Re: Just in Time levelling

Thanks,

I do appreciate the replies.

Yes, we do need to do this.

The situation is a woodworking factory. The processes are typically cut the
board, edge the board, drill the board, paint the board and then put it
together. The bottleneck is in assembly, and teh saw can produce more parts
than can be assembled. So, if all the sawing happens as soon as possible, you
have to find somewhere to put all the parts that have been cut while they are
waiting to be assembled. So, it does make sense to do this. Also, it is
acceptable that all tasks become on teh critical path, that is the trade off
needed in this style of application.

I guess also on another level, you would also need to purchase all the raw
materials well in advance of needing them, cuasing more storage issues, as
well as incurring costs needlessly.

Hi,

Project is very poor at that. As you may see, many claim it is not necessary
(whereas it is a generally accepted practice in production environments);
maybe that is why the requests to develop it aren't honored.

Let's be positive: if you can fix the date at the end of the chain you can
use As Late As Possible constraints; if not you'll be condemned to make
manual adjustments, sorry:-(

Hi,

Project is doing a great job of levelling teh resources, but I cannot
figure
out how to get project to just in time various tasks. It is currently
moveing
tasks with a start as soon as possible, but it I want to delay these tasks
until they are closer to the last task in a group of tasks. Ie, task 1 is
followed by task2 which is followed on by task 4 and so on. How can I
level
so that the start of task 1 minimises time between task 1 and task 4?

Thanks,

Mike


You might consider looking at Production Scheduling software for your
situation. Project is primarily designed to do CP scheduling, something
you're not really doing. I would think, having no direct experience
with it, that production scheduling software would allow for JIT
processes, which Project doesn't do well. I Googled for production
scheduling software a week or so ago, and got lots of hits. I imagine
one of those products would serve you better.
Hope this helps in your world.
