A comprehensive lifting model (CLM) for the evaluation and design of manual tasks was developed in two stages using 11 task, personal and environmental variables. In the first stage, the model was built using the psychophysical data. In the second stage, discounting factors of various variables were tested and adjusted using the physiological and biomechanical data. Two lifting indices are proposed to evaluate lifting tasks for a group of workers (relative lifting safety index or RLSI) and for an individual worker (personal lifting safety index or PLSI).
利用11个任务、个人和环境变量,分两个阶段开发了一种用于手动任务评估和设计的综合提升模型(CLM)。在第一阶段,使用心理物理数据构建模型。在第二阶段,使用生理和生物力学数据测试并调整各种变量的折扣因子。提出了两个提升指数,用于评估一组工人的提升任务(相对提升安全指数或RLSI)和单个工人的提升任务(个人提升安全指数或PLSI)。
