Work center scheduling and shop load

Yahoo Archive

In v6, there is a field in the Job Operation screen called Machines.
Set that to 2 if you always want to schedule it on 2 machines.

HTH,

you want the load of that OP scheduled to be split across
multiple 'drill-#'s, set the operation scheduling blocks to indicate
how many (max) 'drill-#'s you want this OP parallel (start to start)

We have an operation that goes to a work center that has 4 machines in it. When you schedule that operation, it puts the load all on one machine.

If we decide to run 2 machines for that operation, how do you set up the job so that the load is on the work center is doubled and the job would actually finish sooner?

How can you do this on the job AND if we want to permanently use 2 machines, how do we setup our master files to reflect this?

Thanks,


Jasper

If you're on v6 - no idea.

If you're on v8 here is an example:

You have a resource group called 'drill press' with 20 identically capable & defined 'drill-1, drill-2, drill-3,... drill-20' resources set up under it.

Your method OP simply call to use resource GROUP 'drill press'. If you want the load of that OP scheduled to be split across multiple 'drill-#'s, set the operation scheduling blocks to indicate how many (max) 'drill-#'s you want this OP parallel (start to start) split scheduled across.

If you never want to consume more than 2 (perhaps because it isn't practical to do 20 simultaneous drill setups or effectively block any other job OPs from having capacity to run in parallel to the current job) - set scheduling blocks to 2.

Theoretically I think you can do this at the individual job op detail level as well. I seem to recall som issue with the scheduling blocks field being disabled (read only if the job details were generated from a method) - or perhaps even hidden - in job entry. (Nothing that couldn't be cured with some .NET customization.)

We don't do this - but I recall testing it on one of the 305's when piloting and it produced some odd results in regard to perceived capacity & resulting cost. Those problems observed could have been bugs since fixed.

I suggest you model it in your train db and test it thoroughly 1st.

Other systems I've used handle this much more efficiently (re long term method maintenance and job management)... You could simply set an OP in a method (or in a job's details) to either process "S"erially or in "P"arallel if multiple qualified resources are available.

That simplification also applies to the whole nutty (only an OOP programmer would love it) resource group/resource paradigm. Older systems simply allowed you to create a workcenter (resource) & indicate how many machines or people it had available to schedule into their capacity.

Good luck!

We have an operation that goes to a work center that has 4 machines in it. When you schedule that operation, it puts the load all on one machine.

If we decide to run 2 machines for that operation, how do you set up the job so that the load is on the work center is doubled and the job would actually finish sooner?

How can you do this on the job AND if we want to permanently use 2 machines, how do we setup our master files to reflect this?

Thanks,

Jasper
