Theoretical Substantiation of Management of Functioning of Technical and Transport Systems on the Basis of Methods of the System Theory of Information

Abstract

In the work from the theoretical point of view the management of functioning of transport and operation of technical systems on the basis of a method of the system theory of information is substantiated. The state vector and matrix on the basis of diagnostic information and sensitivity of influence of diagnostic parameters on a condition of transport or technical systems are offered. The properties of sensitivity (sensitivity) are reflected on the basis of classical and generalized information formulas of A. Kharkevich, K. Shannon, R. Hartley. The coefficients of quantum (emergence) of information according to the expressions of Shannon-Kharkevich and Hartley are used, the level of complexity of the changed states of the control system is taken into account. The scheme of connections of classical and generalized formulas which reflect functions of density of the diagnostic information on a condition of technical and transport systems is constructed. A universal numerical method and tools for it have been developed, which allows to perform information calculations on the basis of diagnostic data of the state of the studied objects. Numerical calculation refers to the sensitivity of the state (sensitivity factor) of technical and transport systems. The level of system organization of transport and technical systems and their management as active objects is considered. It is noted that the principle of correspondence is fulfilled, which is mandatory for a more general information theory. The system modification is implemented using the Hartley formula, and the modification in the classical case is the Kharkevich formula. It is determined that the semantic information model allows for small samples and comparison of partial criteria to well substantiate the interpretations of object state recognition, developed by the vectors of their classes. It is revealed that the semantic information model combines the advantages of meaningful and statistical models created for the implementation of the automated system of cognitive analysis of transport and technical systems. The behavior of systems is revealed when they are completely deterministic and completely random, which is important in predicting their state.

Creation of theoretical bases of tribotechnologies of running-in and restoration as means of effective increase of operational wear resistance of motor transport and mobile agricultural machinery

“…According to the results of studies [15,[17][18][19][20] related to the introduction of tribotechnologies of runningin and recovery, the best effect can be achieved with an average degree (up to 50%) of wear and tear of engines and transmissions of motor vehicles and mobile agricultural machinery. In practice, engines whose oils are treated with a tribocomposition of additives before running-in, or in the process of running-in have 3 times more service life and no breakdowns, in contrast to untreated motor oil [1,[21][22][23].…”
