The relevance of the study is due to the fact that the support of management information processes of distance and mobile education is associated with the problem of efective distribution of system resources used in the transmission and processing of educational information. Methods and models of pre-resource planning should be aimed at more eficient use of infocommunication data transmission environment with low bandwidth, as well as to solve the problem of a limited number of simultaneous users (sessions) of the educational process. The aim of the study: is a comprehensive analysis and development of methods of resource management in the organization and operation of distance and mobile education systems. Scientific novelty of research : formalization of information management processes in the system of distance and mobile education, taking into account the resource constraints of the educational system, the requirements of efective management. The authors conducted a study of existing information systems that control distance and mobile education. We proposed an improved integrated approach to the formation of requirements and automation of modern systems of distance and mobile education.

The processes of Informatization of society could not but afect the development
of educational systems. The use of modern network information technologies in the
educational process has greatly contributed to making learning as accessible, open and
popular as possible by the wider society. At the same time, training, initially associated
with the accumulation, transformation and replication of knowledge, that is, information,
the very content of its goals and objectives contributes to the development of new
services, the expansion of management, communication and information fields [
In the conditions of rapid development of methods and forms of training, the key
point of application of modern information and communication technologies, mechanisms
and controls should be the direction of automation of information processes of remote
network training [
On the other hand, we note that the support of management information processes of distance and mobile education is associated with the problem of efective distribution of system resources used in the transmission and processing of educational information. Methods and models of pre-resource planning should be aimed at more eficient use of infocommunication data transmission environment with low bandwidth, as well as to solve the problem of a limited number of simultaneous users (sessions) of the educational process, which put the existing systems of distance and mobile learning. 2.
The modern distributed educational system is characterized by an increase in the variety of types of transmitted trafic in favor of the trafic of multimedia data, in particular, widely used in the online form of distance and mobile learning.
A comprehensive solution to the problem of management of the educational system
is associated with the development of evidence — based methods to ensure efective
management of resources necessary to provide quality educational services and provide
support for a given quality of service, administration and adaptive management in
educational systems [
In contrast to the arbitrary distribution of infocommunication resources, a special case is the management of resources in the systems and networks of remote and mobile education. Information processes of distance and mobile learning are characterized by determinism, poseansnoe loading, a certain consumption of network resources, which allowed to use as a mathematical basis for solving the problems of the theory of the schedule.
Additional significance and an indicator of the weak development of the topic is the
lack of comprehensive work on the management of a distributed system of distance and
mobile education in the presence of limited infocommunication resources. Studies aimed
at the creation and theoretical justification of these methods of resource optimization in
the organization of the educational process are in demand both at present and in the
foreseeable future of the development of educational systems [

In General, the construction of software and hardware complex, is an organizational and technical problem, in relation to which the choice of the method of playback of online remote and mobile education, is associated with the solution of the little-studied problem of formation of the organization of management of the broadcast of educational information in real time.
In the organizational plan of formation of hardware and software complex of
preparation and creation of courses is connected with a problem of formation of the corporate
portal intended for implementation of educational activity in a global network. As part
of such a portal can be divided into three main functional layers that determine the
efectiveness of its functioning [
Since the organization of information exchange is based on the client/server organization of information resources of the system (in which the process of data exchange between the client and the portal becomes centralized), the content management of the portal consists, firstly, in regulating the functioning of the application server and, secondly, in determining the moments (priority) of information exchange, based on the type and volume of trafic transmitted in comparison with the current load of technical means employed in ensuring the appropriate information and communication exchange.
The task of managing the organization and control over the translation of educational
information is time-consuming, since the characteristics of communication channels can
vary depending on the territorial location of students and their technical capabilities.
Therefore, a preliminary analysis of the possible options for the distribution of the
current bandwidth of communication channels, taking into account the qualitative and
quantitative characteristics of electronic training materials is a fundamentally important
stage, prior to the transfer and processing of information flows in the networks [
In this regard, it draws conclusions about the need for pre-planning the allocation of network resources in a joint transfer of certain amounts of priority and non-priority trafic, during the implementation of the interruptible and non-interruptible educational work. The implementation of such a plan could be proactive redundancy of certain channels (connection repackaging method) and/or trafic prioritization.
The main components of the organization of information management system of distance and mobile education (SDME) are the task of discipline and algorithm of classes in each of the disciplines, the number of students involved in the disciplines, as well as the value of performance (resource intensity) of network technical means SDME. The utilization means to characterize the adequacy of distributed SDME for the tasks.
Based on the results of the analysis of the structure, information and management processes in the SDME was created a number of models and algorithms underlying the management system of distance education. CA ERWin Process & Data Modeler tools were used to develop the process models and database of the information system for SDME management support. A functional model of each process of the network system of distance education was built in the form of a set of elements — subprocesses that interact with each other. Figure 1 shows the top-level context diagram of the functional model. On the basis of the functional model the diagram of variants of use of processes of functioning of information system of support of management of SDME was developed.
The next step is the development of algorithms for execution of the main processes. Figure 2 shows the interaction algorithm of the “Create tools BEFORE” process.
Described database model implemented using IDEF1X methodologies and CASEtools CA ERWIN Data Modeler. The first step was to determine the entities and relationships between them, identified in the course of a multidimensional analysis of the subject area. ER-, KB-, FA- and T-models of the database were formed on the basis of the identified relationships and data on the presence of key attributes of entities.
Based on the transformational database model of the SDME management support system, a DBMS model was developed in the form of XML-code. The interpretation of this code allowed us to obtain a database scheme in the format of DBMS 1C: Enterprise at the physical level.
Thus, all the necessary models and algorithms were created to implement the information system to support the management of SDME — an efective tool for the distribution of infocommunication resources.
