On the Stability of Pallet Loading Layouts
نویسندگان
چکیده
The packing layout for loading boxes of identical format on a pallet can be determined algorithmically. This is important when performing automated packing by a robot. The well-known four-block heuristics and G4heuristics produce very efficient loading patters in most practical cases. In addition to the number of boxes on the pallet, one has to maximize the stability of the loading. This paper discusses the method of measuring the stability and proposes a modified set of stability rules giving more weight to the outer regions of the packing volume. Practical tests with the block heuristics reveal that the stability of the layouts may be extremely weak and caution should be taken when adopting their solutions in production.

Generating Stable Loading Patterns for Pallet Loading Problems
This paper describes an integer programming model for generating stable loading patterns for the Pallet Loading Problem. The algorithm always gives optimal or near-optimal utilization of the pallet area and fulfills stability criteria for 98% of the test cases.
متن کاملThe effects of operator position, pallet orientation, and palletizing condition on low back loads in manual bag palletizing operations.
Many mining commodities are packaged and shipped using bags. Small bags are typically loaded onto pallets for transport and require a significant amount of manual handling by workers. This specific task of manual bag handling has been associated with the development of musculoskeletal disorders (MSDs), especially low back disorders. This study evaluates the biomechanical demands of different wo...
متن کاملEffects of box features on spine loading during warehouse order selecting.
Low back disorders in distribution centres or warehouses have been identified as an area of elevated risk in many industries. The task of an order selector requires workers manually to lift boxes from storage bins to a mobile pallet. This study explored the effect of box features and box location when lifting from a pallet in a storage bin upon spine loading. Ten experienced warehouse workers w...

The present investigation presents a stochastic model for a flexible manufacturing system consisting of flexible machine, loading/unloading robot and an automated pallethandling device. We consider unreliable flexible manufacturing cell (FMC) wherein machine and robot operate under individual as well as common cause random failures. The pallethandling system is completely reliable. The pallet o...

In this paper the problem of calculating optimal packing patterns of small rectangles on a pallet is considered. We propose new heuristics which are based on the 4-block structure of packing patterns. Since, in general, for practical applications additional restrictio...
