Formation of centralized uniform department of information technology is not always cost-effective
in large structured geographically distributed enterprises. The objective of the article is to develop
recommendations for organization of effective technical and reasonable cost management system IT
services for large institutions. Is generally recommended to use ITIL for IT management. The model
of IT services catalog is simple, it ignores technical and system aspects of IT services. It has been observed,
the idea of centralization and systematization IT services through service catalog is failing
in practice. The article proposes algorithm of distribution IT services by the organizational structure.
The algorithm considers the budget management, technical and system aspects. Reasons for and consequences
of the transfer IT services to not specialized subdivisions were research. As a result, the
new distribution IT services allows creating more efficient organizational structure of IT department.
IT department focuses on infrastructure and system-wide problems, it permits to decrease information
technology costs. The article presents examples of the distribution IT services for University and
Network of State Institutions.

Comprehensive, accurate and qualitative information is the basis of research, decision-making and
management activities at different levels and applications. The non-trivial cases to obtain data related
to the solution of complex problems and requires establishing special data collection or monitor system,
the traditional approach to the construction is based on pre-formed requirements derived from
system analysis stage. However, the actually observed processes due to their unpredictable character
are typically different from expected ones having highly variability of their parameters’ values and
behavior styles thus reducing the originally built monitoring system efficiency because of ever-growing
discrepancy between the initial objectives and actually observed environment. The solution may
exist in creating a system of adaptive monitoring, featuring flexibility to change its structure and behavior
depending on changing conditions. The paper describes the fundamental concepts for building
systems in an adaptive manner taking into account and generalizing the accumulated experience
of implementing this approach. We indicate the possible adaptation areas, describe the main system
components and objects, such as triggers and indicators, enumerate the requirements they should meet
and enlist the recommendations for their design. In addition, the possible IT technologies, platforms
and application systems examples that implement an adaptive monitoring approach are highlighted.

The problem of quality management system automation of the Russian enterprises and organizations
is actual in connection with the raising quality requirements of the made production and services
caused by the entry of Russia into the WTO and EurAsEC. The analysis of the Russian software market
showed lack of prototype software solutions in the field of automation of quality management systems
of the organizations. Some functions on quality control of productions/services are implemented
only in the ERP system «Galaxy». On the other hand, the foreign market is saturated with the software
for the system quality management automation. In the course of research, the problems of the automation
of the systems of quality management connected with specifics of quality management document
turnover, registration procedures, the assessment and the analysis of quality of raw materials and finished
goods, staffing of such systems were revealed. By the results of the research the basic provisions
of the methodology of designing of the automated quality management systems have been formulated,
including some basic principles structural and object-oriented approaches, which include: the principle
of functional decomposition, the principle of consistency, the principle of access to the end user, the
principle of encapsulation, the principle of structuring data with the use of relational data model, the
principle of feedback (interaction with the consumers), the principle of visualization of processes, the
principle of process identification, the principle of process controllability, the principle of controlling
with the implementation of 8D method, the principle of integration of electronic forms of documentation,
the principle of adaptability of electronic forms of documentation, the principle of a flexible
configuration, the principle of the automated assessment, the principle of group clustering. All considered
theoretical principles are discussed in detail in this article.
The formulated concepts have been tested in the design of the automated systems of quality management
of the specific businesses.

One of the approaches of chemical manufacturing information support is model-driven engineering
which focuses on the abstract representation of the knowledge as the domain model. From one
side, domain models are intuitive and user-friendly for the expert. From the other side, such models
are formal and can be translated to software constructions. The IDEF specifications are used for the
model definitions creating. First, we provide the generalized functional model on the basis of informal
descriptions of one-step chemical manufacturing. We begin with top-level context diagram to specify
the main inputs, outputs, controls and mechanisms of the chemical manufacturing. From this diagram
the derived diagram is generated. The derived diagram describes the sequence of base technological
steps such as row materials preparation, chemical transformation, product refinement and condensate
separation. The quality inspection is added to the end of the sequence. Feedback arrows present recycles
of raw materials. Then the implementation of this model for the production of methyl tertiary butyl
ether is described. The detailing of the generalized model means naming of functional blocks and
arrows while the model structure does not change. So the generalized model can be treated as a template
for any chemical one-stage manufacturing model.

In the conditions of informatization of all fields of activity the improvement of processes of life
cycle of the automated systems defines functioning of any enterprise in general. In this regard the importance
of the university graduates competence formation increases. Professional competences define
the degree of IT specialists in information systems readiness to carry out different types of tasks.
The requirements of employers were analysed according to which the model of future expert in the
field of information systems is developed. The article is focused on the continuity principle that is realized
though the chain «competence — subject — competence — subject». The complex of methods,
forms and techniques is used for conducting classes and organizing extra class activities and studying.
A certain competence formation of university students within an educational curricular is carried
out through a number of disciplines and their close interrelation on the basis of continuity is assumed
that is realized though curricular, in the principles of statements of design tasks, application-oriented
tasks, including laboratory and course papers, educational and work practice, etc. Continuity principle
in subjects curricular planning defines completeness of formation as one of significant factors of
increase of efficiency both the process of formation of competences, and educational process in general.
The materials of the research can be used for IT-specialists training at higher education institution.

The article discusses the international standard of education Computer Science Curricula 2013 and
provides an analysis of its substantial aspect. Currently information technology is one of the fastest
growing fields of knowledge, that iswhy it is urgent of what and how to teach. So there is a need to analyze
the accumulated international experience in this area. For computer science this international experience
is concentrated in the document entitled Computer Science Curricula. Current version of this
document is Computer Science Curricula 2013 (CS2013). The most interesting is the analysis of requirements
for graduates in the field of Computer Science, such as Technical understanding of computer
science, Familiarity with common themes and principles, Appreciation of the interplay between theory
and practice, System-level perspective, Problem solving skills, Project experience, Commitment to lifelong
learning, Commitment to professional responsibility, Communication and organizational skills,
Awareness of the broad applicability of computing, Appreciation of domain-specific knowledge. Another
side of CS2013 are Knowledge Areas of Computer Science: Algorithms and Complexity, Architecture
and Organization, Computational Science, Discrete Structures, Graphics and Visualization, Human-
Computer Interaction, Information Assurance and Security, Information Management, Intelligent
Systems, Networking and Communications, Operating Systems, Platform-based Development, Parallel
and Distributed Computing, Programming Languages, Software Development Fundamentals, Software
Engineering, Systems Fundamentals, Social Issues and Professional Practice. CS2013 and Russian standard
of higher education in IT have much in common, but also there are some differences in courses,
ways of teaching and graduation requirements.
