Tensor method dual networks enable you to create network models of processes and structures of the system. Network models provide the calculation process when the structure is changes. For example, calculating changes in disabling or destroying elements of the technical system. It is necessary to predict safety, in particular, of refining facilities. The essence of network models is that the flows quantities in the system are the components in the space structure open and closed paths basis. When the structure changing the new values flow quantities calculates like coordinate transformation, caused by change of paths. Such tensor transformation provides discovered by author dual networks structure change invariant. The physical meaning of this invariant is a constancy of power in two dual networks when the structure is changes. This is a manifestation of the law of conservation of energy flow.
