Task assignments into an assembly line are based on the standard times of the task elements. The standard time of a task can be quickly obtained by applying the theory of learning curve. For performing a certain task, the learning effect of an operator which can be affected by blood types and motion classifications is discussed in order to facilitate the assignments of operators into an assembly line before establishing the standard time of a task. Therefore, an experiment and analyses of variance for the two factors, blood types and motion classifications, upon the learning effect of an operator are conducted. Based on the results, the learning effect of an operator is affected by blood types and motion classifications, but the interactions between the two factors upon the learning effect are not significant. According to the above consequences, the tasks on the line can be assigned appropriately to operators so as to promptly establish the task standard time and improve the line efficiency. |
