A Statistical Travel Time Model for Miniload Automated Storage and Retrieval Systems with Open-Rack Structure
In customary automated storage and retrieval systems (AS/RSs), stacker cranes (S/R machines) are used to store and retrieve loads into/from the storage cells. In this paper, the open-rack structure with unidirectionalupward mobile loads within the rack is applied in AS/RS, in which the stacker crane is only used for the retrieval operations, and the storage operations are carried out by separat...
متن کاملReducing Retrieval Time in Automated Storage and Retrieval System with a Gravitational Conveyor Based on Multi-Agent Systems
The main objective of this study is to reduce the retrieval time of a list of products by choosing the best combination of storage and retrieval rules at any time. This is why we start by implementing some storage rules in an Automated Storage/Retrieval System (Automated Storage and Retrieval System: AS/RS) fitted with a gravity conveyor while some of these rules are dedicated to storage and ot...
متن کاملDynamic Control of a Flow-Rack Automated Storage and Retrieval System
In this paper we propose a control scheme based on coloured Petri net (CPN) for a flow-rack automated storage and retrieval system. The AS/RS is modelled using Coloured Petri nets, the developed model has been used to capture and provide the rack state. We introduce in the control system an optimization module as a decision process which performs a real-time optimization working on a discrete e...
متن کاملMetaheuristic based control of a flow rack automated storage retrieval system
This paper presents two metaheuristic algorithms, namely taboo search and simulated annealing, applied to the control of a flow rack automated storage retrieval system (AS/RS). These metaheuristic algorithms are developed to control the retrieval machine of the AS/RS in order to minimize the retrieval cycle time. Results of these metaheuristic algorithms are compared to classical heuristics and...
