基于工业工程法的空调装配线平衡优化
Balancing Optimization of Air Conditioner Assembly Lines Based on Industrial Engineering Methods
摘要
Abstract
To address the efficiency loss caused by the low balancing rate of the assembly line in air-conditioning manufacturing,this study takes the assembly line of Company G as the research object and constructs a multi-dimensional optimization system based on industrial engineering methods.Through on-site investigation,it was found that the assembly line suffers from systematic issues such as imbalanced cycle time(balancing rate of 67.52%),high process dispersion(smoothness index of 41.25),and resource redundancy(equipment idle rate of 23.7%).Based on the"diagnosis-analysis-optimization"logical framework,the study employs stopwatch timing method for time measurement,identifying a bottleneck process of 105.8 s time-comsuption.Process reorganization is implemented following the ECRS principle,and workstation load balancing is achieved through matrix analysis.The two-handed operation analysis method is applied to optimize the operation sequence of bottleneck stations.Empirical validation shows significant improvements in efficiency indicators:the balancing rate increased by 16.9%to 78.96%,and the smoothness index decreased by 30.5%to 28.72.Resource optimization results are notable,with human and equipment configurations reduced by 8.3%(from 24 to 22 workers)and 11.8%(from 17 to 15 units),respectively.In terms of comprehensive benefits,the daily production capacity of a single line increased by 12.7%,and annual labor cost savings reached 376 000 yuan.The research demonstrates that industrial engineering methods have significant applicability in discrete assembly scenarios,and their integrated application model can provide systematic solutions for production line upgrades in manufacturing enterprises.关键词
