Snytyuk V. Methods of a diminution of determinacy on the initial stages of systems with variable structure design

The dissertation is devoted to problems of a diminution of indeterminacy on the initial stages of system design. In a thesis the new approach to system design with a variable structure is developed. In its basis the process of forming of a system model lays. It is determined, that the forming of levels of a system model makes the definition of a measure of existence of a design solution possible. The problems of the purposes formulating in conditions of indeterminacy of an information are classified. The methods of the determining of a measure of a coherence of values of parameters indicated in a requirement specification with an expert evaluation of their deriving are offered. The basic outcomes of work can be used at a decision making about a possibility of a realization of the projects of complicated engineering systems.
