基于IE方法的电梯限速器参数校准工作站改善
Improvement of Elevator Speed Limiter Parameter Calibration Workstation Based on IE Method

针对电梯限速器生产线参数校准工作站操作流程中存在的若干问题，提出采用IE方法对当前的工作站进行分析并改善。本文首先分析总结了现有工作站存在的问题，然后通过对检测人员的动作进行分解，使用模特排时法和人因工效分析法对该工作站进行分析，最后通过ECRS原则对该工位不合理的动作进行改善，改善后该工作站作业周期由原来的248 s缩减到208 s，既提高了生产效率，又降低了工人的劳动强度。
To resolve the problems existing in the parameter calibration workstation of the elevator speed limiter production line, the IE method is proposed to analyze and improve the current workstation. Firstly, the problems existing in the workstation was analyzed and summarized. Then, the motion of the inspectors was decomposed, and the workstation was analyzed by Modolar Arrangement of predetermind Time Standard (MOD) and human factor ergonomic analysis. Finally, ECRS principle was used to improve the unreasonable motion of the workstation. The working cycle of the workstation has been reduced from 248 s to 208 s after the improvement, which not only improves the production efficiency, but also reduces the labor intensity of workers.
