Abstract
The paper describes a new approach to presenting of the information about the control system states and processing of this information for the control decision-making. The ranks between distances of system states but not these distances are important information for implementation of procedures to identifying states and optimization of the system in this approach. The concept of rank configurations and special binary codes for their encoding are introduced. Different models of ranked configurations for defining the characteristics of these codes are presented. The interval model of ranked configurations to determine the completeness of such codes and a method and algorithm for evaluation of its adequacy are designed. The results of the algorithm performance are presented.
