Abstract—We believe that, at present, researchers cannot develop an effective method of support due to insufficient theoretical knowledge about structural identification. The work contains a new approach to the development of the combined support method. This approach, in particular, includes the comprehensive application of the system approach, the principle of considering structural identification and the problem of creating a combined support method as system objects, and the comprehensive application of an interdisciplinary approach. Taken together, the new results formulation of the problem of creating a combined support method.
