The analysis of features planning for distribution an information resource is carried out to ACS of a special purpose. On the basis of the carried out analysis the task of development the model based on the relevant structure of the schedule system considering restrictions specific for considered by ACS is formulated. Two options of mathematical distribution model of information blocks on the distributed knots of the ACS basic information and telecommunication network for a special purpose are developed. ACS Special Features recorded in the developed model by introducing a utility function. The developed models are oriented on dynamic planning of distribution of an information resource. Dynamics of processes is discrete and depends on state change. This feature is especially urgent for execution of the transactions requiring a real time mode. It is supposed that the basic operating system has heterogeneous Hardware and software. In case of simulation of the processes happening in the appropriate information subsystems the multilayer system of processing and data storage is used. For this purpose in case of a system design or its upgrade the model of hierarchical separation of an information resource which can be considered rather independently and irrespective of interaction with external subscribers is created. Each following level of model hierarchical separation for information resource is characterized by increase in time for information access and reduction in cost to storage unit of data.</p>}, number={1}, journal={Collection "Information Technology and Security"}, author={Subach, Ihor and Chauzov, Oleksandr and Kuchuk, Nina}, year={2016}, month={Jun.}, pages={75–84} }
