Identification of Bottleneck Equipment in Flexible Production Line Based on Constraint Theory and Comprehensive Bottleneck Index

摘要: 针对不同零件加工顺序的变化导致生产线设备资源与工艺路径配置不合理的问题，提出了一种基于约束理论(TOC)和综合瓶颈指数的柔性生产线瓶颈设备识别方法。通过分析柔性生产线的设备灵敏度和阻塞程度，构建瓶颈设备指数矩阵，并利用多准则决策分析方法(TOPSIS)计算各设备的综合瓶颈指数，从而精准识别到柔性生产线瓶颈设备，为工艺规划阶段提供有力支持，提高生产线整体效率。为验证方法的有效性，本研究通过仿真构建了多组生产顺序进行对比实验，结果表明该方法在不同加工顺序组合下均能稳定识别出关键瓶颈设备，可为工艺规划阶段的设备配置优化提供决策支持，减少生产线的调试周期。

Abstract: Aiming at the problem of irrational allocation of production line equipment resources and process paths due to changes in the machining sequences of different parts, a method for identifying bottleneck equipment in flexible production lines based on the theory of constraints (TOC) and the comprehensive bottleneck index is proposed. By analyzing the equipment sensitivity and obstruction degree of the flexible production line, constructing the bottleneck equipment index matrix, and calculating the comprehensive bottleneck index of each equipment by using the multi-criteria decision analysis method (TOPSIS), the bottleneck equipment of the flexible production line can be accurately identified, which can provide powerful support for the process planning stage and improve the overall efficiency of the production line. In order to verify the effectiveness of the method, this study constructs several groups of production sequences for comparison experiments through simulation, and the results show that the method can stably identify the key bottleneck equipment under different combinations of processing sequences, which can provide decision support for the optimization of equipment configuration in the process planning stage and reduce the debugging cycle of the production line.
