Job Start/Due Hour

Can someone help me understand Start/Due Hour

Op 10 and 30 use a 9hr calendar 5-14
Op 20 uses a 24hr calendar
We are backward scheduling
Op 20 has 24hrs of Move Time, the other operations do not have any Move or Queue Time.
Op 20 is ‘Start-to-Start’ with Op 10.

Backwards scheduling from Op 30, due hour of 14.00 makes sense, thats the last production hour of that calendar, goes back 2.82 based on Est Prod Hours, Op 30 needs to start at 11.18 to be complete in time.

Op 20 has no Est Prod Hours, but it does have 24hrs of Move Time. With a MoveDueHour of 11.18 and a MoveDueDate of the 16th why is it scheduling the Start Hour to be 11.82 on the 15th? This should be StartHour of 11.18 on the 15th.

This is throwing off Op 10 which starts at 11.82 on the 15th and then finishes 5.64 on the 16th, it has to sneak in some production time the following day.

Op 10 should be finishing 14.00 on the 15th and a start time of 11.18 on the 15th, Op 20 as ‘Start-to-Start’ should also start 11.18 on the 15th and 24hrs Move Time finishes 11.18 on the 16th, perfect timing for Op 30 to start at 11.18 and finish by 14.00 on the 16th.

Is there any Setup time?

3

Also, are you scheduling finite or infinite ?

4

No setup time, infinite scheduling.

5

What does the Scheduling Log say? Specifically why it chose 11.82.

6

Full schedule log for Op 20 is below, Op 30 worked/looked fine in the log, correct start time of 11.18. And i didn’t double paste into here, it ran scheduling on Op 20 twice?

It is saying that the resource is not available at 11.18. Do you have a send ahead on Op 10?

8

No, ‘Send Ahead Offset’ is 0.00.

9

Why is Op 10 starting at that time? That is probable what is driving Op 20 to that time then.

10

Here’s the entire log for all ops.

Op 10 is forward scheduling? Is that just what happens for the 1st op, i don’t think you can set forward/backward scheduling per op/resource.

Can you verify in the method that Op 10 & 20 are set to run Finish-to-Start and not Start-to-Start?

12

This is where it is going all cattywampus. There is something there that is stopping it from using 11.18. What does the resource scheduling board look like for that resource on Op 20?

The forward scheduling is because they operations are Start to Start. Since you are Backwards scheduling, it is determining the start time of Op 20 first, and then FS Op 10 to start at the same time.

13

Op 10 and Op 30 are Finish-to-Start
Op 20 is Start-to-Start, this is because the 24hr curing time i’m trying to account for here begins right away after the 1st piece comes out of Op 10. This made sense to me so that the 24hrs didn’t have to start at the end of an operation.

So i do have a few test jobs in here that i was using prior to the step i’m at now. Infinite scheduling means that shouldn’t affect anything, the job # i’m currently looking at is 293772.

Correct, Infinite scheduling should make it so that it should schedule whenever needed, but I just wanted to make sure there was no down time or anything on the schedule.

Is job 293767 have the same start time for that operation? I’m wondering what would happen if you deleted that job.

15

It does…or did until i deleted it, rescheduled 293772 and now the StartHour is correct…???

Also, looking at Resource Scheduling Board from my previous post, it was showing the jobs on Wednesday May 14th, and all the other pics i posted clearly show the StartDate as the 15th.

Now after deleted the other jobs, rescheduling the 1, the resource scheduling board shows it on Thursday May 15th (correct)…what is going on.

Not sure. Wondering if you have a setting somewhere that saw two operations on the same machine and lined them up. Or if there is actually something in the logic that does that anyways.

17

I created another 4 identical jobs on that date, they all scheduled to the exact same time, the correct time and date. Also created a 5th larger job and that too scheduled the correct time, backwards scheduling from 14.00.

Not sure i’m able to learn anything out of this but my problem appears to be solved. Thank you for the dialogue @jkane, appreciate it.
