Abstract—AS/RS systems are devices designed for automated
storage and retrieval of parts and items in manufacturing,
distribution, retail, wholesale and institutions. This paper
consists in studying a storage system with Mobil racks
(M-AS/RS) which are a variation of the multi aisles AS/RS. This
mobile storage system is composed of racks moving laterally on
rails so that one can open an aisle between any two adjacent
racks, it makes it possible to optimize the use of space; the
characteristic of these systems is that the aisles of service appear
only when one operation of storage or retrieval is envisaged in
the corresponding racks.
One of the most important criteria of performances of these
systems is the average cycle time of the storage/Retrieval
machine.
In this paper our interest is concerned with the mathematical
modeling of M-AS/RS system. We presented a closed form
analytical expression allowing an approximate calculation of
the travel time of a Mobil Racks-AS/RS. This expression was
compared with simulation results and an exact discrete
expression developed earlier by one of the authors.
Index Terms—M-AS/RS, Mobil racks automated
storage/retrieval system, single and dual cycle times.
