We consider the problems of complex structure teplotehnologicheskih complexes manufactures pulp and paper industry. Proposed and carried out structural analysis teplotehnologicheskih paper production complex in pulp and paper mills. Use graph theory and matrix analysis. Apply the authors developed a universal application in C # for the analysis of complex structured system of industrial circuits, power complexes. We obtained the results of the work program for the production of paper teplotehnologicheskoj scheme. Revealed all the circuits with the scheme. Identified torn flows for sequential calculation scheme without iterations. structural analysis program can be recommended for use and other industrial multi-loop circuit industry.

Keywords: structural analysis, feedback, teplotehnologicheskih scheme, industry, software, iteration
