5.2.3 Sizing of the storage zone....
Besides the material-handling systems and equipment, the capacity of the storage zone depends on the storage policy. In a dedicated storage policy, each product is assigned to a pre established set of locations. This approach is easy to implement but results in an underutilization of the storage space. In fact, the space required is equal to the sum of the maximum inventory of each product in time. Let n be the number of products and let Ij(t), j = 1,...,n, be the inventory level (in terms of storage locations) of product j at time t. The number of required
storage locations m in a dedicated storage policy is
