(.): The tensor method of dual networks was developed to calculate changes of processes in largescale systems caused by changes in the structure of links. Dual networks are constructed as dual graphs, and have an invariant of structural transformations. The dual invariant has fundamental character that turns up in the form of the law of preservation of a stream of energy. The invariant provides methods to calculate chains and network models of largescale systems of variable structure, including network models of economic systems. This paper describes the method and its applications for simulation of a product flow network and a dual network of cash flows.
