为了量化地评价航空紧固件生产流水线的平衡性并对其进行改善,对一种典型的航空紧固件生产流水线进行了分析,结合流水线平衡的概念和航空紧固件生产流水线的特点,通过公式推导建立了一套可以从不同角度量化评价流水线平衡性的指标体系,阐述了其应用的方法和可行性;通过对比几种当前主要的研究流水线平衡的方法,指出航空紧固件生产流水线的平衡更适合采用工业工程的方法进行分析;研究了平衡性改进问题的解决思路,指出瓶颈工序对流水线的平衡性有重要影响,通过缩短瓶颈工序的加工时间可使整条流水线的平衡性得到有效改善,同时也使流水线上各工序的加工效率获得显著提升。最后通过实例计算对以上理论和方法进行了应用和验证。

In order to quantitatively evaluate the balance of aviation fastener production line and improve it, a typical aviation fasteners production line is analyzed. Combining with the concept of streamline balance and the characteristics of aviation fasteners production line, a set of quantitative evaluation index system is established by means of formula derivation, through which the streamline balance can be measured from different angles, the method and feasibility of its application are also expounded. By comparing several methods of current research on streamline balance, a conclusion is drawn that the streamline balance of aviation fastener is more suitable for the method of industrial engineering in analysis; the solution of streamline balancing is studied, which points out that the bottleneck process has important influence on streamline balance. By shortening the processing time of a bottleneck process, the balance of the entire production line can be improved, and also a significant increase in efficiency is obtained for each process on the production line. Finally, the above theories and methods are applied and verified by calculation in an example.
