Hello fellow capsuleers,

Me and my corpies are manufacturing some carriers and dreads, and it looks like we are hitting the system(s) pretty hard because the index is climbing pretty fast.

My question: Is there a way to guesstimate or calculate how many jobhours we can put in, in a particular system before we let the index climb over say 2%?

Obviously because of the size of capital parts it is a pain in the ass to spread out building over multiple systems. We have already separated parts building and hull building into two systems. We did this after we noticed that our original building system was climbing rapidly, so wel kept the hullbuidling limited to that system. This is a month ago and the index in the "hull system" doesn't seem to have dropped that much.

It's safe to say that we are pretty much the only ones manufacturing in both systems, so we are the only ones that are hitting it.

Thanks in advance.

"When you install any industrial job - manufacturing or science - you need to pay an installation cost. This installation cost is calculated per system, and is dynamic, being based on how many other people have been using that system for manufacturing over the last 28 days (measured in job-hours, not # of jobs or # of people)[...]"

"The system cost index is calculated by the number of system-job-hours, divided by total-universe-job-hours, and then square rooted for better numbers. This value (measured as a percentage, generally in the 0.01% to 5% range)[...]"

"We "use" about about 4,500-5500h/day and we seem to change the index substantiully by ourselfs.

The current system we are in started at 0,57% 2 weeks ago and today the index is 4,4%, this should suggest that the total amount of manu. hours is in the vicinity of 70,000,000 Hours/28 day period.

This number is an aproximation since lately new corps have turned up (we have put teams here for billions again) and how much they produce i cant know for sure except i can guess according to how many jobs they install.

Our strategy will propably be to spread out and see if that works and by that not putting to many good teams in the same system and hope that helps a bit.

This was just some info of what we have experienced so far and i will post my stats. as soon as i have got them together."

I couldn't find better informations about this unfortunately. Finding a dynamic total-universe-job-hours and a dynamic system-job-hours datas would help to make actual calculations. But for now, we'll have to refer to this pesky index and deal with it Sad

at least teams are gone and people will no longer hurt themselves by improving the system that way

now about finding ways to reduce the manufacturing fees for organized groups ...

IIrc there's a hidden factor that affects the SI. The number of stations within the system (with similar services?).
It acts as a damper to the rise. Never bothered to dig deeper into the relationship as I don't do fulltime manufacture.

If this is true and we manufacture in a single station system, would putting up POS' with extra arrays help?

No. It's simply the number of job hours mashed into the total job hours, mitigated by discounts for the number of stations.

Take Penirgman with like 14 stations and Chaven with 1, if both had the same SI, an additional producer in Penirgman would impact the SI less than an additional producer in Chaven. The reality is that 33 full time slots in any one-station system will have a 3% SI, 200+ full time slots in a large system will have a 4% SI. Looking around quite frequently, even an empty system with one producing POS quickly goes up to 2.5%, and only exceptionally busy systems push 5% or more.
