Abstract
In the actual production site, a plurality of worker who operates the machine exists, depending on the skill level by the workers for each machine, working time is different even if the same work on the same machine. Therefore, it is proposed to account for differences in working time by the worker is Scheduling Problem with Worker Allocation (SPWA). In this paper, in order to approach the more realistic model by dividing into several class workers, to determine the skill level for each machine for each class workers, we propose a new model that introduced the concept of class-type skill, demonstrate the effectiveness the computational result by GA algorithm.
