摘要：This paper evaluates ergonomics indicators of order picking activities related to different pallet picking alternatives, namely a) picking from full pallets on the floor, b) picking from half pallets on the floor, and c) picking from half pallets on the upper rank of the shelf. The OWAS (Ovako Working posture Analysing System) index and the energy expenditure level are used to evaluate the different systems. The necessary data was collected in a field analysis using a motion capturing system. Mathematical models for the ergonomics analysis are developed and risk factors related to musculoskeletal disorders associated with the specific pallet picking system are discussed.
