Abstract

Abstract The purpose of this study is to investigate the sensitivity of the Ovako working posture analyzing system. This paper also focuses on the identification of insensitive and highly sensitive posture zones. The OWAS sensitivity analysis, together with the ordinal regression analysis, offers deeper insights into the methodology for assessing posture. A full factorial design was used to account for all possible combinations of body members. To assess the sensitivity, one parameter of the body part was changed while other parameters were left unchanged to understand its effect on the output score. Combinations of postures in which no change was observed and corresponding ranges were noted. Posture ratings with sudden jumps were also noted. Ordinal regression analysis was performed to identify the body variable with the greatest impact and its weight in estimating the OWAS action category. Ergonomic practitioners can be made aware of insensitive and sensitive zones when assessing posture.

Ovako工作姿势分析系统(OWAS)的调查敏感性研究
摘要本研究旨在探讨Ovako工作姿势分析系统的灵敏度。本文还重点研究了不敏感和高敏感姿态区域的识别。OWAS敏感性分析与有序回归分析一起,为评估姿势的方法提供了更深入的见解。全因子设计用于考虑所有可能的身体成员组合。为了评估灵敏度,改变身体部位的一个参数,而保持其他参数不变,以了解其对输出评分的影响。没有观察到变化的姿势组合,并记录相应的范围。突然跳跃时的姿势评分也被记录下来。通过有序回归分析确定影响最大的身体变量及其在估计OWAS行动类别中的权重。人体工程学从业者在评估姿势时可以意识到不敏感和敏感的区域。
