本研究探討周程時間最小化(Type Ⅱ)與工作負荷平滑化(Type Ⅲ)考量下之生產平衡效率問題。一般認為當以Type Ⅲ的目標之下應會有較佳的平衡效率產出，但本研究透過數值範例進行不同工作站數改變下的模擬情況，其結果發現當以追求Type Ⅲ為目標時，若工作站數給予過大的佈置空間，最佳佈置結果將傾向將生產周程時間加以放大，同時並進行工作單元的佈置調動，以達到各工作站平均負荷變異最小化的目標。因此，研究發現在工作站排給定條件下，兩個不同目標導向下，以Type Ⅱ為目標的生產線平衡問題之佈置有著較佳的平衡效率表現。

This study mainly investigates the efficiency of assembly line balancing (ALB) with the consideration of the minimization of cycle time (type Ⅱ) and workload smoothing (type Ⅲ). General researchers considered that the more workload smoothing makes the more ALB efficiency. Through the simulation of variable number of workstations, the ALB efficiency of type Ⅱ is often tie or ahead than type Ⅲ. The major finding of this work shows that the ALB solution of type Ⅱ is better than type Ⅲ under a given number of workstations. When the number of workstations is satisfied enough, the research suggested solution is going to type Ⅲ because type Ⅲ not only owns ALB efficiency and cycle time have insignificant difference than type Ⅱ, but creates the better workload smoothing. Therefore, the major finding of this work shows that the ALB solution of type Ⅱ is better than type Ⅲ under a given number of workstations.
