We consider an approach to substantiating the utility function to obtain initial estimates for the quality indicators of complex technical systems (CTS) in the form of a formalized information model taking into account the consistency of expert estimates. As an object of СTS research, there is a model for a truck with a trailer as part of multifunctional complexes with unmanned aerial vehicles (UAV). A model and algorithmization of the process of forming an information-analytical system with the results obtained for selected indicators for assessing the technical level of a truck with a trailer are presented.
