The use of computers to coordinate production in an optimal fashion has been variously proposed for socialist economies. The Polish economist Oskar Lange argued that the computer is more efficient than the market process at solving the multitude of simultaneous equations required for allocating economic inputs efficiently (either in terms of physical quantities or monetary prices).
The 1970 Chilean computer-controlled planned economy Project Cybersyn was pioneered by Salvador Allende's socialist government in an attempt to move towards decentralised economic planning with the experimental viable system model of computed organisational structure of autonomous operative units though an algedonic feedback setting and bottom-up Cyberfolk component.
Economist Pat Devine has created a model of decentralized economic planning called "negotiated coordination", which is based upon social ownership of the means of production by those affected by the use of the assets involved, with the allocation of consumer and capital goods
made through a partipatory form of decision-making plan by those at the most localised level of production.
The planning structure of a decentralized planned economy is generally based on a consumers council and producer council (or jointly, a distributive cooperative), which is sometimes called a consumers' cooperative. Producers and consumers, or their representatives, negotiate the quality and quantity of what is to be produced. This structure is central to participatory economics, guild socialism and economic theories related to anarchism.
