# What is EDD rule?

**EDD**) or

**EDD**

**rule**that sequences the jobs in a queue according to their (operation or job) due dates.

Also, what is the SPT rule?

shortest processing time (**SPT**) A priority sequencing **rule** that specifies that the job requiring the shortest processing time is the next job to be processed. The difference between the due date and today's date must be in the same time units as the total shop time remaining.

Similarly, what are the priority rules? **Priority rules** provide guidelines for the sequence in which jobs should be worked. The **rules** generally involve the assumption that job setup cost and time is independent of. processing times. In using this **rules**, job processing times and due dates are important pieces. of information.

Also to know is, what is the average past due in days using the EDD rule?

**EDD** (Earliest **Due** Date). **EDD** sequencing **rule** is that “jobs are processed according to the **due** date, earliest **due** date first.” completed before the **due** date under **EDD rule**. The **average** flow time is 13.98 **days** and the **average** lateness is -1.22 **days**.

How is tardiness calculated in sequencing?

A job's **lateness** is **calculated** by subtracting the due date from the operating time. A negative number means the job is finished early, zero is on time, and a positive number results in a late job. The number of late jobs was also determined through the analysis. The lower the number of late jobs, the better.
