The Cybersyn project ("cybernetic synergy") was a Chilean attempt during the government of Salvador Allende (1970–1973) to control the centrally planned economy in real time using computers. It consisted of a teleprinter network that linked factories to a central computer in Santiago.
Technical implementation and design
Data processing: Each day, seven key figures (e.g. material consumption, production) were transmitted from the factories to an IBM System/360-50 mainframe, which calculated short-term forecasts.
Control: The system used four levels (company, branch, sector, total) based on the algedonic loop. When problems arose, the system escalated them to the next higher level.
Software: The software developed under the name "Cyberstride" was based on the "Viable System Model" and Bayesian filters. After the project ended, it was further developed commercially as "Coordinator".
Operations room: The futuristic operations room was designed by Gui Bonsiepe. It featured seven fiberglass chairs arranged around a central console with screens displaying real-time data. Only a mock-up was ever completed.
Historical context and end
Costs: Total costs were estimated at around $150,000 (as of 1973).
Military coup: After the overthrow of Allende on 11 September 1973, the control center was destroyed by the military junta under Augusto Pinochet.
Practical use and legacy
Logistical application: During a strike by haulage contractors in 1972, the teleprinter network helped the government coordinate food supplies using 200 government-loyal trucks.
Significance: Although the system was primarily intended as an instrument of planned economy, it is today sometimes referred to as a "socialist internet" or an early form of groupware due to its communication patterns.
