Are there any ERP(or otherwise) software packages that incorporate I/O LP planning interfaces? I was curious about the feasibility of using it to plan production in a co-op.
Maybe https://ogasdemo.ru/ could be useful for this? Also input-output sucks for actual planning since it implies a square system whereas real production requires rectangular matrices.
I now remember ogasdemo uses input-output, so unfortunately its usefulness is likely to be limited..
@thardin I thought even if you have a rectangular matrix your still doing I/O as you are computing intermediate goods with vector matrix operations, is the general case called linear production theory?
Also if you are doing just intrafirm planning for a co-op are would the tables be large/dense enough that square matrices are a problem?
@madredalchemist I/O almost always means Leontief style planning. The word you're looking for is supply-use. There is planning theory especially in the Russosphere that is effectively useless for operational planning because it uses I/O. That is it assumes exactly one production method per product, no side products aka no joint production, and so on. Having talked to Grigori Kopanev and looking at the ogasdemo code it is apparent that it can only do I/O aka square systems.
There are multiple free software ERP systems, but I have no idea whether any of them are suitable. I haven't found the motivation to set any of them up. A good project would be to try all of them and write a report about it.
The size/density isn't the problem, it's the inflexibility of I/O that is the problem. This becomes immediately obvious if you sit down and actually attempt to use I/O for a toy economy like Workers & Resources, especially electricity production.
