| Abstract | Literature on the storage and order picking policies of a POB AS/ RS is
exiguous. Time-distance based storage policy is the only storage
policy mentioned in the literature. This study proposed an alternative
storage policy based on the concept of "Hinterland", which recognized
the fact that the items are retrieved from the storage rack in the
form of a tour. Another means of realising reductions in travel time
is through restricting the picking area. Four storage policies were
devised for picking area operation based on both Time-distance and
Hinterland. The order picking policy was formulated as a case of the
Traveling Salesman Problem.
The above policies ignored the fact some groups of items may be
requested together frequently in the orders retrieved from the rack. A
storage policy based on "Complementary Hinterland" was developed to
harness this grouping characteristic to attain lower travel times.
Implementation of this storage policy required the development of an
order picking policy based on the Traveling Purchaser Problem.
To evaluate the performance of the storage and order picking policy
combinations suggested, two simulation models, one for non-grouped and
the other for grouped order structures, were constructed. Each policy
was tested under a set of four different operation environments as
defined by the different system parameters. The results show that
savings of upto 75% are possible over random storage and random order
picking policies through the implementation of rational storage
policies. The study, besides furnishing a relative performance guide
for the policies evaluated, also provides an insight into the impact
of various system parameters on the performance of both storage and
order picking policies. |
