Global Finite Scheduling

I am curious of any information you can relay to me regarding global
scheduling. We have just went to global forwarding and I am
wondering if you run the global scheduling then mrp and what issues
you have had with the global schedule or any help you can offer.

What version are you running, Nam?



I am considering this as well. Unfortunately, at this point, we only use
the job scheduling function to facilitate the calculations related to
time-phase material requirements and purchase suggestions. We are not using
Scheduling to plan/monitor/adjust production capacity for two basic reasons.
Firstly and primarily, many of our jobs are not sufficiently planned
operationally to be conducive to scheduling. Secondly, nobody seems
interested in using the scheduling boards. I'm thinking that perhaps we
don't have anything to lose by running GFS, but I've been cautioned in the
past about doing this. I was advised just to use Job Scheduling and then
adjust the production schedule using the scheduling boards, but that brings
me right back to my previous statement. Anyway, I would be particularly
interested in hearing about pitfalls that others have encountered with GFS.

Hi Everyone,

I am planning to use Global Finite Scheduling to help avoiding over
capacity.

Anyone has used this Global Finite Scheduling? any impact or must be
aware of. What is the best procedures to implement this GFS?

Would like to have yout input.

Thanks,

Nam

Morning,

There are many different levels of functionality in Global Finite
Scheduling.

1) The Basic Level - No Finite capacities. This will run just based
on due dates and try to backward and forward schedule as the best it
can.
2) Limited Finite capacity - Some workcenters will have finite
capacity. So it will try and schedule the earliest due dates first
and then take into account the finite capacities.
3) Full finite capacity - all workcenters have finite capacity.

Into the mix goes priority codes which basically gives a capacity
where possible to those jobs with a higher priority code.

In terms of trying to implement global finite scheduling you can
split it into two categories but supplement each other.

Structures

1. Ensure Workcenters and Operations are accurate
a) Number of Machines
b) Hours per machine
c) Finite or not.
2. Calendars are accurate.

Processes

1. Ensure that job bookings are timely.
2. Ensure initial schedule is reasonable
3. Ensure that there is a scheduling process for prior and post
global rescheduling.
4. Ensure that there is a process for updating the shop floor with
the new schedule.

In terms of implementation;

Do a lot of testing, so if you decide that you will reschedule every
monday, take a copy of the database every monday and do a reschedule
on that etc.

I would recommend that you do this a couple times with your current
configuration to assess how accurate it is.

Remember that the global rescheduling is good but it is not a self
contained process , the scheduler will need to manage it so training
and additional will be requried.

The other side benefit, if you have a large number of jobs and
bookings the rescheduling routine seems to clear some things up and
the reports tend to be more accurate. Generally, if possible, keep
it as simple as possible. Don't try and tie everything down. Use the
testing to identify the exact issues, is it the job configuration,
workcenter configurations etc.

I hope this helps.

Hi Scott,

We are running version 6.1. We are looking for a better way to
schedule the jobs for production plan. We are currently schedule the
jobs according to the due date but we running into over capacity

Thanks,

Keep in mind that in 6.1 Vantage schedules into the past on operations
that have already started. 8.0 is supposed to change this.

We use Global Finite Scheduling and have switched from finite capacities
to infinite. The problem is that infinite would be great for the shop,
and finite is great for sales (to quote accurate lead times). We still
aren't sure which we like more.

Brychan how often do you run Global Finite Scheduling and do you use the
MRP module ?
