Join Chris Croft for an in-depth discussion in this video Reducing lead time using a pull approach to reduce buffers, part of Process Improvement Foundations.
- We've already seen the queues are inevitable…unless you have spare capacity which is expensive.…And if you have lots of different components…moving through a factory with lots of machines…maybe each component takes a different route,…spends different amounts of time…at each machine that it visits…and you're bound to have queues in some places.…And one approach to handling all these…will be to have an incredibly clever computer…which knows everything and it would work out the best way…to push everything through the factory or the office.…But even now with all our computing power…this problem hasn't really been solved mathematically.…
And of course, as soon as something changes,…the whole thing has to be recalculated.…So the best approach is probably to simplify the problem…in one of two ways.…One is as we've seen earlier,…to focus only on the bottleneck of your system,…but the other, is to use pull systems…and that's what this section is about.…What is a pull system and how can you use one?…Well the basic idea is that you don't produce any work…
