國內汽車產業面臨市場飽和的瓶頸,各家汽車製造商不斷的推出新車種及降低生產成本,以維持市場佔有率。本研究主要探討如何在生產線車型漸趨多樣且少量化下,藉由成台套零件供補(Set Pallet System, SPS)系統,來提高生產效率。 成台套零件供補生產方式是由專人以成台套的方式(每台車所需組裝之物料,皆放置在一訂製之容器內),依生產車序及時的供應給生產線上的作業員,能有效提高作業效率。借此種供補方式,有效減少生產線邊的物料擺放面積及改善作業效率。本研究以豐田生產系統的理念及價值溪流分析方式為工具,且適用於汽車製造業廠內SPS模式之作業流程,以利於汽車製造廠在生產車種日漸增加下,仍能有系統地規劃廠內零件供補作業模式,並作持續的改善。
The domestic auto industry is facing market saturation. Car manufacturers need to introduce new vehicles and reduce the cost to maintain market share. This study focuses on the increase of production efficiency by using Set Pallet System (SPS) with improved material supply in vehicle assembly line for small volume and high variety demands. SPS uses the set pallet mode (placing all the required materials in a pallet set for each vehicle) to supply materials to production line workers quickly and efficiently depending on the production car sequence. It can significantly reduce the storage space along the production line for material storage and supply and improve operating efficiency. In this study, the Toyota Production System philosophy and value stream mapping tool were used, as it is suitable for automobile manufacturing plant SPS model processes. It helps to systematically plan factory parts for the fill mode of operation and continuously improve even when the number of vehicle models continues to increase.
