However, it has increased the mean lateness from - 3625 minutes to 4.5 minutes. Also the number of late jobs has increased from 4 to 6. C. Slack Time Remaining (STR) Rule Slack time for a job is defined as the due date of the job minus its processing time. Sequencing the jobs in such a way that the jobs with the least slack time are picked up first for processing, followed by the one with the next smallest slack time and so on is called the slack time remaining (STR) rule EXAMPLE 5.3-4 The information regarding jobs to be scheduled through one machine is given below.
