针对以人为中心的动态服装装配过程，提出了一种装配线平衡优化模型。在劳动密集型企业中，由于作业人员效率的变化是导致生产线不平衡的重要因素，因此提出了一种考虑作业人员效率的最优作业人员配置方法来实现生产线平衡。两个递归算法的开发，以产生所有可行的解决方案的运营商分配。设计了作业效率标准差最小、生产线效率最高和总作业效率浪费最小的三个目标，寻求作业人员分配的最优解。该方法提高了对不同规模的操作数据集和操作算子分配的灵活性，提高了搜索大规模数据集最优解的效率。报告了实验结果。性能比较表明，所提出的优化方法优于工业实践。(c)2006爱思唯尔有限公司保留所有权利。
This paper addresses an optimization model for assembly line-balancing problem in order to improve the line balance of a production line under a human-centric and dynamic apparel assembly process. As the variance of operator efficiency is vital to line imbalance in labor intensive industry, an approach is proposed to balance production line through optimal operator allocation with the consideration of operator efficiency. Two recursive algorithms are developed to generate all feasible solutions for operator allocation. Three objectives, namely, the lowest standard deviation of operation efficiency, the highest production line efficiency and the least total operation efficiency waste, are devised to find out the optimal solution of operator allocation. The method in this paper improves the flexibility of the operator allocation on different sizes of data set of operations and operators, and enhances the efficiency of searching for the optimal solution of big size data set. The results of experiments are reported. The performance comparison demonstrates that the proposed optimization method outperforms the industry practice. (c) 2006 Elsevier Ltd. All rights reserved.
