Sažetak

In the real manufacturing process the technological operation of sewing trousers side seams was recorded using a video system. Using modern methods of industrial engineering the structure of technological operation, workload (OADM) and share of unsuitable working postures (OWAS) were determined. It was found that at the existing workplace the unfavorable relationship of man-machine-environment leads to a high degree of workload caused by the forced position of spine and head, increased abdominal pressure, and reduction in visual skills and motor skills. Using the ERGOPlan software a redesign of the existing workplace was performed, and according to the anthropometric proportions of workers seating height, height of the machine work surface, working methods were determined, and using the method of predetermined times (MTM) the optimal working method with associated time norms was determined. Dynamic and static simulation of performing the technological operation at the redesigned workplace shows that the work is done in an ergonomically favorable posture with considerably reducing workload, which results in increasing workplace productivity while reducing fatigue.
