Abstract. On the example of synthesis of structure of two-level distributed system of collection and pro-cessing of information on technical condition of space vehicles in the course of their life cycle, a state-ment is given of the problem of formation of the information system target state. An approach to imple-mentation of the concept of functional-structural synthesis of complex systems based on solution of mul-ti-criteria discrete programming problem is used. Composition and dimensions of generalized vectors of structural parameters of the system and its elements are specified. Expressions for estimating the prob-lem dimensionality are presented. It is concluded that a special technique of reduced iteration of infor-mation system variants is necessary to be applied.

Keywords: information acquisition and processing system, spacecraft, functional-structural synthesis, multicriterial discrete programming.
