Abstract
In this study a relationship between the learning and the workload was examined after performing four experiments based on the working structure classification referring to the single works (the card classification test, the memory and operation test, and the both hands collaboration test) and the combination works (combination of those 3 tests). The results obtained were summarized as follows:
(1) When the learning of the single work was evaluated by the work achievement Q, it was 67.5% in the card classification test, 63.7% in the memory and operation test, and 79.5% in the both hands collaboration test, respectively. That of the combination work showed 70.0%, which was close to the mean value of the single work in comparison.
(2) When the workload of the single work was evaluated by the total workload W, it was 0.9 in the card classification test, 1.0 in the memory and operation test, and 1.4 in the both hands collaboration test, respectively. The combination work test showed 0.9, which indicated the lower workload than that of the single work.
(3) Referring to the work achievement Q related to the total workload W, a regressive equation was obtained to indicate the total workload index.
(4) The total workload index is considered useful as basic data in the production activity of every cell manufacturing firm.
