裝配線平衡(Assembly Line Balancing)是指将生産工序合理分配給流水線上的各個工作站,使每個工作站的操作時間盡可能接近節拍時間(Cycle Time),從而消除瓶頸、減少閑置時間并提升整體生産效率的工業工程技術。其核心目标是實現生産流程的同步化與資源優化配置。
節拍時間(Cycle Time)
指連續完成兩個相同産品之間的時間間隔,由市場需求決定。例如:若日需求為480件,日工時為480分鐘,則節拍時間=480/480=1分鐘/件。
工作站(Workstation)
裝配線上執行特定工序的單元。平衡需确保各工作站總操作時間≤節拍時間,且滿足工序間的優先關系約束(如必須先安裝螺絲後噴漆)。
平衡率(Balance Rate)
衡量平衡效果的指标,計算公式為:
$$ text{平衡率} = frac{sum text{工序時間}}{text{工作站數} times text{節拍時間}} times 100% $$
平衡率越接近100%,說明閑置時間越少。
根據問題複雜度可分為兩類方法:
適用于工序時間确定、無并行工作站的情況,常用啟發式算法(如Kilbridge-Wester法、最大候選規則)或精确算法(分支定界法)。
處理工序時間波動、多品種混産等複雜場景,需結合仿真優化或遺傳算法(來源:國際期刊《International Journal of Production Research》)。

- 豐田生産體系(Toyota Production System)将産線平衡與JIT結合,案例詳見豐田全球官網生産體系介紹;
- 美國工業工程師學會(IISE)發布的标準指南《Assembly Line Balancing Techniques》提供方法論框架。
"assembly line balancing"是工業工程領域的專業術語,其含義和要點如下:
Assembly Line(裝配線)
Balancing(平衡)
裝配線平衡(Assembly Line Balancing, ALB)
指在流水線生産中,通過調整各工作站的任務分配,使每個工位的操作時間盡可能接近,從而消除瓶頸、提高整體效率的生産優化過程。
汽車工廠中,若發動機安裝耗時3分鐘,而車門裝配僅需1分鐘,則需将車門裝配工序拆分到3個工位,或合并其他短時任務,實現時間均衡。
提示:如需了解具體算法(如啟發式算法、遺傳算法等),可參考工業工程專業文獻獲取完整方法論。
