A process is scheduled based on one or more tasks identified as control tasks from a set of tasks comprising part of a job. A desired work-in-progress load time level is set for each of the identified control tasks, and a time load on each of the identified control tasks is determined for each new job, each new job comprising one or more tasks. New jobs are released based on the desired work-in-progress load time level for one or more control tasks to approximately maintain the set desired work-in-progress load time level.
