Sorting and grading of wooden pallet parts are key factors for manufacturing quality and durable pallets. The feasibility of ultrasonic scanning for defect detection and classification has been examined in this report. Defects, such as sound and unsound knots, decay, bark pockets, wane, and holes were scanned on both red oak (Quercus rubra, L.) and yellow-poplar (Liriodendron tulipifera, L.) pa...

A study was performed to investigate how different types of handle coupling affect the loading on the spine. Ten male grocery item selectors performed a laboratory simulation of a warehouse palletizing task. Participants transferred the cases from a pallet in a storage bin to the destination pallet. The trunk motions and muscle activities were monitored by a Lumbar Motion Monitor (LMM) and elec...

Unit-load warehouses store and retrieve unit-loads, typically pallets. When storage and retrieval operations are not coordinated, travel is from a pickup and deposit (P&D) point to a pallet location and back again. In some facilities, workers interleave storage and retrieval operations to form a dual-command cycle. Two new aisle designs proposed by Gue and Meller (2006) use diagonal aisles to r...

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...

This paper is motivated by the problem of loading identical items of circular base (tubes, rolls, ...) into a rectangular base (the pallet). For practical reasons, all the loaded items are considered to have the same height. The resolution of this problem consists in determining the positioning pattern of the circular bases of the items on the rectangular pallet, while maximizing the number of ...

This paper utilizes the EPCglobal architecture framework to implement pallet management. Decision makers need to know every status of products in supply chain management, i.e., the visibility of products in the supply chain. The products always use the pallets as the carrying tools transported to various locations. If we want to understand the status of the products in the supply chain, first, ...
