Mafouta T. Models of access control in computer networks of corporation information systems

Object of research - process of transfer of the information in a connecting part of corporate information system. Subject of research - mathematical models of managerial processes by access to a connecting part of a corporate information network. The purpose of research - increase of efficiency of data transmission in a connecting part of a corporate information network in view of necessity of prevention of possible(probable) his underloading or overloading occurences and taking in account of stage-by-stage development of the corporate organization. Theoretical value of results of research - the new mathematical model of managerial process by access to a connecting part of corporate information system in a multi time sharing mode which is based on event-binary approach to the description of managerial process by access is received; the mathematical model of managerial process by access to a connecting part of corporate information system in a mono time sharing mode which takes into account influence of full, cluster and selective mechanisms of management of repeated transfer of the deformed block of the data is advanced; for the first time the method of optimization of non-standard parameters of a connecting link of corporate information system which uses working loading as criterion function is developed and takes into account restrictions on exploitation-economic losses and on deterioration of functioning of a connecting link. Practical value of results of research - more effective discipline of priority management by the access, based on a multilevel principle is offered; the algorithm of processing of the binary data for calculation of probability and time characteristics of managerial process by access to a connecting part of corporate information system in a multi time sharing mode is developed; the algorithm of definition of a maximum of working loading of a connecting link of corporate information system is developed; the technique of realization of strategy stage-by-stage increases of productivity of a connecting link of corporate information system is developed.
