生產線平衡一向是產線要提升生產力的重點,其焦點多放在改變工廠內生產設備的排列及物料搬運、儲存方式的改善,對於作業員生產速度及位置遠近的探討並不多,而本研究以實驗方式探討這些因子對產能、良率及在製品的影響。 本研究的結論歸納如下: 1.以產能最大化為目標時: 近距離作業產能大於遠距離作業位置。 近距離作業,其工作指派為快手、慢手、中手組合排列。 遠距離作業,其工作指派為中手、快手、慢手組合排列。 2.當被要求以良率最佳化為目標時: 遠距離作業良率高於近距離作業位置。 近距離作業,其工作指派為慢手、中手、快手組合排列。 遠距離作業,其工作指派為快手、慢手、中手組合排列。 3.當被要求以在製品最低量為目標時: 近距離作業在製品量低於遠距離作業位置。 但無論是近距離作業或是遠距離作業,其工作指派都是以慢手、快手、中手組合排列。
Assembly line balancing is the key of increasing productivity. There are many studies were focused in changing layout of machines, resorting material handling or storage flows. Few articles concentrate on the effects of operators’ working speed and the distance among operators. In this research, the effects of working speed and distance on productivity, yield and WIP levels would be discussed. The results for this study are as follow: 1. Maximum productivity: The productivity to arrange operators side by side is bigger than to arrange operators seated with distance. A quicker operator is assigned first, then an average operator and the slowest operator when the distance among operators is side by side. An average operator is assigned first, then a quicker operator and the slowest operator when there is distance among operators. 2. Maximum yield: The yield to arrange operators side by side is smaller than to arrange operators seated with distance. A slowest operator is assigned first, then an average operator and the quicker operator when the distance among operators is side by side. A quicker operator is assigned first, then a slowest operator and the average operator when there is distance among operators. 3. Minimize WIP levels: The WIP levels to arrange operators side by side are smaller than to arrange operators seated with distance. A slowest operator is assigned first, then a quicker operator and the average operator when the object of the process is to minimize WIP level no mater what distance among operators.
