An approach to assessing complex technical systems at an early stage of development

An approach to assessing complex technical systems at an early stage of their development is considered. Complexes with multifunctional dual-use unmanned aerial vehicles are being investigated as complex technical systems. The novelty of the work lies in the integration of the assessment by structuring the methods and stochastic models of the analysis of complex technical systems in the technological computerized environment of the developer, choosing a decision-making strategy at the stages of preliminary design, including the method of expert assessments. Using the example of unmanned aerial vehicles (UAVs), the technology of choosing a rational version of complex technical systems from among the alternatives of the formed model range using an information and analytical system (IAS) is shown. The IAS implements a procedure for multi-criteria assessment of complex technical systems based on the methods of expert assessments. The primary results of a comprehensive assessment of reconnaissance-strike and strike complexes of multifunctional UAVs weighing 0.3-2 tons have been obtained.
