Abstract
This study is considered on a theory that the schedule for large-sized job manufacturing products is reduced. The result is revealed that (1) the minimization of the assembly schedule is that the relationship between the assembly schedule of each operation per operator and the number of operators is ordered of the large size, (2) from the viewpoint of the schedule synthesized the assembly schedule, the minimization of the machining schedule when independent machining in all jobs is possible is that the machining schedule of each job is ordered of the small size.
