基于模块化的服装混合流水线平衡优化

针对服装生产存在的多品种、小批量、短周期等普遍现象,提出以模块化为基础的服装智能生产编排算法,以实现混合流水线下多款服装的快速生产。以服装模块划分为基础,建立模块化服装生产排序与工序分配的联合优化数学模型,设计目标追踪遗传算法求解模型,实现模块化服装在同一流水线上的投产排序优化及服装加工工序的自动化编排。以2款相近衬衫为例进行测试,结果表明:模块化服装混合流水线平滑系数和编制效率分别达到3.359和97.9%,相较于小批量的单件流生产,编制效率和流水线的平衡稳定性均有显著提升。本文研究可为服装智能制造与精益生产的推进提供理论参考。

Balanced optimization of garment hybrid assembly line based on modularization

Targeting at multi-variety, small-batch and short cycle features in garment production, a garment intelligent production scheduling algorithm based on modularization is proposed to facilitate rapid production of multiple garments on a hybrid assembly line. On the basis of garment modules, the joint optimization model was established including ordering production tasks and assigning modular garment production process. The target tracking genetic algorithm was designed to set up the model, to achieve the optimization of the production sequence and the automatic arrangement of the garment manufacturing process on the assembly line. Taking two similar shirts for examples, the smoothness index and line efficiency of the designed modular garment hybrid assembly line reach 3.359 and 97.9% respectively. Compared with single-piece flow production of small batch, the modular production has significantly improved the balance of the assembly line, providing theoretical guidance for the promotion of garment intelligent manufacturing and lean production.
