A method of multi-nomenclature production in terms technical and economic indicators was considered. An integrated design system that is able to assess the real relationship “partmachine-transport device-device-tool” proposed, arelationship between elements an automated machine tool examined. The structure system, proposed form a mixed graph, represented by sets described nonlinear equations, d...
