Travel Time Modeling and Simulation of a Mobile Racks Automated Storage/Retrieval System

Amine Hakim Guezzen, Zaki Sari, Pierre Castagna, and Olivier Cardin
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.
