Optimal Economic Work Assignment in Robot Labor

摘要

The highest balancing efficiency in robot work is attained by the minimum number of robots. When the minimum number of robots is not attained by the cycle time, it can be attained by increasing the cycle time. But increasing the cycle time leads to a rise in cost because the robot functions increase. This study, therefore, searches for a work configuration where the number of robots times cost is at a minimum. As most practical factories engage in manufacturing multiple products, it is searched from the viewpoint of all products manufactured in robot line of a factory. As a result, we propose how to obtain minimum cost using cycle time and the number of robots ,or namely, the optimal economic assignment. Finally, the procedure for creasing the optimal economic work assignment is presented.
