探討不同組裝線設計下對樂高模型生產績效之影響
The Study of Line Efficiencies on Different Types of LEGO Assembly Lines
摘要
在現代生產現場中的生產流程、生產系統設計與在製品的堆積，都可能會影響到產出情況，而實際的解決方式中，常利用生產線平衡的方式來改善此問題。因此本研究針對不同的組裝線進行產線規劃，將其分為大線、中線與小線三種，共招募107位屏科大學生參與實驗，進行在不同組裝線種類下，組裝兩種複雜度不一的產品的實驗。而本研究目的為探討不同組裝線設計與產品種類下，對於配料計次、產量紀錄、生產總值、產量、良品率、在製品與總配料數等生產績效的變化。實驗結果發現，中線生產模式對於生產總值與產量的績效表現較好，在製品量與配料數也適中；而大線生產模式的組裝線較不易平衡，導致在製品量較多，但配料次數比較少，在組裝較複雜的產品時採用此種生產模式，對於產量的表現較佳；最後小線生產模式的組裝線較易平衡，在製品量較少，但總配料數會較多。

The production process, the design of production system and the level of WIP are the major factors which affected the output. Arranged a banlanced assembly linecan solve the problem. Hence, the study aims at the impact of the assembly line sizes (large, middle, and small) on the productions of two different products. 107 students from National Pingtung University of Science and Technology were recruited in the experiment. The major purposes of the study are investigate the effects of assembly line types, product types on total production quantity(TPQ), total counts of feeding material(TCFM), TPQ and TCFM for every 10 minutes, defective rates, and WIP levels. The study found the middle line performs the best on TPQ+WIP, TPQ, and has a moderate level of WIP and TCFM. Large assembly line is more difficult to balance with more WIP but less TCFM. However, if the product being produced is more complex, then the bigger line is needed for bigger TPQ. Finally, the small line is easier to be balanced with smaller WIP but bigger TCFM.
