Utilizing smart manufacturing information in a job shop to support job selection and processing speed decisions

Creator:: Houck, Christopher
Abstract:: Creating schedules for the job shop manufacturing system is an extremely difficult task. Although researchers have devoted a lot of attention to generating optimal solutions, these solutions are static, thus they do not update as random events occur that disrupt the system. As smart manufacturing has grown, researchers have been...
