Additionally, the import of Master Production Schedules
to individual machine Job Queue facilitates dynamic production scheduling and real-time Job completion tracking.
However, this safety stock may inflate the master production schedule
by overstating requirements for all resources and result in high inventory carrying cost.
The use case diagram for setting the master production schedule
