The informal modeling of input-preprocessing subsystems for scientific research

The subsystem of input and preprocessing of the information (SIPI) as the constituent part of an automated system for scientific research (ASSR) is considered. With the purposes of systematization of methods and construction tools of the given subsystem depending on time and precision characteristics the informal model of its operation was developed. The subject knowledge of the researched object of modeling, methodology of the structured analysis and design technique (SADT), and also international standards were put at the heart of formalization.
