Ok, I am kind of new to PI but have been running a P3 chain for a month or so now. I noticed today as I was moving a load of 30,000 Heavymetals from one location to another to run the P1 reaction to Toxic Metals on I transported all 30K down to the planet but the interactions used up 100% of the raw Heavy Metals when there should have been a little left over. Let me exaplin:

This planet has 8 basic production facilities making Toxic metals that all feed from the spaceport so when I dropped the 30K of mats there, 8 basic processors SHOULD have sonsumed 24K of Mats and all 8 processors be shurning away leaving 6 K of mats behind. (MY math says that 8 processors x 3000 units per run each = 24K raw units).

However... not all of my processors were going as 2 of them didnt have full input resources.... so it would APPEAR That the input is actually GREATER than the stated 3000 units.

So am I missing something in PI production I didnt realize or is somethign broken?

Factories will queue up enough materials for the current job, start this job (materials are now in use and gone) and enough materials for the next job.

So a basic factory with no current job and no materials in it's queue will consume 6,000 P0.. 3,000 P3 to start the first job, and 3,000 P0 for the next job in its queue.

To summarize, you dropped off 30,000 P0 resources to a location that has 8 basic industrial facilities and no materials were left in storage?

This seems like it would be the case since if all 8 basic facilities were empty then they would take 8x6000 = 48,000 units to fill both the production needs + storage capacity at the basic industry facilities. If it (the routing you set up) prioritized some factories over others, the initial input amount + the buffer amount could have gone to some factories before it went to other factories, leaving some unable to start production.

Now if you started with 8 factories, dumped 48,000 into the pipe and everything wasn't full and running I'd say you might have a case. Does this explain your scenario?

Looks like I'm too slow today :)

Yes this makes perfect sense, thanks for the replies! I didnt realize that it consumed AND queued for the next batch at the same time. And no I dont have eny kind of priority built, the factories are all mostly a hub and spoke topology so it would make sense that some started a production run and queued up materials before another factory had grabbed enough material to start the first run.

Again Thanks for the quick replies! You mention a priority system, not sure how that would affect how I have things set up but how would you prioritize one processing facility over another to recieve materials?

Yeah this is a real PITA. The factories do not work together well.

As said above each factory does not just take the 3000 units it needs for the active run but also an additional 3000 to store in que for the next run. Each factory will take enough mats for 2 cycles. They will then refill the storage que each cycle as long as there is mats available.

You would expect all the factories to start running and whats lefts to go into the storage que of the first few factories, but this is not how it works. The factories with the shortest links to the launchpad will get fist dibs on the mats. But even this is inconsistent.

You probably ended up with 4-5 factories running with the remainder of the mats divided up between the storage que's right? Had you dropped 48k P0 all 8 factories would have started and all 8 would have full storage ques for the next cycle, still leaving nothing in the launchpad. Anything less than 42k P0 would likely result in at least the factory furthest from the launchpad to not get enough to start running.

Beware that there is no defined order for events to occur, i.e. you can't assume that event 'A' always happens before event 'B'. This can lead to lost materials and idle processors if you route direct.

If you make sure that every route either starts or ends on some sort of storage, then this problem is avoided.

Example: Processor 'A' feeding processor 'B' directly, both are 30 minutes.
* Good: Processor 'B' finishes first, so it starts another cycle by emptying its input queue. Processor 'A' then finishes and refills processor 'B' input queue.
* Bad: Processor 'A' finishes first, but processor 'B' input queue is already full, so materials are lost.

It is also possible to have a situation where a processor's input queue never fills, which can lead to the processor sometimes being idle. This is time inefficient, but at least one doesn't lose anything.
