CyberSYn was actually a decentralised network, ie factories could talk to each other, councils to each other, and state and such. CyberSyn was basically the internet before the internet, they used radio signals instead of fiber optic cables to communicate with simple computers. Today a rebuild of cybersyn or equivalent would require a shut down of the entire nations electricity supply, assuming the factories dont have their own. CyberSyn wasn't even known about by pinochet until they discovered it, they destroyed it because they wanted to restore capitalism.
The planning for the overall economy ie very large infrastucture project, or a directive to do something ie increase supply or service of this was centrally done, but much of it was handled indirectly, workers and their councils had a huge amount of control over how this actually worked. CyberSyn was based off the idea of the state and workers being partners working together to better the country and its people, and mutual trust.
