The DDATE rule sequences the jobs based on their due dates, starting with the earliest due date. The mean tardiness for all jobs can be calculated by subtracting their due date from their completion date and taking the average. By sequencing the jobs according to the DDATE rule, the jobs with earlier due dates will be completed earlier, reducing their tardiness. The calculation result is a mean tardiness of 5.4 days.
