Identification of effective states in networks of industrial elements. I

A model is described which represents the functioning of inter-linked «economic elements» the prices of whose products do not by themselves make the supply and demand agree. Sufficient conditions are proposed which make it possible to increase or decrease the output with only qualitative data available on the state of current elements. A class of effective network states is found and conditions are specified with which states of this kind are identified. The paper consits of three parts. The first introduces notions of network quasi-equilibrium in which the states of elements are in a cerfain sense in agreement.
