Estimating Storage Spaces Number

Dedicated & randomised storage policies are utilized to determine the number of storage spaces in AS/RS. In dedicated storage policy, a specific set of storage slots is allocated to a specific product. Therefore the sum of the maximum inventory levels for the total products match with the number of slots needed to store the product.

In case of randomised storage policy, any compartment in the storage aisle is uniformly probable to be choosing for transaction. Similarly, there is identical chance of each unit of particular product to be retrieved when a retrieval operation is performed. Therefore, in a long run, maximum of the aggregate inventory level of all of the products is taken into account for determining the storage space number.
