A Fuzzy Implementation for Optimization of Storage Locations in an Industrial AS/RS
Warehousing is commonly used in factories for the
storage of products until delivery of orders. As the amount of
products stored increases it becomes tedious to be carried out
manually. In recent years, the manual storing has converted into fully
or partially computer controlled systems, also known as Automated
Storage and Retrieval Systems (AS/RS). This paper discusses an
ASRS system, which was designed such that the best storage location
for the products is determined by utilizing a fuzzy control system.
The design maintains the records of the products to be/already in
store and the storage/retrieval times along with the availability status
of the storage locations. This paper discusses on the maintenance of
the above mentioned records and the utilization of the concept of
fuzzy logic in order to determine the optimum storage location for
the products. The paper will further discuss on the dynamic splitting
and merging of the storage locations depending on the product sizes.
