Hey,
I am in need of manufacturing/scheduling help.
This site runs lots and lots of small jobs, or at least jobs that take a short time to run and finish—many running 30 minutes to an hour long, so scheduling is a pain.
The jobs do involve setup on fixtures, so they want to schedule jobs with the same setups together on the same resource when possible.
I created some setup groups like this:
Setup Group Description
110_MM 110 MM Cut
130_MM 130 MM Cut
220_MM 220 MM Cut
And set them on the (only) operation on the parts’ MOMs for these parts:
17166890
17152893
17168113
Then I set up the operation’s resources for finite capacity. The operation is a pack, with five assembly line resources connected to the resource group.
I was hoping the scheduler would assign the job suggestions to separate resources, or at least assign them sequentially, but here’s what I got:
Line 1 Line 2 Line 3 Line 4 Line 5
Part Num Time Part Num Time Part Num Time Part Num Time Part Num Time
17168113 20190707 18:30 - 19:11 17168113 20190707 17:58 - 18:39 17168113 20190707 18:39 - 19:20 17168113 20190707 18:39 - 19:20 17168113 20190707 18:16 - 18:57

17152893 20190707 23:01 - 00:00 (gap)
17168113 20190707 - 23:19 - 00:00
This table’s probably a jumbled mess (copy and paste to Excel would straighten it), but the short story is it didn’t group all similar jobs together.
The only setting I see on the setup group is a “Scheduling Precedence.” I don’t think I need to set a precedence of one setup group over another, but would just like similar jobs to run together.
Anyone had success using setup groups to do something like this?
Thanks,
Joe
