生產線通常以標準工人的平均時間為基準,安排作業時間相當的工作至每一個工作站,因而達到生產線平衡。但此種安排方式並未考慮到每站作業員的速度與標準工人並不相同,因而會影響整個生產效率。本研究透過兩次實驗,第一次實驗的目的是研究作業員的安置及工位設計對組裝線產量的影響,本實驗共召募6位屏科大學生參與實驗,每組為3人,每組均進行4次實驗(工位設計和作業員安置)。實驗結果發現:1.應按作業員速度去修改SOP,生產線較平衡及產能較高;2.快手安置在第一站比慢手按置在第一站,產能較多。第二次實驗的目的是驗證標準工時公式的準確性,本研究共計招募84位屏科大學生參與實驗,共28組,每組進行2次實驗(作業員安置),實驗結果發現:兩人線中,標準工時公式以平均數去預測實際時間較準確,推導公式預測時間與實際時間的絕對誤差在1.8%。
To assign equivalent jobs to every workstation to achieve line balancing based on the average time of standard workers. But these arrangements didn’t consider the different production rate between standard workers and other workers. Therefore it will affect the efficiency of the production line. Two experiments were held in the study. The first one investigates the effects of the placement of the operators and job design on the production quantity. 6 university students were recruited in the experiment and separated two groups. Each group performed 4 studies (two job design and two placements). The experiments show the SOPs should modify according to the individual production rate. Hence the line is balancing and with more parts produced. Place the faster operators in the first workstation, more parts produced. The second experiment was recruited 84 university students and separated 28 groups. Each group performed two studies. The major purpose of the experiment is to validate the standard time formula. The study shows using average time to predict the finish time for each part is better. The absolute errors between formula and the real time are only 1.8%.
