Let c : E → {1, . . . , k} be an edge colouring of a connected graph G = (V,E). Each vertex v is endowed with a naturally defined pallet under c, understood as the multiset of colours incident with v. If δ(G) > 2, we obviously (for k large enough) may colour the edges of G so that adjacent vertices are distinguished by their pallets of colours. Suppose then that our coloured graph is examined b...

We consider the FIFO Stack-Up problem which arises in delivery industry, where bins have to be stacked-up from conveyor belts onto pallets. Given k sequences q1, . . . , qk of labeled bins and a positive integer p. The goal is to stack-up the bins by iteratively removing the first bin of one of the k sequences and put it onto a pallet located at one of p stack-up places. Each of these pallets h...

This paper analyses the influence of horizontal bracing restraints provided by the friction between pallet bases and rail beams on the static behaviour and design of steel drive-in storage racks. The pallet bracing restraints are shown to significantly influence the structural behaviour of the rack, and their effect on the bending moment distribution of the uprights is studied in the paper. The...

An estimated 4.53 billion board feet of solid hardwood and 1.79 billion board feet of solid softwood were used in the production of pallets and containers in 1995. When compared to estimates for 1992, the use of both softwoods and

A reconfigurable manufacturing system (RMS) is an advanced system designed at the outset for rapid changes in its hardware and software components in order to quickly adjust its production capacity and functionally. Among various operational decisions, this study considers the scheduling problem that determines the input sequence and schedule at the same time for a given set of parts. In partic...

Automated Guided Vehicles (AGVs) are used in warehouses, distribution centers and manufacturing plants in order to automate the internal material flow. Usually AGVs are designed to transport large and heavy transport units such as Euro-pallets or mesh pallets. Just-in-time inventory management and lean production requires small transportation units to enable one-piece-flow. A solution to meet t...

We consider the Distributer's Pallet Packing Problem. This problem is to pack a set of distinct products with given quantities in greater volumes (pallets, containers) and to minimize the number of used volumes. The theoretical objective of nding the best space utilization is restricted by a list of practical aspects (technological constraints, weight distribution over the pallet, stability asp...
