Ankor is a wholesaler of tools and garden equipment, carrying such well-known brands as Skandia. Its warehouse is under continuous pressure to improve its efficiency while it is confronted with several special requirements in its order picking, like the requirement to retrieve heavy products first to prevent damage to other, breakable products.

Order picking – as a warehouse function – is often considered to be critical for the public manifestation of a supply chain. Underperformance can result both in unsatisfactory customer service and in high cost. In this paper the author will give an overview of planning problems and corresponding methods which have been suggested in the literature for the reduction of cost and the improvement of...

A recent trend in the layout design of unit load warehouses is the application of layouts without conventional parallel pick aisles and straight middle aisles. Two examples for such designs are flyingV and fishbone designs for single and dual command operations. In this study, we consider the same layout types under the case of multiple-item pick lists and show that, for both layout types, the ...

The Single-Picker Routing Problem deals with the determination of sequences according to which items have to be picked in a distribution warehouse and the identification of the corresponding paths which have to be travelled by human operators (order pickers). The Single-Picker Routing Problem represents a special case of the classic Traveling Salesman Problem (TSP) and, therefore, can also be m...

In this paper, we propose a prototype of a (collaborative) teleassistance system for mechanical repairs based on Augmented Reality (AR). This technology is generally used to implement specific assistance applications for users, which consist of providing all the information, known as augmentations, required to perform a task. For teletransmission applications, operators are equipped with a wear...
