An experimental investigation on ergonomically designed assembly workstation

The main objective of this study was to investigate the effects of designing ergonomically assembly workstation on operator performance. This paper describes these results using factorial design of experimental which were conducted on assembly of a product. A fully adjustable ergonomically designed assembly workstation was used for the experiment. Ten college students were randomly assigned into three experimental factors or parameters (table adjustable, chair adjustable, and gender) to perform the assembly task. Performances of the participants assembling a product are: operator productivity (units/hour); operator satisfaction (degree of comfortable), and operator health (headache). The regression models to measure the operator performance were built based on the experimental investigation to suggest a practical performance measurement of operator. The results show that female subjects are more productive and healthy than male but with lesser satisfaction.
