In order to reduce production cost of enterprises and improve the level of lean production of enterprises, the wire harness production lines of an enterprise are studied, and the existing problems are analyzed by work-study methods (e.g., the theory of constraints and the ECRS principles).The operated objects of working stations are adjusted and the transport mode of finished products is improved.As a result, the number of operators is reduced in the working area, the idle time of operators is reduced, and the efficiency of the staff is improved.The method can provide reference for reducing the number of employees and improving production efficiency.%为降低企业生产成本,提高企业精益生产水平,以某企业线束生产线为研究对象,运用约束理论、ECRS原则等工作研究相关方法进行问题分析.通过调整工位作业内容,改进完成品的运输方式,取得减少生产区域人员数量、缩短操作人员空闲时间、提高综合人员效率的效果.研究方法对减少员工数量和提高生产效率具有借鉴作用.
