Order picking has long been identified as the most labour-intensive and costly activity for
almost every warehouse; the cost of order picking is estimated to be as much as 55% of the …

In this paper we present a reference framework and a classification of warehouse design
and control problems. Based on this framework, we review the existing literature on …

Automated Storage and Retrieval Systems (AS/RSs) are warehousing systems that are used
for the storage and retrieval of products in both distribution and production environments …

This paper investigates the effectiveness of designing warehouses to determine average
order picking time and travelled distance using a data mining technique. Order picking is a …

We present a literature survey on methods and techniques for the planning and control of
warehousing systems. Planning refers to management decisions that affect the intermediate …

A travel time model with general item location assignment in a rectangular warehouse
system is presented. We give the exact probability mass functions that characterise the tour …

New types of Automated Storage and Retrieval Systems (AS/RS) able to achieve high
throughput are continuously being developed and require new control polices to take full …

Order picking has been considered as the most critical operation in warehousing. Recent
trends in logistics demand faster but more reliable order picking systems. The efficiency of …

This paper studies an integrated human-robot routing problem arising in collaborative order
picking systems. Travelling routes of pickers and robots interact with each other and …

In this paper, we consider a newly designed compact three-dimensional automated storage
and retrieval system (AS/RS). The system consists of an automated crane taking care of the …
