Electric models of large-scale systems and their analogy with thermodynamic systems

The paper deals with electric models applied to investigating sophisticated systems, such as transport, economics and neuron ones. Interest in these systems can be explained by the fact that they are characterized by parallel (collective) means of calculating sophisticated processes, which are carried out without any calculation program, but under the influence of sophisticated inner information processes. Electric models can also be looked upon as original structures for neuron-like systems. The paper emphasizes comparison between suggested electric models, on one hand, and mechanical and thermal models, on the other. It has been shown that entropy phenomena, typical for the latter, can be closely compared to those in electric models, which are distinguished by pure electrical values. Also, it has been shown that irreversible processes of energy dissipation. e.g. entropy processes in mechanical models, correspond to processes of energy concentration, energy transfer and/or energy exchange in electric models. This enables new light to be shed on processes in electric circuits, especially those concerned with structural improvements of electric circuitry, their self-organization meaning a neg-entropic information character for these processes. Models of two economic tasks are considered, wherein the calculation process is characterized under the influence of those processes. Assumption of the importance of reactive elements, such as carriers of neg-entropy in an electric circuit, is made.
