Abstract


The subject of the research in this article is the creation of a mathematical model of the process of technical operation (PTO) of a military aircraft in the system of information support for the operation of an aircraft. The aircraft is a complex technical system that includes many systems, subsystems, and elements for reliable and error-free functioning, which require constant monitoring of its technical condition to determine the possibility of its intended use. It is proposed to promote PTO in the system of information support for the operation of aircraft operating in real time and to create a mathematical model of the process. We will construct a graph of states and transitions using the transition matrix to describe the PTO of a military aircraft. The purpose of this study is to create a mathematical model of the PTO of a military aircraft in a system of information support for the operation of the aircraft operating on a real time scale. The task: to determine the role and advantage of using the mathematical model of the PTE of a military aircraft in the information support system for the operation of a CMMS-type aircraft operating in real time for its use in forecasting and managing the effectiveness of the PTE. The scientific and practical novelty of the obtained results is as follows: the advantages of the PTE mathematical model of a military aircraft in the CMMS-type aircraft operation information support system, which works in real time before the PTO model by resource and the model when decisions are made at the moment, have been determined state changes. The conclusion of this study is that the use of the proposed PTO model will allow us to evaluate complex reliability indicators in real time, that is, continuously. The considered PTO model of a military aircraft considers all the features of military aircraft operation at the current stage. This allows us to assume the possibility of its use for the entire aircraft fleet of the Air Force Base of the Armed Forces of Ukraine.
