower = 1.5
Clothing Tower = 1
Slate Panel = 0.5
