Variability in activities and postures during electronic assembly work assessed by video-based analysis system: a preliminary study

Abstract [en]

The purpose of this study was to evaluate the variability of the analyst, the variability between and within operators by using a video-based computer analysis system. Activity and posture analysis were done. Three operators from an electronic factory participated who were performing manual assembly work at one workstaion. The results showed that the variability of the analyst was low. The variability between operators was higher than within operators’ variability. Sources of analyst’s variability came from the difficulty to see the operator’s hand in activity analysis, to see the reference point in the posture analysis. The variability between and within operators came from many sources: these were individual techniques, work sequences, work pace, work posture, and irregular events. The production system seems to be one of the possible sources of variability between and within operators. It can be concluded that it is enough to have one analyst and this method is adequate to examine the variability between and within operators in both activity and posture analysis in manual assembly work. The variability information from this study can be used to help to determine sampling strategies for future research.
