本研究的主要目的是探討在作業員在不同情境壓力,並了解在製品量增減的情況,對其作業績效之影響。五種不同的情境壓力分別定義為 1.無壓力:此情境係指受試者依照自己的能力、速度拿取工件生產;2.快手-作業員-快手,3.快手-作業員-慢手,4.慢手-作業員-快手,5.慢手-作業員-慢手,所謂快手係指該作業員在無壓力情況下最快的生產速度,而所謂慢手是該作業員在無壓力情況下第70百分位的作業時間,快手及慢手的作業速度在實驗進行中維持固定。本研究共計招募十五位屏科大女學生參與實驗,其實驗結果如下: 1. 就產量而言,以情境快手-作業員-快手平均產出較高,但在無壓力下產出最低。 2. 就良率而言,建議前後皆安排慢手作業員,以利提升良率之產出。 3. 就WIP總量而言,慢手-作業員-快手的作業情境能有效降低 WIP,而快手-作業員-慢手會顯著提升WIP總量。
The main purpose of this study was to explore stress impact on job performance of "the Operator" in different stress situations by amount of work in process. There were five different stress situations, respectively. 1. no stress: this referred to operator in accordance with their abilities of speed of production, 2. quick worker-operator-quick worker, 3. quick worker-operator - slow worker, 4.slow worker- operator-quick worker, 5. slow worker- operator -slow worker. "Quick worker" mean workers at the speed of the fastest production under no stress situation. "Slow worker" mean the 70th percentile production speed under no stress situation. In the whole study, the quick or slow worker had contained their speed of production. This study recruited 15 university female students. The results of the experiment are the following: 1.The average production quantities are highest under quick worker-operator-quick worker situation and the lowest production quantities happen at no-stress situation. 2. Slow worker-operator-slow worker situation is the most suitable one if yield of the product is concerned. 3. Slow worker-operator- quick worker situation can reduced total WIP quantities significantly.
