The purpose of this work is to assess the quality of functioning intelligent systems. Tasks to be solved: synthesis of an intelligent system based on unified modules, system quality assessment, system reconfiguration at a quality decrease. The research method is system analysis. A new flexible programmable architecture of intelligent systems has been developed. The flexible architecture of an intelligent system allows you to change the mutual relationships between subsystems, components and modules. The intelligent system is implemented on the basis of the unified modules that contain programmable switches. Switches are connected to the system inputs and outputs and are networked to transmit information.
