I'm interested in this. So far, the best resources I found are:

- "Red Plenty" by Francis Spufford, a mix of fiction and non-fiction about planning experience in the USSR. It includes a rich bibliography and references to papers published over the past 70 years around this issue.

- There are few papers by Chinese economists, most notably this one: https://boingboing.net/2017/09/14/platform-socialism.html (you have to mess around with Sci-Hub mirrors to get a free copy).

- There are few papers and books by Michael Ellman, e.g.: https://www.amazon.com/Planning-Problems-USSR-Contribution-M...

- I also have a few primers on linear programming in my to-do list, e.g.: https://www.amazon.com/gp/product/0486654915/

- Somewhat tangential, but "the greatest American capitalist" ripping into EMH is a fun read too: https://www8.gsb.columbia.edu/articles/columbia-business/sup...

None of these really talk about the software still, but I would imagine a combination of:

- existing supply-chain systems already in place at Amazon, Walmart, etc.,

- something along the lines of non-monetary Kickstarter to gauge popularity of ideas from the ground up, and encourage innovation

- strong democratic institutions

- still allow free market at low levels, like individual entrepreneurs that don't employ anybody (once you employ someone, it must be a co-op).

Dunno, these are just random ideas in my head. :)
