基于模糊综合评判的职员办公椅工效学

An Ergonomic Research on the Staff Chair based on Fuzzy Synthetic Judgment

职员办公椅人机工效水平受多因素的影响,评价指标各不同。本论文基于多层次模糊综合评价理论和方法,通过对"椅与人的适应性"分析,建立了职员办公椅的工效学的评价指标体系,同时,运用该体系对A、B、C三类不同职员办公椅进行体验后实施综合定量化评价与分析。结果表明,A和B类椅处于一般等级水平,C椅处于好的等级水平,其评价结果与三类椅的客观实际情况相符合。该实例证明,此模型适合于职员办公椅工效学的评价,并以此为依据提出相应的设计改进策略。

The ergonomic quality of the office chair is influenced by many factors, and evaluation indexes are different.Based on the theory and method of multi-level fuzzy comprehensive evaluation, and according to the analysis of“adaptability of chair and person”, an index system for evaluating office chair ergonomics constructed by five first-classindexes and twenty-four second indexes is set up to make quantitative evaluations of the efficiency of office chairergonomics. With this model, evaluation upon the expert experience on three different staff chairs A, B, C is made, and theresults show that the ergonomic quality of A and B is in common, while C is on good level, which proves to be in accordwith its actual situation. The examples show that this model is suitable for evaluating the level of ergonomics of the staffchair, and on the basis of the research, strategies for improvement are put forward
