Method of Forming the Requirements to Information Support Characteristics of Control Systems of Unmanned Aircraft Transport Systems

Abstract

Purpose or research. The aim of the study is to develop and describe a method of forming the requirements to information support characteristics of control systems (CS) of unmanned aircraft transport systems (UATS) to ensure the safety of flights.Methods. The proposed method of forming the requirements to information support characteristics of UATS CS is based on the methods of system analysis, cognitive approach, and methods of multi-criteria decision analysis.Results. The paper considers and describes main tasks solved at the stage of concept definition, including analysis of the requirements to performance indicators, functional description, physical implementation description, and design solutions validation. Within the architectural design and analysis, a set of subsystems (the presence of which in UATS CS is required for the implementation of functions and compliance with functional requirements), and the corresponding set of modules of each subsystem have been defined. The advantages and disadvantages of various functional architectures of UATS CS subsystems have been analyzed. Based on the results of the concept formation, and architectural design and analysis, the basic and auxiliary characteristics of UATS CS information support have been generalized and presented. It is shown that in order to solve the problem of assessment of the influence of information support characteristics on the indicators of the functioning of UATS CS intellectual automation technologies it is necessary to use cognitive approach and methods of multi-criteria decision analysis. The application of the proposed method of forming of UATS CS information support characteristics is shown on the example of a real transportation problem.Conclusion. The proposed method allows forming the requirements to UATS CS information support and its characteristics, based on the purpose of the system and its functional architecture (including the composition and structure of information flows, output and transmission format, frequency of information delivery, etc.) to ensure the required adequacy, completeness and timeliness of information required for decision-making.
