Any tips for manufacturing/stockpile placement?

The limiting factor on my designs always seems to be resource exhaustion. Trying to figure out some ways to minimize that. While I do find instances of manufacturing with no export room of full stockpiles nearby, while assembly is waiting for resources, it does seem to be improving.

I’m pondering the impact of manufacturing everything possible, thus leaving the load on the importers for only those things we can’t produce. But where to space everything to optimize delivery, given the limitations of the game’s distribution algorithms.

Your thoughts?
