ERGO-MTM model: an integrated approach to set working times based upon standardized working performance and controlled biomechanical load

摘要: ERGO-MTM is an innovative model to set standard times of manual tasks. MTM, developed in the forties by industrial engineers, assigns a basic time execute given motion based on concept normal performance (speed, effort and precision). The traditional models then add fatigue allowance, applied each individual motion, depending generally type posture load/force implied motion. To light most recent ISO/CEN standards dealing with biomechanical load, do not meet requirements any more: it becomes mandatory consider load generated overall assignment working tasks workstation be compliant new ergonomics standards. solution: determines allowance (named Ergonomic Allowance), which total MTM allow necessary recovery periods, enough keep within safety limits. final result norm level work sequence controlled load.
