LOSKUTOV, A.A. BYANKIN, D.B. SYEMYENYUK, V.A. KLYKOV The article deals with the development of methods for constructing a mathematical model of onboard electronic equipment of objects of rocket and space technology, taking into account the multidimensional nature of this equipment. The problem of developing a method of synthesis of a mathematical model based on a polymodel approach is formulated. The method of synthesis of mathematical model of functioning of the onboard radio-electronic equipment of objects of rocket and space equipment on the basis of the polymodel approach with the entered relation of a strict order between models is presented. As a mathematical apparatus used to formalize the process of functioning of the simulated system at the senior level, a finite state machine is selected, at the lower level – the mathematical apparatus of Petri nets. For the formalized transition between mathematical models at different levels of detail and abstraction, an approach based on the construction of a fragmentary syntactically correct parallel graph-scheme of the algorithm is used. An example of a formalized transition from the elements of the senior level model to the elements of the mathematical model of the Junior level is given. Keywords: Mathematical model, dynamic system, onboard electronic equipment, parallel graph-scheme of the algorithm, Petri net, finite state machine.
